Well after having my kfx for a few monthes I finally took it riding. Where I live I mainly just get to ride on the country roads and was thinking of selling it for something with a clutch. But yesterday me and a few friends hit some trails, couple brutes and a kfx 450. Ill have to say everyone was pretty impressed with the way mine performed on the muddy trails. If it didnt bottom out it went. I climbed a bunch of rutted out muddy hills covered on roots and rocks, that the 450 didnt. I think its all in the auto trans. Most of the smaller banks that were around 25 ft tall that get steeper as you go up the auto is so much more controlable at the top.
