Well I rode all the bikes listed. My 2002 yz426 easily beat the KTM in all catagories. Speed accelleration, climbing, snap, and looks etc. Then comes my drz400E(for sale)which climbs alot better, faster, and handling. Then comes my 1982 XR80 which I had when I was 6. Finally I realized the KTM400 has no features you would want except the hydrolic cluch.
