well nvm i've pretty much decided on the kx125. mainly bc of the size
it's only 191 dry where the kdx is 222, so that's 30 pounds lighter. plus the ergonomics are much narrower and i'm not a real big guy, 5'5 or 6" 35 pounds and 15 years old. Plust with the woods we ride, i need the narrowness. my dad struggles witht he kdx on the tighter stuff a little still and he's, 5"7" 170 Pounds. so i think i'd have a hard time handling it through the tight turns and whoops, over the kx125. Plus i pretty much know the mileage. My friends friend rode a 46 mile trail on the wide, quad, trails pretty much wide open and made it. he ahas a 200 kx125.
