True, a friend of mine has a GSXR and his bike is probably a tiny bit faster than mine... however he says that the GSXR is like hot poker while mine is much smoother and deceptively quick.
No way am I expecting more, it'd be apples to grapes. My gixxer will flat out fly, I'm too old for that, haha
You won't be disappointed then. Overall, in my opinion, the motor is better than the Gixxer's. I'd still consider going +2 on the rear to close the gears a little bit as they are quite high with the stock gearing.
... or down one in the front, which I prefer, thanks for the tip. That'll also give me a reason to buy a speedohealer.
