I'm 18 years old, 5'5 and around 135 lbs. I'm looking into buying a sport bike but I was wondering if anyone had any suggestions as to which bike(s) would be good for a new rider with my height/weight. I've looked at the ninja 500... According to what I've seen, the ninja 650 would be too much for me to handle. I've also seen some things about the sv650s and the gsx500f. Any input?
