What is the differnce between an 02 YZ250F and an 01 YZ426F? I know the 426 will be heavier and have a lot more power. What what is the seat of the pants differnce? Ergos, cornering, jumping, that kind of stuff. I've heard the engine breaking is a minus, any specifics or is it not much different than my 250? I want the power, but not at the expence of ridablity.
