Had one of my most masochistic rides ever yesterday, and really missed my old YZ250 two stroke. Heat index here was 110 plus, and I'm a little out of shape, so those factors did contribute. Anyway, the terrain was brutally tight single track, and I felt like a fish out of water on the 426. The fact that the bike carries it's weight a little high, coupled with the "hitty" powerband just wore me out. Bottom of my right foot hurts like heck this morning from all the kicking to re-start. Bottom line is this- I know that the 250 two stroke is a much better tool for this type of riding. Swapped back onto my old 250 for a few minutes, and the thirty-something pounds less bike, as well as carrying the weight lower, was very apparent. Was a joy to ride. Does anyone have great success with the 426 in really tight woods, or am I just that out of shape and rusty?
