I have street bike experience but have never owned one. I want a sport bike and I have always been a fan of the Kawasakis. I don't know which bike to get though. Iv ridden the 250 ninja and liked it but I want a bigger bike. I want something I can gain more experience on while still having a well performing bike. I also want something that I can eventually modify and personalize. So what bike should I get? thanks for the help.
