I just finished my safety riding course and now looking for a first bike. I was looking at a smaller bike like the ninja 250r as a first bike. However, I'm 6'2 and 220lbs. Is this bike going to be too small for me? Would it be too big of a jump to go to the ninja zx 6r? I am also taking the next level of safety riding courses too. You can never be too careful! Thanks!
