Looking at the replacement options for the blown lump in my r1
can anyone confirm whether a 2007 engine will fit?
Doubt it’d be a straight swap. Fair more complex electronics as part of it.
Have you asked on the R1 forum?
More interesting would be trying to shoehorn the 09 motor in 
Then you’ll have the bike Yamaha should have built, and not the ugly heavy foooker it turned out to be 
Yes but it’s not exactly straightforward!
Star, cheers for the link rusty. I don’t have a bargepole long enough to touch that mess
ok 2006 engine it is
tbh it was only because I found a cheaper 07 engine that it was on the consider list. Defo not cheaper in the long run :pinch:
