my close friend who owns a 600 RR was pretty slow, and i would borrow it from time to time, and you could feel the difference, only thing i liked better about it was that i sat up and the bars where a little up more, wasnt as aggresive for daily riding
i would pull on him by 1 to 2 cars every time, same on other 600 RR, but i did get my shit straight up handed to me by a 01 F4I by about 2 and a half cars.
