Hey all, I am 13, 5'4" and 140lbs. i am looking into getting my first bike. I have ridden a bike ONCE before. I rode a 125 in a open field for about 5 min(never went out of second gear). I could not touch, so I don't know weather to get an 85 or will i out grow it quickly? I might consider a 250f but they are quite expensive for me. Any input is appreciated.
