I am 18 and I would like to start racing. I have never raced before but it looks like a lot of fun. I am about 6 foot and 140 lbs. I don't want a 2-stoke tho and I don't want a dirt-bike that would have to much power that i couldn't handle. I have a Honda CRF230F right now, but that isn't exactly a good race bike. Any suggestions?
