KTM 450 SX-F

KTM's profilation of this bike

Not a bike but a racing machine which is the main contender on all tracks. As well as the revolutionary engine, this bike also has an extremely light chassis and trend-setting running gear. For 2009, the 450 SX-F (like the 250 SX-F) has been trimmed at the factory specifically for MX1 series wins: with huge numbers of great PowerParts!
