450 EXC
The 450 EXC can justifiably claim to be the most widely ridden bike in enduro sport and a serial winner in the E2 World Championship. The top dog has been revamped and slimmed down in practically every aspect - from the frame to the electronic injection and the engine management system to the material selection. Above all, the new chassis and redesigned OHC engine widen the 450 EXC's lead over the competition by a further bike length. Extremely light, supremely agile and endless power - that's what winners look like.
