If you stroke the Crank 11.1 mm (0.437") the 600cc jumps to 750cc's. So now we can all have a big debate over buying another bike! Anyway, I was just curious how much additional stroke was needed to "obtain" 750...
Of course you need custom pistons made so they don't smack the cylinder head, that R6 header with the lager ID pipe becomes very useful, you need fuel management and bigger injectors/throttle bodies, some head porting and the air box mod now becomes meaningful. blah blah blah - list goes on...
Bene:
As the bore to stroke ratio nears square - the torque output goes up!
Stock:
Bore 65.5 mm, stroke 44.5 mm (2.58 × 1.75 in) X4 = 600cc
Stroked to 750:
Bore 65.5 mm, stroke 55.5 mm (2.58 × 2.187 in) X4 = 750cc
I'm guessing the crankcase has room to allow for such things with a little massaging if someone wanted to to such things...
/the end
