ok, well i know somone that has a wr250, those babys fly!!! and i hear those pull up really easy too so if u ride wheelies u wont run out of power very quick. those have the preasure release thinger so i hear those start easy if thats what u want. and in the feilds u might like 15 inches of ground clearence. and if u are into jumpin those jump too.....well i recommend the wr250 cuz those start easy and the ground clearence plus u wont run out of power and u can ride wheelies good, later
