I have found through my owning of a new 02 kx 250 that it had no bottom end and a hard hitting mid and topend, almost uncontrollable wheel spin, not good for woods. I now have an 07 YZ 250. compared to the last 4, 2 strokes ive owned,99 cr 125, 98 YZ 250, 06 Kx 100, and 02 KX250, the 07 YZ 250 is a dream to ride, the suspension fit and finish and handling is superb. Lacks a little on topend but I really only ride trails and am uncatchable in the woods where topend is not necesary, It handles like its on a rail, Yamaha is still doing Research and Development on 2 strokes and the 07 YZ 250 proves it, I would consider it to probably be the very best 2 stroke Ive ever ridden, and am blessed enough to own. :nod:
