So, what engine do you reckon its got?
 

Looks like one trick piece of kit! Gizza go!

I remember seeing an article in one mag where yamaha had used the R1 engine in a snow mobile:D the engine was turned around 180 degrees so the zorst was straight out the back, must be quite fast to:D:D

Yeah probably an R1 lump, they use them in their jetski's now, so it kind of figures, see Edwards behind Rossi there...

R1 motor in some shape or form.

Rossi might want to stay of the slopes if MCN can be believed tho' some solicitor is suing him after he got clobbered on the slopes by Il doctore??

Ray.
