Guys/Gals, ive got a problem...i currently have a 01 YZ426 and i like the bike...great power, good suspension, a bit on the heavy side but did i mention the great power?!? Anyways, ive been contemplating switching back to a 2 stroke or a newer 450(not the yz450 though as i do not like the 4 speed). I ride alot of motocross and sometimes trails, but when the going gets tight, the 426 just plain feels like a tank. The weight just tears me up on a track and im lucky if i can get 3-4 good laps without having to slow down and regain my lost strength....which leads to the conclusion that switching back to a two stroke might be a good thing in my favor as they seem to be quite a bit lighter. Ive been eyeballing an 03 CR 250 that they have at the dealer and also an 03 CR 450 that they have. Now, would the 450 be much of a difference between my 426?? My main concern is that im going to hop on the 250 and find out that it just doesnt cut it motor wise to my 426...has anyone recently made a similar switch, and if so, what kind of results are you getting??
