I used to have a Ninja 500 . Trust me the guys that bought a 250 were trading them or selling them after 3 to 6 months later. My 500 was ok for street riding, but after 6 months with highways or weekends in the hills and I wanted bigger. Probably 600 to start you out again and move up to 750 for tops if you never plan to do what you did in your ealier days.

Me, I will get my Hayabusa one day. Had the paperwork done one day just needed my first wife's signature. She said no because I would be riding it more than her. Go figure, she had to go and that day will come when I will have the chance again to get the Hayabusa.
