richi

Hi im Richi a aussie, i live in the NT. im a tyre fitter and when im not fitting tyres im riding my bike. I ride a kawasaki GPX250 "98". ilove riding in the NT due to the fact theres no speed limit once u get out of town. but theres one prob my GPX is only good for 160km/h.... I need a bigger bike if not bigger i need to know wat else i can do to the one i have now.
