Best 85cc

[Tommypx1]

I am 14 years old and am looking for a bike I am 5,0-5,1 I have a friend with an 07 yz 85 who is looking to sell it to me but I am worried about how it handles and its seat height. maybe a kawasaki honda suzuki or ktm I am also looking at the crf 150r. I want to do some racing and trail riding. I currently Ride a xr100 and love the way it handles on the track and on trails but it lacks a little power. any ideas thanks
