A Formula For Success: We build and race FACTORY EDITIONS. Championship winning bikes, like this one. Thanks to its compact SOHC (single overhead camshaft) engine delivering explosive but controllable power, it is the weapon of choice for Red Bull KTM Factory Teams around the world. A lightweight chassis and a slim bodywork put the 450 SX-F FACTORY EDITION out front of the competition. A long list of special equipment such as a factory installed holeshot device, a floating front brake rotor and a new slip-on AKRAPOVIČ muffler add to the arsenal that raises this limited edition model to a level that cannot be rivaled. The FACTORY EDITION is a formula for success.
