hi jim, you didn`t say how old you are and if you are of youth age and want to enter trials you will be limited to 125cc, ( correct me if i`m wrong anybody) i have only been riding since august last year and started off on a gasgas 280 it was a bit to powerful so i bought a beta 250 (03) my riding has improved in a big way, the bike is so much easier to ride with smoother power delivery and feels more stable.
good luck, gary
