im asking this question for future reference because i don't actually ride street bikes but i plan it soon. when i do start riding it WILL be on a 250 and ill probly stay on that for a year and then upgrade to a 600 but what is a good bike once i am comfortable with riding on a 250? i already have motorbike experience because i ride dirtbikes and i know that road and dirtbike are completely different. ive been looking a the ninja zx 6r and the honda cbr600rr, which one is best to move onto once i become experienced?
