I´m in the states here. you´ll have to convert from mph´s here but the official top speed rating from the factory says 162mph. THis is horseshit. before i decided to undertake my rebuild i was running only a yoshimura pipe for modification. I ran the thing to 175mph and was sitting around 8k-8.5krpm it´s kinda hard to be exact when you are going that fast. my opinion...easily a 200mph bike. look into a stage 1 jet kit from dynojet performance and go up a tooth in the rear sproket to get you to the top end. and keep that head on the tank lookin up!! ride safe
