IGNITION

The use of new materials raises the temperature resistance of the ignition and means greater stability at extreme temperatures. The new CDI box with optimized ignition timing provides increased per-formance and at the same time more steering lock on account of the smaller dimensions.

CLUTCH

The modified pressure cap ensures better oil supply and conse-quently cooling of the clutch, greater durability and more precise application.

450 EXC RACING

Top performance paired with loads of grunt packed into the best enduro chassis in the world: a combination that puts it right at the front in every comparison test. As on all Racing models an electric starter goes without saying.
