Its' good you have riding experience, but street riding, especially in ANY traffic is a whole different animal - especially with a "crotch rocket ". I would recomend an ABATE riding course, its' not ment to teach how to ride, in the normal sense, but rather how to save your ass on todays roads! I would reccomend a different bike until I got street experience. But , the smallest ninja ( cc's ) for a starter, may be a big plus !
