Tilted like the Husaberg 450 or something less drastic?

I would hope that they wouldn't use the Husaberg layout. It seems counterproductive to me. Their design lowers the head maybe an inch and a half, while raising the much heavier crankshaft 4-5". The only possible benefit I see to the scheme is that the center of the engine package can be moved a little forward, but if that's what they were after, they beat themselves when they moved the crank back. I'm afraid I don't get it.

All these body work changes make me mad. Seems like there is only a few years that graphics companies focus on a particular year/model. Graphics for my 05 are already limited enough. If they change them again I'll have the same situation with my 08 in a few years.

We're a little off topic here but...

I think part of their reasoning was that it allowed them to run the fuel tank much lower by basically swapping the fuel tank and airbox positions. While it is a somewhat heavy bike (250+) it rides very, very light.

Good point. One does have to look at how the complete package plays out. I give them credit for thinking outside the paradigm, in any case.

I read all the posts on 2010 model and see 2 things that might be a negative.. The header is close to the fuel tank and the bottom of the seat... Hot A**...ouch.... boiling fuel?? Any thoughts??

Add to that the fact there would be little airflow around the exhaust and it will be hot but that can likely be taken care of with shiny, reflective, metal tape. I believe some of the factory teams already use this on the bottom of their tanks...

So, you guys are saying that Yamaha would run a ≤900 degree pipe under the gas tank with no shielding? Let me say that I highly doubt that.

They were trying to move the crank as close as possible to the center of the bike.

That I understand, but they also raised it a good 6 inches in the process, which, intuitively, seems like the wrong thing to do.

As long as the bike handles well, it's OK.

So.... after all these years.... intake in the front, exhaust out the rear. Airbox up high, fuel down low. Who'da thunk it!

Not that unusual for sport bikes. Evolution.

Wow it looks like they are doing some very creative or gutsy moves for this new bike. That tornado pipe thing is weird though:smirk:

Looks great. New 4 valve head.. wonder why the change? Also... kinda skeptical about the electronic shock, why the change there too? Obviously both are in theory better.. just looking for the justification.
