Ok I'm thinking about making the jump from my 98 kdx 220 to a new kx250f. I only race a few H/S a year and mainly trial ride but want more then the kdx has to offer. I am 6'0 190 without gear.Does this bike have enough "ummph" to pull me through the mud and hillclimbs,how much difference can I expect ? Any ex-kdxers out there have one ?
