I could only think that maybe the ram air works a lil better when not in a draft perhaps.

Didn't he talk about having problems braking when in the draft of another bike? Not that he was close enough on the straight to be in the draft very often :-)

I was once told that the bikes with tail mounted exhaust try to set the exhaust height to the intake height of every other bike (including their own?) so any bike that comes up behind it is sucking in hot air and may lose 1 or 2 horse?

can someone help please, Crutchlow said the yamaha was faster with nothing in front of it but slower when behind traffic....what did he mean?, or why would that happen?..other than the obvious reason....

They cramp his style when in front or get in his way lol

Maybe he thinks he's faster with a clear run ??? He's learning being able to qualify well doesn't mean he will win.

All bikes have strengths and weaknesses. The Yamaha's strengths are negated by others being in front of it as they're slower where the Yamaha is fast, ie Honda's are slower through the middle of the corners.

Sorry to inturupt , have just had a chance to watch Quatar


MM on Rossi ,,

If he carries on like this it will be an exciting year

i think he means that his best speed was if he was not behind a bike which may hold him back in the corners..not so much an outright top speed thing?

And you can't deny that he's got good corner speed.

That's it. The Yamaha strength is corner speed, the Honda holds the Yamaha up in the corner then has the advantage in acceleration. Rossi got stuck behind Bradl for a time,
as did Crutchlow behind MM.

At least the difference isn't like the Yamaha to the Ducati in 2007 huh, Pritch ?
That little Austruckinfalian could pull heaps on the straight bits in his Championship year.

thats cos he had power to burn AND good mid corner speed

Well I don't know if that was the reason - but it would certainly be a nice side effect (if you were in front) don't know if it would be enough to counter the slipstream advantage.
Actually with the amount of effort that goes into streamling today is it better for a bike to be in clean air or disturbed air ? ( I know from yacht racing sailing into another boats "dirty" air had an obvious detrimental effect)
Also I remember reading that Ducati had some of the exhaust exiting up behind the rider to fill in the vacum behind them and help with aerodynamics. Do they still do that ?

[cmoore]

thank you for the responses.....corner speed advantage which is negated by the "slower" bikes in front...sound good to me....i suppose it is nice to know that after all these years of engine / bike refinement...they are not all the same....

..no the vacuum quit last year...

Can anyone give me a heads up to the better Grandstand at Phillip Island to watch the MotoGp? I cant make my mind up and was hoping someone had some first hand info. Cheers

Yep. Bass Straight without a doubt. I've been there many times and sat nearly everywhere. That did it for me. Turn three without a doubt is THE most exciting corner in GP racing IMO.
