Now Vale is out and broken do people think the bike seems more sensitive to cold tyres. Almost all the riders in recent history have had mega highsides on coldies, Jorge at Laguna, Spies in France, Rossi on Saturday and Toseland in Qatar during testing last year.

Comments?

Can't say - haven't ridden one.

I'd suspect the traction control (or lack thereof)

 

[Blazzer]

sif noobs. wait till the tyres warm up.

Wasn't Rossi complaining about how much traction control there is on modern MotoGP bikes?

Think Jeremy said that it was just cold tires in a sector that he was slow at and was pushing it.

I'm guessing that the teams haven't spent enough time mapping cold/new tyres into the traction control system which makes sense really, you're not on them for long, but I think that its starting to show that it does matter a bit more than they're paying it for.

EDIT: Just watched the Rossi crash video and it looks like his anti lockup system went on a bit of a mental holiday and he lost the rear in a big way.

Anti lockup? I haven't watched it recently but it looked like he was on the gas when it came round on him..

 

[Hessian]

Rossi a newb They cover that stuff in QRIDE

To me it looked like he was still washing off speed during the tip in, but I've only looked at it once or twice in fairly grainy youtube.

The bikes all have throttle lifters or the like to eliminate compression lockup on turn entry. If it wasn't tuned correctly (probably uses traction control mapping) or completely failed then he'd end up with shitloads more compression braking than he was expecting and the back would come around on him.

He was on the gas. After his last apex it's pretty much all open throttle for the next 3 turns.

Burgess said he was 10 seconds slower than normal in the previous sector which cooled off the tyre a little. He then applied too much throttle for the velocity he was carrying and it ejected him.

oh well, traction control failure then

Rossi himself said it was his fault in an interview
He was just out of the pits, and he slowed down coz Pedo or Dovi and somebody else were on a good lap.
he gave it too much throttle and went on his ear as the tyres weren't up to temperature
unfortunate landing

Holy sweet jesus you mean crashes are caused by rider error and not failure of electronics?!

Nah that couldnt happen

Burgess was quoted as saying..... And I quote,
