QuoteBut Rossi made clear that Ducati isn't abandoning its stressed-member concept

If I were losing that badly with that much talent, my member would be stressed too...maybe they need a Hero Member...

At Aragon, Nicky was quoted as saying "My engines wouldn't work in that chassis." , referring to Rossi's GP11.1Al.

I like the Titanic/deck chairs comment at the end. Very appropriate. [laugh] [roll]

I have flying honey badgers and I'm not afraid to use them!

The fact that flame throwers exist is proof that someone somewhere said "I'd sure like to set those people over there on fire but I'm just not close enough to get the job done."

CONFIDENCE: the feeling you have right before you understand the situation.

Duc shuts down their WSBK team (yeah, yeah... I know Checa is the de facto "team"), pays Rossi a boat load of $$$ and this is all they can come up with? [bang] Who's actually in charge of this mess? It's like watching a plane spiral out of control and/or watching a boat sink. Take your pick. Sad. :P

good text by Kevin Cameron (as usual).


Cameron does a nice job of explaining the role that chassis flex plays in stability in his (1998) book Sportbike Performance Handbook (see Chapter 14), and touches on the strengths and limitations some manufacturers dealt with.  Although it's ~fifteen years old, the physics of chassis stability have not changed.

I say for sheetz and giggles Rossi should throw a leg over a trellis framed GP11 and see what happens....

How exactly does that thing work?

forks are solid pieces

the yoke has a single shock



basically adapts the rear single shock design to the front.

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the airâ€"these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

rossi to test new al frame at jerez... differing information on whether it will be twin spar or the "frameless" style though.

The concept is that the fork lowers are built to flex side to side but not forward to back. The flex is tunable and comes into play when the bike is leant all the way over. The rider still has a direct connection from the bars to the tire. I can't imagine why people wouldn't consider this option.

I understand the reasoning behind the change away from the steel trellis (airbox volume), but they seemed to be winning then despite, so...
