The 2007 MY of the YZ450F carries on the new performance standards introduced by the previous year model. What started out as a new engine in a new chassis has been revised and tweaked for even better grunt and more precise power management. The 2007 MY got a new exhaust cam, revised fuel delivery and a new exhaust system.
Several brake and suspension elements have been redesigned for weight loss, while the rear monoshock was optimized for better response to demanding situations. The clutch now has a stronger pressure plate, while fewer steel plates reduce heat build-up and provide a lighter lever pull.
