Post-Academy Awards Special Backmarker: The Colonel's Motorcycles



In the 1930s, the Nazis knew that the next war would be far more mechanized than the last one. They encouraged the FIM to create an ISDT Trophy for the top military team.


The 1939 International Six Days Trial was held in Nazi-controlled Austria. With the political situation worsening by the moment, it seemed that Britain’s teams - especially the military dispatch riders competing for the Huhnlein Trophy - were destined to become P.O.W.s before the first shots were even fired. Instead, they climbed on their BSAs, Matchlesses, and Nortons, and rode around the clock to reach safety in neutral Switzerland. Finally, after another marathon ride, they arrived home just as war erupted across Europe.

Adolf Hitler was born in Austria, and remained an Austrian citizen until 1925. If anything, his National Socialist German Workers’ Party–the Nazis–were even more popular there than in Germany. In March 1938, Hitler’s ‘Anschluss,’ made his old homeland part of the Third Reich. A few days later in Vienna, he was given a hero’s welcome. Indeed, though Austria was to account for only 8% of the Reich's population, Austrians would soon make up 14% of the SS, and over 40% of the personnel involved in genocide.

The Nazis were masters of turning international sporting events into propaganda opportunities. The '36 Olympics were the most famous instance, but they also co-opted and encouraged BMW's land-speed-record attempts, and took advantage of the 1939 International Six Day Trial.
A prestigious international sporting event was just the thing to legitimize the Nazi’s new status in Austria. Since Germany had earned the right to stage the upcoming International Six Days Trial–often called the ‘Olympics of motorcycling’–they chose to hold it in Salzburg. It was a spectacular alpine setting, already the home of a major music festival (and of the Von Trapp family singers, of ‘Sound of Music’ fame.)

While Hitler consolidated his power, Britain (and the United States) responded to his political bullying and ominous military buildup with a mixture of appeasement, and their own half-hearted rearmament. Military strategists on both sides realized that the next war would be far more mechanized than the previous one.

Motorcycles would play a small but significant role in modern warfare. The British Army realized that the ISDT was an excellent test of military motorcyclists’ combat readiness. So, in 1938, the Army entered a team in the Six Days (that year, the event was held in Wales.) Three soldiers from the Royal Tank Corps; Fred Rist, Paddy Doyle, and Jackie Wood, did well. But overall, the Army team was poorly prepared, and their performance proved that military riders, machine specifications, and preparation had fallen far behind their civilian counterparts.

Shortly after the Army riders’ embarrassment in Wales, Britain suffered a more severe humiliation. The British Prime Minister flew to Munich, planning to mediate Hitler’s claim to the Sudetenland (an ethnic-German area in Czechoslovakia.) Chamberlain returned to England, and crowed that he’d “established some degree of personal influence over Herr Hitler.” This news delighted Britons, who were still recovering from the last war. But in fact, their Prime Minister had been completely bullied by the Fuerher, and had thrown Czechoslovakia to the wolves.

Through the first half of 1939, the British Parliament reassured the population that war was unlikely, but their actions belied their words. They published evacuation plans in the London newspapers, and dug trenches in public parks, for use in air raids.

The motorcycle press was no less contradictory. In early July, Graham Walker (the influential editor of ‘Motor Cycling’) wrote about the coming I.S.D.T., “No thinking person can ignore the gravity of the present situation, nor the oft-repeated suggestion that August may be a month of crisis.” But, he went on, “The Germans and Italians did not question their safety when visiting the Isle of Man in June and we see no reason why we should query the safety of our visiting Germany in August.” Besides, the Auto-cycle Union (A.-C.U.) had been assured by the event’s ‘Oberfuhrer,’ that if war broke out, all competitors would be given safe passage to their borders.

After their rude awakening at the ’38 I.S.D.T., the Army vowed to redeem themselves. Dispatch riders were encouraged to enter civilian competitions. They were allowed to use their issue machines, and provided with free fuel and oil. Rist, the Tank Corps Sergeant, took advantage of this ‘sponsorship’ to win the Travers Trophy Trial, an achievement made more noteworthy by the fact that he was still virtually a novice. Later, he teamed up with his fellow corpsmen, Doyle and Wood, to win the team event at the Cotswold Cup Trials. By beating several high-profile manufacturers’ teams, the trio established themselves as the cream of Army riders.

In June, the Army assembled a dozen crack riders under the command of Colonel C.V. Bennett. They were to spend the summer at Aldershot (an English military base) in full-time preparation for the Six Days. Their goal was nothing less than to win the Huhnlein Trophy, which was the award presented to the top military team. Over 11 weeks, the soldiers would train and be tested, then three squads of three riders would be selected to go to Salzburg.

The rear shocks on these bikes identify them as post-war Goldies, but this gives you a sense of what the bikes (and guys) in this story looked like.
Bennett leaned on the manufacturers of the Army’s motorcycles (BSA, Norton, and Matchless) for support. Each firm agreed to prepare works machines for the trial, and provide a factory service representative.

The team’s daily routine at Aldershot began with calisthenics and swimming, led by Sgt. Rist. Then there was riding practice on sand, grass, and gravel. They were tested on everything from changing tires and cables to assembling carburetors and clutches. Daily ‘trials’ of up to 200 miles often lasted until late in the afternoon. In the evening, each rider returned to his quarters with his machine, where he performed his own maintenance. Bikes were presented for inspection at 8:30 a.m. the next morning, and the cycle began again.

Factory experts gave workshops on set-up and service, and a technician from Dunlop taught them the fastest way to change a tire. In July, the Army lads were invited to the Bagshot Heath scrambles track, where they watched a special committee of the A.-C.U. select elite civilian riders for the British Trophy and Vase teams.

The Army brought in the country’s top scrambles riders as visiting coaches. They booked Brooklands and Donington for high-speed practice. Bennett was taking his job seriously; at the end of the month, the ‘International’ team was inspected by Major-General H.R.S. Massy, no less than the Director of Military Training.

On August 8 Britain’s future leader, Winston Churchill, spoke on American radio. A hush had fallen over Europe, he said, “It is the hush of suspense, and in many lands it is the hush of fear.”

At Aldershot, there was suspense too, as Bennett selected the riders for Salzburg. They were:

Sgt.-Major B. Mackay 347 Matchless
Sgt. O. Davis 347 Matchless
B.Q.M.S. E. Smith 347 Matchless

Lieut. J.F. Riley 490 Norton
Sgt. J.T. Dalby 490 Norton
Cpl. G. M. Berry 490 Norton

Sgt. F.M. Rist 496 BSA
Cpl. A.C. Doyle 496 BSA
Pte. J.L. Wood 496 BSA

The Matchlesses and the Nortons were standard-issue models, which were to see plenty of service in WWII. The Matchless G3 was a 350 c.c. overhead valve single, with a four-speed transmission. It made about 16 horsepower, and weighed 328 pounds. The Norton 16H was slightly less up to date, making just 14 horsepower from 490 c.c. It weighed 388 pounds in standard trim. The Matchless was fitted with a modern, oil-damped telescopic fork, but the Norton still relied on a girder fork, with a friction damper.

The British Army used two BSA models, the 350 c.c. B25 and the 500 c.c. M20. The M20 was heavy; its side-valve motor was wide. All in all, it was hardly a bike you’d recruit for a serious trial (though some were fitted with 21-inch front wheels, and used in competition.) Not leaving anything to chance, BSA equipped the ‘International’ team with their newest Gold Stars.

Towards mid-August, the team set out on their competition machines towards Salzburg, in order to get practice on ‘continental’ roads. They were accompanied by a loose convoy of over 50 civilian competitors (making up the Trophy and Vase teams, as well as club and manufacturer’s teams.)

A number of British fans also tagged along, one of whom later wrote, “‘Germany! Do you think it’s wise?’ How many times did we hear this before setting out to spectate at this year’s International? If anything, the dismal Jimmies spurred us on even more with their morbid, pessimistic remarks.”

Most of the British arrived a few days early. Salzburg’s streets were decked with Nazi regalia–decoration for the music festival, and because Hitler himself had established a summer base 15 minutes away at Berchtesgaden. One night at the opera, the crowd’s opera glasses spent as much time trained on one of the balconies, as they did towards the stage; Herr Hitler was in the house.

There were so many uniforms in evidence at the Six Days’ check-in–both amongst the competitors and the organizers–that some of the civilian riders grumbled they almost felt out of place. General Huhnlein (of Huhnlein Trophy fame) was present at the start on the first day (Monday, August 21.) Riders took off on a 295-kilometer loop into what had, only the previous summer, been the free country of Czechoslovakia.

The first day of the 1939 ISDT sent riders out on a route that was relatively easy, but it still took its toll on the Army teams. Berry (Norton) came off after hitting a dog. The crash destroyed his twist-grip, but he continued, pulling the bare cable to control his throttle. Later that day Smith (Matchless) was blinded by the dust of a passing rider, and hit a bus! He continued with bent forks. Finally, Lieut. Riley’s Norton split its gas tank. The Army’s BSA team of Rist, Doyle, and Wood, however, lost no marks, and was going strong.

Tuesday’s loop was shorter, but sharper. A number of competitors retired, including two of the Army’s Norton riders, and one from the Matchless squad. On the Nortons, Berry gave up when his replacement twistgrip would not work. Riley had managed to seal his cracked fuel tank with soap(!) earlier, but the split worsened. Smith, on the Matchless, finally succumbed to the bent forks and wheel he’d suffered in his previous collision.

On the same day, the Reich concluded a treaty with the Soviets. German riders and officials reacted warmly to this news. They believed their own propaganda, which suggested that the treaty reduced the risk of war with Poland. In fact, the opposite was true. One of the treaty’s secret clauses gave eastern Poland to Russia. Hitler no longer needed to fear that his attack on Poland would anger the Russians, who also craved Polish territory.

This was what the dictator had been waiting for. He convened a meeting of his top generals at his summer headquarters - they must have almost been able to hear the roar of trials motorcycles in the clear mountain air - and told them his decision to invade Poland was now “irrevocable.” They were instructed to have their forces ready to move by the weekend.

The Grossglockner Pass is still one of the motorcycle roads in Europe. In the 1939 ISDT, competitors raced over this route. Note that the road was not closed for the racers' use.
Wednesday’s route took competitors over the Grossglockner pass, a 23-kilometer climb that included numerous hairpin turns. Even at the end of summer, the surrounding peaks were snow-capped. A late thunderstorm put down the dust, and seemed to favor the British riders. That evening, competitors crowded around radios listening to the BBC news broadcast; they heard that France had ordered its citizens to leave Germany within 24 hours. Several racers suggested the British contingent should do as much, but the team managers were against the idea, especially as there were British teams poised to win all the important trophies. The British civilians were heartened by the fact that their Army team seemed perfectly calm.

On Thursday, British competitors again took to the course, while team managers sent telegram after telegram, desperate for any information or advice. Their uncertainty lasted into the night, until Norton Motors wired instructions that their team was to withdraw and return right away. Moments later, the British Consul General in Berlin warned all British subjects to leave Germany immediately.

By 7:30 a.m on Friday morning, all but a handful of the British civilian competitors had left Salzburg, headed for Switzerland. The German organizers begged them not to go. Event officials, all Nazis themselves, promised the team managers that if trouble started, they would accompany them to the border themselves to ensure a safe passage.

Marjorie Cottle was the only civilian competitor who stayed behind when all the other British civilians were told to leave Germany after the fourth day of competition. Her attitude seems to have been, "If the Army boys will stay, I'll stay." In my screenplay, I gave her an ulterior motive... (cue fanfare from James Bond theme, by composer Monty Norman.) Cottle doesn't actually need to be over-dramatized; she was one of the best and toughest female racers of all time, and competed in ISDT events in three different decades.
The British military team stayed behind, however. Colonel Bennett considered it their duty to compete unless he received specific orders to the contrary. At 5 a.m., while the civilians were frantically packing and loading their machines, the Army’s lads withdrew their bikes from the enclosure, and headed off according to schedule. One exception was Dalby, the final Norton runner, whose gas tank had also begun to split. Col. Bennett didn’t want to risk one of his men being stranded alone in the countryside, so Dalby was withdrawn from competition. Things seemed calm enough, and after seeing his riders off, Bennett and Bert Perrigo (who was tagging along as BSA’s technical representative) went for a swim.

When they returned to their hotel, they found orders from the War Office instructing the team to leave for Switzerland immediately. Ironically, the orders had been issued Thursday, before the civilians had been told to leave, but the paperwork had mysteriously been delayed in transit!

While they must have had their doubts about the political situation, the BSA squad under Rist’s leadership were still in the running for the top military trophy; in fact, they had not lost a single point between them in five grueling days.

On paper, the sixth and final day - Saturday - was to be the easiest by far. It began with an easy dash up and down the autobahn, and concluded with one last ‘special test.’ Perrigo, BSA’s factory man, suspected that Nazi officials had smoothed the final scrambles course as much as possible in order to suit the German motorcycles, which were fast but heavy. In spite of this, he was sure the Huhnlein Trophy was within their grasp. He noted the similarity between the final test and the team’s practice tracks at Aldershot and Bagshot Heath.

Perrigo’s optimism was probably well founded. (Rist became a legendary sandtrack racer after the war; so he, for one, would have done well on the smooth, gravel track.) This much is certain: the symbolism of a team of British soldiers, accepting their accolades from a German general at such a moment in history, would be lost on no one.

But as the tired riders reached the Friday check in, they found Col. Bennett waiting with new orders: prepare for immediate departure. The Army also took four civilian competitors under their wing (including Miss Marjorie Cottle, the only woman in the field.) The British convoy consisted of riders and ‘fitters,’ officers, factory reps, and another woman, Miss Bunge, representing the A.-C.U. They formed a column of two trucks, two cars, and fifteen motorcycles. They were accompanied by Bennett’s German liaison officer, the very downcast Col. Grimm,

The British ‘Internationals’ were far from the only soldiers on the move. The German invasion of Poland was set for 4:30 a.m. the next morning. Well over a million German troops began moving towards the border under cover of darkness.

Fuel was tightly rationed, but Herr Jaeger, of Shell’s Munich office, provided the group with enough precious gasoline to get to Switzerland. The British contingent - their day had begun so long ago, at 4 a.m. - rode right through the night. Streaming past in the opposite direction, an endless military convoy, headed for Poland. Once, the motorcyclists were halted and questioned by German soldiers at length, until Grimm came to the rescue. It was pouring rain, and cold. Despite this discomfort, they were so utterly exhausted that more than one rider dozed off, waking with a start after hitting the curbs.

In hindsight it seems certain that the German organizers would, indeed, have done everything in their power to ensure the safety of the competitors - even if Britain had declared war during the event. Afterward (when the war was in full swing and propagandizing was rife on both side; when few Brits could bring themselves to say anything remotely nice about the “Krauts”) Major H.R. Watling, the Auto-cycle Union’s Steward admitted, “The courtesy of the officials of the O.N.S. and N.S.K.K. towards British competitors remained undiminished.”

It’s a moot point anyway because that night, Hitler had a rare crisis of confidence. First, Britain reaffirmed its commitment to come to Poland’s aid. Then, Mussolini screwed up his nerve and informed Hitler that Italy’s military was not yet ready to help if Britain (or France, for that matter) joined the fray. The Fuerher called off the invasion. Poland got a brief reprieve, although it took hours for new orders to reach all the men in the field, and the escaping motorcyclists noticed no reversal of the Germans’ mobilization.

So, on the morning of the sixth day, instead of charging off to capture the Huhnlein Trophy, the Army team crossed into Switzerland. After seeing the last of his men to safety, Colonel Bennett bade farewell to Col. Grimm, and stepped across the border himself. It would be a long time before an officer of the British Army would again shake hands, as a friend, with of an officer of the Wehrmacht.

The British contingent rode almost nonstop through Switzerland and across northern France, to the ferry docks at Calais. They were no sooner home than the war was on for real. England declared war on Germany on September 3, 1939. The United States entered the war two years, three months, and eight days later.

Left to compete in their event virtually alone, the Germans won all the major ISDT trophies. The results were never ratified by the FIM.

Quite a story, eh? After compiling an outline, I queried Cycle World, and the magazine said it would run it as a feature. I traveled to England to research the events of 1939 in the British Library, at the Imperial War Museum, and at the National Army Museum. I wrote it up and sent it to the magazine, but it was eventually killed because the then-editor didn't think they could support it with enough photos. I was told that it might run if I could get a lot of pictures from the event, preferably in color. It was 1939. It's unlikely anyone even shot the event in color. But it eventually ran in Classic Bike.

It was one of those great tales that, every time I told it, somebody said, "That should be a movie." I asked the only filmmaker I knew at the time, Peter Riddihough, how to start and he suggested that I just write out the story, which I did. I wrote a novella-length account of those events which was very true to the historical facts. I made up dialogue where needed and filled in gaps with plausible action. 

As a racer, the thing that fascinated me was the should-we-stay-or-should-we-go debates that I know must have taken place. They worked so hard to get to the ISDT, and to have to leave while in a position to win must have been agonizing. 

I shopped that story around with no success, hoping to find an experienced screenwriter who wanted to share it. I'd registered it with the Writer's Guild, so there didn't seem to be any reason not to put it on line. I posted it on the old Road Racer X web site one Thursday, and the next day I got a phone call from Davey Coombs, who asked me if it was all right for him to give my number to Matt Leblanc, who had called Davey after reading the post (those two knew each other from somewhere; Leblanc's an avid motorcyclist and Davey basically owns the sport of motocross in the U.S., so I wasn't surprised they were connected.)

Within hours, I got a call from some lawyer at Warner Bros., wanting to know who my agent was. I was told that they were going to make an offer to buy the rights to my account, and that I could expect a written offer to be delivered by courier within days.

I thought that was pretty cool.

Hollywood, someone once said, is the land of the slow no.

No offer ever came. I suspect that someone in WB's legal department said, "Wait a minute, this is all a matter of historical record, we don't have to buy this, we can just appropriate (read 'steal') it." While the underlying facts are matters of record, just taking an entire, original journalistic account of a historical event and using it as the basis of a film would put a producer on pretty shaky ground. My account was compiled from a number of period sources, and because the version posted above is based on a concordance of a number of accounts, my version actually spells out certain details for the first time. (If this happened, and this happened, then it follows that this must have happened.)

Anyway, when they never followed up I did what every other semi-employed guy in SoCal does; I bought a copy of Final Draft and wrote a screenplay. My first version of The Trophy stuck closely to my novella (and the historical facts.)

It got nowhere. Perhaps because it was not contrived to create conflict in every friggin' scene, and there was no bloodshed. Ismail Merchant was dead, and so was my movie.

I finally compromised and rewrote the film, sticking as close as I could to the historical record while injecting just enough conflict, romance (and yes some bloody violence) that it might, conceivably, get funding in Hollywood. I circulated to everyone I know with a degree or two of separation from the film business. My friend Jeff Buchanan who grew up in the movie business (his dad was a cult-hero director of sci-fi 'B-movies) read it and told me he hated it. He called me up and  point-by-point excoriated everything I'd done to the story in order to get it made.

Since Jeff has conspicuously good taste, I knew I was finally moving in the right direction to get it made.

Anyway, I think I'm possibly (pause while blogger touches wood) finally close to making an announcement about this film. While the popular assessment in Hollywood is that any period script, any costume drama, any movie with accents has one, two, three strikes against it... if The King's Speech does well tonight, The Trophy stands a slightly better chance.

The civilian competitors at the '39 event were taken aback by the predominance of Nazi uniforms. The event was actually organized by the Nazi party, and there was as much interest in the Huhnlein Trophy as there was in the 'main event.' For a few beautiful pictures that set the scene, go to the speedtracktales website. It's great.
The foregoing material has been registered nine ways from Sunday. Trust me, it'd be cheaper to buy it than steal it. Have your people call my people. Oh wait, I don't have people.


The Freeride: A new playboat by Liquidlogic

Maria sitting pretty in the new Freeride by Liquidlogic

(If you would like a theme song for the Freeride scroll all the way down to Edgar Winters video and press play, if not just keep reading and looking at pretty pictures.)

The Liquidlogic Freeride 57 spins into the final cycle of the design process this week.  What’s been fun with this one is that it was a boat that we had started designing a while ago and then you all requested it from us through feedback on our facebook page.  Your feedback in discussions helped us fine tune and polish the completion of this model.  This communication also brought momentum to a mission that we have taken on fully here at LL and that is the "automatic for the people revolution".  In the coming years, we aim to bring you all what you want, to ask you for your advice and run with what we hear from you.  For that I can already say big thanks, you've inspired us to push forward on even more new stuff at Liquidlogic. 
And now the rest of the story.


A couple years have passed since the last all new whitewater design at LL. That gave me the time to develop several different concepts to have ready when we were ready to put new designs into our whitewater line.  The concept started with the desire to fill the vacancy left by the CR series, but with this advance in the playboat concept we added a more play performance-oriented hull shape and slicier volume distribution to a very stable and comfortable design.

Here are the stats on the boats.

Freeride 57
6'6" long
25.5" wide
57 gallons
xl cockpit

Freeride 67
6'9" long
26.25 wide
67 gallons
xl cockpit


We had paddlers in the 57 ranging from 5'3" and 135 lbs to 6'1" 200lbs.  The weight range seems like it will settle out to be 140 to 210, and the Freeride 67 will be around 180 to 250.  We haven’t completed testing on the 67 so that is an estimate.

Here is what the Freeride looks like in the digital world.  

Click Here to view or download a 3-D PDF that you can rotate yourself.  

PCs may be able to just click and view in your browser. 
Macs will need to download or save the file from the link.  Then open it with a recent edition of Adobe Acrobat. 

Once you have the file open it’s very cool to move around.
If you have a mouse you can use your mouse to click and move the mouse to rotate the model, or with a touch pad just click and move your finger over the pad to move the model.  Hit control and you can also move the model across your screen.

The Freeride 57 model in real life

When we first started talking about the Freeride, Woody and I discussed where exactly we should focus this design and we completely agreed that it should be: more playful than the CR series, easier to roll, faster and looser on a wave, slicier, and still get you downstream predictably.  We decided to make it a great playboat that was easy to paddle.  Of course we knew we wanted it to be comfortable but that’s easy when you put Bad Ass Outfitting in it.  I also added a few special little touches on this boat that some may not even notice.  The drain plug is positioned so that when you put the boat on your right shoulder (sorry lefties We are the minority) the water drains while you carry to the car.  I recessed the cockpit itself for a tighter fit for a skirt so that less water can blast up under your spray skirt, reducing the main way that water gets in your boat.  We also enlarged the size of our cockpits to make getting in and out easier even for Woody-sized people. (and to think, he still hasn’t grown up.)  I’ll share other bonus features in later posts.

Freeride model driven by test dummy

The first prototype of the Freeride kick flipped out like most of my first attempts at a new design.  It was great in some ways and terrible in others.  It had the speed and smooth carving edges I hoped for which made surfing waves easy and fast.  As is normal for me when working on a new design,  I like to pick one attribute or feature from which to build the boats character.  The main emphasis for the Freeride was to make a fast predictable and playful hull.  Followed closely by being an easy boat to paddle.  So I had gotten the hull very close on the first try but the volume in the bow was too much to really deal with when you wanted to cartwheel, especially in flat water.  The stern came through nicely but the bow was a little big.  We took it back to the garage for work.  I dropped quite a bit of volume out of the bow but kept the nose rocker up so the boat would stay on the surface while running the river.

Fergus and Isaac at the Charlotte Whitewater Park. They are dummies as well.

Prototype 2 was a huge improvement.  The lower bow volume made her much more manageable in the ends and the fellas cartwheeled clean and smooth.  They could bow stall much more easily.  We had lighter paddlers in proto number 1 who had a hard time initiating the bow stall but could control stalls and even do flat water loops in proto 2.  The one major downside of proto 2 was an edge that was catching a little on the stern of the boat while trying to cartwheel and run rapids.  It was subtle but could throw you off balance a little every once in a while.  Back to the shop again for proto 3.

Freeride front flip

Prototype 3, which we are paddling right now, feels right on the money.  I added a little more roundness to the stern deck of the boat so that water doesn't have an opportunity to pile up on it.  This really solved the slight edgy feeling I was getting from earlier versions.  The ergonomics are lining up really well. I have been paddling this boat with full-sole booties.  So the boat is super comfortable and the performance is really right where I want it now.  We have a few more trips we need to do to completely confirm the design, after all, getting out there and testing is the best part of my job.  

"Yeah, guys, it really looks like I need to go test that boat again today.  I'll see you later."  :)

Here is a little teaser video on the day we paddled with hundreds of ya'll on the Cheoah.

And of course the theme song for this boat will be...

Stay tuned for more updates on the Freeride which will be coming to stores in June.  Just in time for some summer lovin' 1972 style.
More posts to come about the Freeride!

Vasari – louvered façade

Ok, apologies, but it has been a number of few weeks since I have posted anything! Things are picking up here in London so I have been really busy, but this is really not an excuse! Anyway, I thought I’d pass this little modelling tip on to you. Somebody in the office asked me a a few weeks back whether it was possible to create a parametric louver system which could be used on a facade for a freeform building they where working on.image

The louvers needed to be parametric so that they could adjust the angle of the louvers as and when required, to meet the environmental conditions. image

So I knocked this solution up with the user sat at my desk inside 10 minutes using a combination of points, nested adaptive components and curtain wall pattern based families. The original example was completed in Revit Architecture 2011, but the youtube video was done in Vasari 1.1. Sorry, there is no sound / voice over, but hopefully I have done the exercise slow enough for you to follow along!

The most important component on a motorcycle should always be the rider

Judging from the timesheets issued at the end of each day at the Sepang MotoGP test, there was a lot of formation flying going on, with groups of similar machines closely spaced at the end of each day. The effect got more pronounced as the test wore on, until finally at the end of Day 3 the results looked like this...

  1. Casey Stoner Honda 1:59.66
  2. Dani Pedrosa Honda 1:59.80
  3. Marco Simoncelli Honda 2:00.16
  4. Andrea Dovizioso Honda 2:00.54
  5. Ben Spies Yamaha 2:00.67
  6. Colin Edwards Yamaha 2:00.96
  7. Jorge Lorenzo Yamaha 2:01.00
  8. Alvaro Bautista Suzuki 2:01.19
  9. Hiroshi Aoyama Honda 2:01.32
  10. Hector Barbera Ducati 2:01.34
  11. Valentino Rossi Ducati 2:01.46
  12. Nicky Hayden Ducati 2:01.46
  13. Loris Capirossi Ducati 2:01.49
Since there's only one Suzuki in the field, that brand is 'grouped' by definition, but in the front 3/4's of the grid, only Aoyama seems to be out of the prescribed order. That distribution of bikes reminds me of the mid-'90s when I finally stopped watched F1 car racing. By then, the grid would be formed of pairs of identical cars. That, disappointingly, always suggested that drivers had little to do with the overall results — drivers’ skill or daring only mattered enough to influence the results when all other variables had been controlled for; ie _within_ their teams. I longed for the days before traction control (and ABS) had turned F1 cars into (admittedly breathtakingly fast) robot cars. I wished the genie could have been put back in the bottle, and when a driver with plenty of bottle, like Gilles Villeneuve, could overdrive his Ferrari 312-T4, which was an inherently compromised design (its flat-12 motor was unsuited to ground effect aerodynamic design, which had just emerged as the trend-of-the-moment.) Skip to about minute four of this video, and watch the last couple of laps of the 1979 F1 French GP, and remember that there was a time car racing was as exciting as motorcycle racing - and more exciting than motorcycle racing is now.



While there’s no denying that the road _to_ a MotoGP seat is still very, very difficult and everyone is scary fast, these results make me suspect, again, that the machines are fitted with too many rider aids, which reduce the significance of the rider in the overall equation.

At the Indy show, I heard Chris Van Andel of Motion Pro mention that one Superbike team had requested a special, extra-large spool for their Revolver adjustable throttle, with a diameter that would result in about a 1/8th turn throttle. “I can't imagine controlling a bike with such a quick throttle,” he mused. Someone else noted, “I guess they're just letting the traction control do all the work.”

I miss the days when lap times depended most on a single component: the nut connecting the handlebars to the seat. I hope these results don't mean that if you’re fast enough to get to MotoGP, once you’re there you’re only as fast as your machine and there’s little you can do about it. If it really turns out that rider input variations are less than the deviation between ‘brands,’ that will be bad for MotoGP.

Of course, over the course of a season or contract, a brilliant rider might be able to make such a contribution to his bike's ongoing development that he could shift the balance of power. Let’s see, for example, if Lorenzo or Spies has the quality of input that will allow Yamaha to keep winning. Or if Rossi can raise Ducati’s game. But even that doesn’t redound to the specific development rider as much as to the team as a whole.

I'll stop saying traction control's gone too far eventually, I suppose. But it's clearly 'better' than the best riders now. I'm not saying MotoGP's easy or that I could do it, because I know I can't. But how long will it be before ABS or even computerized lean control provide superhuman braking and turn-in?

At that point, we can all turn off.

Have You Licensed Your Canoe or Kayak Yet?

TheStar Boaters fear they’ll be up a creek without a $50 licence

The above article refers to an issue that's recently come up in the Canadian paddling community, Transport Canada's new regulations that seem to require the licensing of canoes & kayaks.

This item also appeared in today's CBC News: http://www.cbc.ca/news/canada/ottawa/story/2011/02/25/ottawa-canoe-rules.html

I've been aware of the issue for well over a month now, and have resisted blogging about it, primarily because I was waiting to see what it all means, and hoping for clarification of several points. To that end I have been reading the information put out by Paddle Canada, and PaddlingInstructor.com, as well as following closely (but not getting mired into) the conversations at Canadian Canoe Routes and West Coast Paddler.

These rules are confusing, and there has been a great deal of confusion of how these rules will affect local paddling clubs (like the SCC), Guides, Scouts, schools, and other organisations that are important for introducing canoeing and kayaking to new paddlers.

As an instructor, it's not not the end of the world for me. As someone who occasionally volunteers to take the less experienced out on the water in canoe and kayak, this could be a very big deal. I've been hesitant to take a stance while I've been trying to figure out what it all means. However, I'm more and more of the opinion that this is a bad thing for individual paddlers, and for paddling culture in Canada.

During discussions of these new rules it gets brought up that it will be impossible to enforce. That may be, but they don't need to enforce it at all for it to be very important. It suddenly becomes important when something bad happens on a trip, course or minor excursion, and you are deemed to be a leader.

The good thing here is that they perhaps seem to be backtracking a bit, based on the comments from Chuck Strahl, Federal Transport Minister as reported in the above CBC article.

So, if you paddle, especially if you take others paddling, look into this and form an opinion for yourself. Keep an eye on how this is progressing and if your not satisfied or if this has you worried, consider writing a letter expressing your concern to your elected representatives. Also, spread the word. I think very few of us even know about these regulations at the moment, though the news is spreading.

World's luckiest Indian?

A friend of a friend forwarded this shot of, yes, 'The world's fastest Indian' which now resides in the Hayes Hardware store in Invercargill, on New Zealand's south island. Invercargill is pretty far from Christchurch, so this building wasn't at risk during the recent earthquake. It did, however, dodge a bullet during the 2009 quake that wreaked havoc on Invercargill itself. The photo came to us with no explanation as to how the bike ended up in the hardware store. Maybe Burt Munro ran up such a tab that it was the only way to repay the merchant.

Notable engineer countdown - at #6, Fabio Taglioni – adapted desmodromic valves to motorcycles

I'm sorry, I couln't resist. I'm told this guy's an avid motorcyclist. For a photo of the real Fabio Taglioni, go here.
Taglioni was the chief designer at Ducati from 1954-’89. Although many “Ducatisti” would like to believe that Ducati invented the “desmo” valve system (using a second cam to close the valves, instead of valve springs) the patent was held by Daimler-Benz. Still, it was Taglioni who realized that the system would benefit fast-revving motorcycle engines which, in the 1950s, were limited by the reliability of valve springs. When he mated two Ducati 350cc singles to create the first Ducati 90-degree V-twin, he created one of motorcycling’s truly iconic designs.

up!

The Uber Shelter is up! Genesis and his family are moving in tomorow. The last few days have been incredible for us. We will post stories, pictures and thoughts after some rest.

Racers shouldn't be fat(uous.) And more on James Parker's role in creating the stunning Mission R

So we're about to start another racing season. It's time to start my eye-rolling exercises, so that I'll be ready for more fatuous use of the word 'we' when racers refer to themselves. According to Wikipedia, it was USN Admiral Hyman Rickover who punk'd a subordinate who used the 'royal we' by asking him, "Three groups are permitted that usage: pregnant women, royalty, and schizophrenics. Which one are you?"

I don't even think royalty should use it, but I do agree with Mark Twain who thought there was one more class of person who could legitimately refer to themselves in the plural: people with tapeworms.

I get it. A high-level motorcycle racer is backed by a whole team and, by and large, unless they do their jobs adequately (or at the highest level, unless they do their jobs pretty damned well) the rider has no chance of winning. 

I suppose that in some long-lost post-race interview, the first racer who referred to himself as 'we' may have done so out of a spirit of generosity, in order to share credit for a win with his crew.

His crew would certainly have preferred to share the racer's paycheck.

It's appropriate to give your crew a shout out, but this idiotic use of 'we' has now become a nosism, which is to say that it's actually being used to aggrandize the speaker. Maybe motorcycle racers do it to sound like car racers; maybe car racers do it to sound like stick-and-ball athletes, who really do play as a team. Perhaps some racers' egos are that big that they should be saying 'we,' but until there's a MotoGP bike ridden by a pair of midgets one of whom can just barely reach the throttle and the other who just barely reaches the shifter, or until that new Chinese Moto3 team fields Siamese twins on their bike.. Riders please, refer to yourselves correctly, as 'I.'

The proof of how contrived this whole 'we' thing is, is that while riders self-consciously refer to themselves as 'we' they unselfconsciously refer to their competitors in the singular. I am sure that, in this video clip lowlight of Nicky's '06 campaign, he's not cursing out one whole side of his team's garage...


OK, rant over. I finally got around to transcribing the rest of my interview with Mission R designer James Parker. If you want to read this from the beginning, or need a little background on Mission and its bike, go here. If you're already up to speed, click on the little blue 'Read more' link just below this photo...
Parker and the Mission R, sans battery. The machined alloy plate seen in the horizontal plane at the level of James' left quadricep is, coincidentally, the fourth element of his 'quad-element' frame.
Backmarker: Walk me around the bike and talk about what's noteworthy about your design...

Parker: One thing that was interesting is that the battery is wide. We had to trim the battery around the area of the rider's legs and around the handlebars. We got a CAD model of a Yamaha R6 – it was not something Yamaha did, but it was a CAD model of that bike – and we said, OK the riding position will be essentially identical to the R6. That determined the package as far as the rider was concerned.

But the battery comes almost right to the steering head, so there was no room for me to bend tubes to the steering head. That's why I came up with the 'head box,' which is a machined alloy box that's the full width of the battery and the frame attaches to the outer edges of that.

I had already determined that the motor would provide the structure at the back of the frame. So the frame's what I called a 'quad-element' frame. There's the head box at the front, the motor at the back, the trellises on either side; and the fourth element is a bracing plate that fits inside the battery box and gives it diagonal stiffness.

In a conventional beam frame, you wouldn't need to triangulate it, because the massive beams come in to a central point at the steering head; it is a triangle...

If you look at a rectangle, it can parallelogram. [The Mission R] is really structurally sound. For example, one thing we felt strongly about was wrapping the battery box with the frame elements. We wanted to protect the battery in event of a crash. The battery's stable, chemically, and it's not that delicate, but you still don't want to drag one down the road.

What is going to happen if, no, I should say 'when' someone really wads an electric bike, and the battery's strewn all over the place. Are the corner workers going to clean it up in hazmat suits?

I'm not saying you can't bang up our battery, but it's going to be damned hard. This bike will have to be wadded big time. It can't touch in the lean angle area. That's another thing people have been doing with electric bikes is, people have been... You may have seen some electric bikes dragging in the corners, because people want so much battery volume that they don't give themselves enough lean angle. Czysz had that problem; Lightning had that problem. If you crash our bike, that bottom edge of the battery doesn't touch the ground.

Did you look at a lot of rival electric motorcycles before starting out on this project?

No. We were aware of what was out there, in public. My original design kind of went where Czysz went; putting the batteries on the outside of a spine frame, and there's some attractive things about that, but the vulnerability of the batteries is not a good thing. I don't think people are going to be electrocuted or anything, but there's a lot of chemicals in there that aren't pleasant. It's not like gasoline; gas isn't that pleasant either, but if it catches fire it burns off quickly; if it's sitting there on the track it can be cleaned up.

If you leave the clothes on it, it looks a lot like a sport bike...

One really interesting thing to me was that the motor was shown. The motor's not just a plain cylinder; the ribs on it and some of the other features were designed to make the motor mechanically interesting.

You're the kind of guy who like to work – in your case literally – from a blank sheet of paper. This project took you into relatively uncharted territory; was it more fun than designing an ICE bike?

Parker's working on some interesting gear that will show up on a future generation of this bike, but if I told you what it is, I'd have to kill you.
It was definitely fun. Right from the beginning, I said, People are going to love to look at this motor. I really emphasized that the guys at Mission. The people who are looking at this motorcycle are motorcyclists, and if this bike is for sale, the people who buy it are going to be experienced motorcyclists. So if it doesn't have interesting parts, it's not going to ring their bells.

Is the basic geometry inspired by any particular bike we'd be familiar with?

Because the battery and motor, together, are long I couldn't put a really long swingarm on it. So I looked at the Ducatis and said, I don't want a swingarm any shorter than a Ducati's. Ergonomically and in some other ways, the R6 was a model. There were a few bikes that gave us, I guess you'd say, a sense of confidence that it would work. You know, if we'd made a swingarm even shorter than a Ducati's, would we have been completely confident about the rear suspension? I'm not sure.

We know that works. What about rake and trail?

Yeah, the rake's a little steeper, but it's close. I'll just tell you the Ducati is 24 degrees of rake and just under 100mm of trail, and we're at 23.5 and just under 100.

The angle of the rear shock is striking. It's making room for the motor...

Yeah, it's making room for the motor, but you can see the linkage for the rear shock and it's very familiar.

So there's nothing strange about it from an engineering point of view?

When you design a linkage, the whole thing can be rotated. The way that shock works, in terms of linkage ratios and angles, is very conventional.

Tell me about the rear subframe...

It's a carbon fiber structural part. There's a small steel component where we mount the shock, but the rider's sitting on structural carbon. It's a sweet part. Eventually I'll make one that's all carbon, but this is a good compromise. There's a really nice ride-height adjuster on the rear shock at the top; unfortunately none of the pictures really zeroed in on it.

As a designer, you see the project in stages; on paper, as a prototype, and finally in serial production. Do you expect the serial production bikes to be pretty much just like this one?

Pretty much. There's bound to be some detail changes as we test things and figure out if it works or can be improved. And we have the fact that some of the stuff that's machined from solid will be cast. The headbox and swingarm will be cast if we go to any size of production at all.

When you make the transition from billet components to cast components, are there any major differences? Say in strength...

No, it's more an issue of availability. A cast part needs tooling, so a billet part's cheaper in some ways. It's very hard to make a closed box in billet, but you can do that in a cast part. That's sometimes quite a bit better. Both the headbox and the swingarm, as cast parts, would be closed. You'd have access holes for the casting but they won't be open boxes like the billet parts.

I did a story with Tim Prentice [who was the stylist on the Mission R project] a year or so ago and I asked him then, What's your dream project? And he told me, I'd really like to work with James Parker. Had you guys ever worked together before?

We both worked at Indian at the same time, but we never really worked on the same bikes. I was doing a new engine and frame, and he was styling the existing models. But I've known him for 15 years or more, and I've had him do some stuff for me independently. He really likes the RADD front end; we'd both really like to do that [design a bike with Parker's hub-steered front suspension.]

Tim's talking to BMW about the RADD front end. I approached them and they said, No we're not going to do that. He thinks that BMW should really look at it. Tim also works for Triumph quite a bit, but they've told me directly that they're never going to do a bike with an unusual front end.

As an outsider looking in at BMW they take [design] chances...

They're the only ones that have, other than the real specialist manufacturers like Vyrus. BMW does some really interesting stuff and I hope some day that I can work with them.

That Vyrus has been all over the web. That swingarm is so long and massive, it looks like a hub-steered front end from 20 years ago...

30 years ago! And the amazing thing is, they're using hydraulic steering, which is the kiss of death. If they can make hydraulic steering work, they've got tricks I know nothing about. Bimota tried to make it work on the first Tesi, and [it was a disaster.]

Bikes like the Tesi were adaptable to a steering rod arrangement, because the Ducati motors were narrow, but now they're sort of forced back into hydraulics because they can't wrap the steering rods around the wide Honda motor – that's my guess. But hydraulics just won't work. It will be rideable, but people will not be comfortable with the feel of it; no way.

What was it like working with Tim? Did you spend much time together, or did you sort of deliver a big package and then he took over?

He made some changes to my first design. He felt strongly about the cooling system. I had forward-facing radiators, and he suggested putting the cooling system in the belly pan. And he contributed to the actual tube layout of the trellis frame. You look at a bike like the MV Agusta and you'd think their trellis is just connecting points through the load path, but there's a lot of styling that goes into it.

I didn't contribute much to the bodywork, but he made some fairly large contributions to the cooling and to the frame.

The bodywork was styled by Tim Prentice, whose company 'Motonium' appears on the belly pan as a sponsor. I've got a great interview with Tim in the can, and I'll post it whenever I get around to transcribing it. (By 'in the can,' I mean it's already recorded, I don't mean that I was talking to him while he was in the can.)
You've been a stylist. You're not just a frame and chassis guy...

Yes, and I did some styling on this bike, before Tim came in. I went ahead and did three iterations of styling. But at the same time I was saying, Look I can do it, but I think you should get Prentice involved.

Mission had a previous commitment to the guy who designed the first Mission bike. So they had to go through a whole rationale as to why it should be styled by Tim and not that guy.

When saw it in the metal for the first time, were you really pleased?

Mission said to me, We want a world-class motorcycle. I looked at this situation and I knew that I could do a world-class chassis. I knew that Tim could do world-class bodywork. When Tim came in, I figured we could do a great bike. I didn't see the bodywork until the very end, because it went straight from CAD to being machined on these big mills that carve foam. It was late in the process when we finally looked at the bike and thought, it's a world-class motorcycle.

Is this the least-compromised real-world design [as opposed to a design exercise] that you've ever worked on?

Yeah, I think I would say that. It's really easy for people to jump in; for instance on the Indian project, they were constantly trying to turn it into a Harley Road King. I didn't want my bike to be another Road King, but [Indian's management] looked at it and said, the Road King's their biggest seller; it's an iconic design, make us one of those.

In the end, Mission really has been a good client for the artist in you, the engineer in you...

Yeah, and they're not just good clients, they're a good team.

Who did you work most closely with?

Jorah Wyler is the head of engineering, but he wasn't that active in terms of design. He has to work all these customer projects. Carl Johnson was the lead engineer, and this young Dutch guy Gerard Van Lahr came into the project. He's doing a thesis on motorcycle dynamics. He came to Mission as an intern and has been hired. There were others too, I don't want to leave other people out, but Carl was the main guy.

So for example when you were designing the frame, he'd be putting it into CAD?..

Yeah, and he did some FEA analysis. But we didn't do FEA on everything; it was a quick project and we didn't have a big engineering team.

How long did it take from start to finish?

I had the initial design a year ago September. Tim started talking to them a year ago October, but he didn't start serious work til much later. Because the company is doing other customer work, this project sometimes stopped for weeks at a time. If we'd been working straight through, it would have taken less than a year. It was a nine-month project that got stretched out to fifteen months.
