I looked at a used CRF450R and felt right at home on the bike it was awesome but i dont know if i could handle the power of a 450 im 5'5 150lbs 14 years old nd i have alot of expierience on a ttr125 and some on a yz250 and i did ok on the 250 it was a little to tall for me and i do trail riding. whats your opinion of me riding a CRF450R maybe with a flywheel weight do ya think i could handle it or what?
