Bought my ´94 cbr while I was in Iraq and have been doing a little riding on it since I got back.... The bike I have tops out at about 145 but not in the red on the tac.... Am thinking about putting a bigger rear sprocket to give it more torque.... I am in Colorado and I think it needs tuned to this altitude because it seems to lack some power.... New pistons and rings probably wouldn´t hurt along with a professional tune up.... As it is it lacks the power to pull any wheelies without really using some aggressive throttle and clutch control.... I really don´t know how this bike would have performed new.... I have to say I expected a little more power though.... All in all I have had fun riding it....
