i've been riding/racing a fourwheler for a while now and its getting too expensive and bikes are a lot faster, so im trying to sell my quad to get a bike. ive riden bikes plenty of times, mostly a rm-125. i dont know what to get though. i wanted a 250f but now im having second thoughts. i want an mx bike for sure and i like 4 strokes and i want a really reliable bike. i dont know if its good to go straight to a 250f right away, i was thinking i should maybe get a 125 first or something, but i dont really have the money to keep selling and buying a bigger bike. oh yea and if it helps, im about 5'10" and 150lbs and would race the bike.
