I already ride a 90cc, and am looking for something bigger that i can trail ride and race on. Im 5 foot 7 and strong. oh, and im a girl :] i ride pretty rough for a girl. I was thinking about a yz250 2 stroke...is that too big? what size bike do most girls my age ride?

I want to get into racing dirt bikes. I already have experience racing go carts, but they got boring. I would be comfortable with having a powerband and not having the power spread out.

I'm 17 years old, weigh 150 lbs, and am 6' 2''.

I'm thinking about a 250 four stroke.
