i own a 1994 cbr600fr which i believe to be a 150mph bike, so why can´t i get anymore than 120? the bike is standard and as far as i know hasnn´t been modified in anyway. the one thing i will say about it is i think it´s an import because it has Kph clocks on it.As far as i know the japanese didn´t restrict the 600´s can you please help. many thanx
