I use to stunt an 01 gsxr 1000 it had lots of power, I got it up to 172mph before I shut it down. I have never owned an R1 but they look awesome. I also love the new cbr 1000. I think it depends on what you like? The sound of a 2 cylinder, or 4?? I stunt a cbr 929 now and love the brakes, power, everything, although it is way under power compaired to the gixxer 1k.
gixxer
929
I have blown up both the gixxer 1k, and 929 motor, if that helps.
