Its an 1043ccm engine, a new aluframe.. But the ZX-9R Engine can be bored to this size..
But kawa says its a "quick-revving" engine, but im not sure its the ZX-10R engine, hope so..
The 2010 ZX-10R have a new exhaust(just cosmetic), better gearbox, longer wires to improve throttle control, and a better Öhlins steering damper..
