Itchy to upgrade my current sportbike to the  superbike 1000cc kawasaki H2. Was looking at yamaha R1 too, but prefer the kawasaki H2.

Should i upgrade? Now my 250 kick feeling less and less already, already got used to it. Hungry for more power.

Owners please give me a review of both Kawasaki H2 and Yamaha R1. Thanks!
