I already have an xr 400, which I'm converting to dual sport. Now I'm trying to decide between the 250 or 426, which will be my play and race bike at the local tracks. Any opinions on why to go with one or the other would be appreciated. Those posts on the 426 don't sound very good. I'm 36 and will be running the old man class. I caught the dirt bike bug again after being out of it for 10 years.
