Well I wonder if there is any barrier on the pw 80 -03. My friend have got one and when I reach the top speed at the 3d gear the after a while the bike dosnt go any faster. I mean I´ve driven other PW´s but they go much faster. The top speed is about 75 KM/h the other pw´s are going about 90-100 KM/h. I think there is a barrier cause it doesnt go that fast when the motor revs up, maybe a rev barrier. Sorry for the bad english I speak I hope you can help me send me a message on semi_164@hotmail.com thx :)!
