I would get the 954rr. The overall rating is higher compared to the 1000rr, a zx-10, and a gsx-r 1000. I own a 2003 954rr and it has awesome power, yet it handles like a 600, a very good bike(very dependable). But do not disrespect it´s power....has alot more kick than a 600rr it will wheelie in 1st just by rolling on the throttle....not even halfway....get the 954rr...but be careful with it or you´ll be in the hospital
