I am a new rider and I am thinking of purchasing a sports bike in the 125cc to 250cc range. I am 6'3'', 185lbs. and concerned that I'm too tall for a bike of this size.
iam 6'2 and 198lbs.i ride my buddys ninja 250cc.and let him ride my zx-6.the 250 feels just right and i like how it handles the turns(light and easy to corner) i also like how the 500cc ninja feels.sits almost as good as my 600cc.so no your not to big for a ninja 250 but i think you would be to big for a 125cc.
