2011 KTM 450 SX-F

Does anybody need the brutal power of a 450 SX-F? Well, we wouldn't say "really need" in the sense of "can't do without". However, we do completely understand that some people really want this brute force. Because taking a ride on a cannonball is potentially somewhat addictive. Who is better placed to understand that than we are? Anyway, we have practically redesigned the 450 SX-F as well, with new bodywork and new linkage-suspension. And we have even managed to worm a bit more power out of the carburetted engine.
