WR450F

The WR450F engine features a reverse cylinder head with a front facing air intake and rear-exiting exhaust. By increasing intake and exhaust efficiency, this innovative layout enhances the engine's linear torque feeling, and delivers deep reserves of highly controllable and easy-to-use power.

Developed from the design used on the YZ450F, the aluminium bilateral beam frame runs with sophisticated front and rear suspension systems that deliver light and agile handling performance. The highly versatile and easy to ride character of the new chassis complements the strong and controllable linear torque feeling of the new engine, enabling the WR450F rider to exploit the bike's full potential.

Starting the WR450F on a cold day - or restarting a hot engine - is made easy with the newly designed electric starter. A new auto-decompressor system cuts in when the electric start is activated for easy starting, and the air supply to the engine can be increased by 40% for reliable cold starting. The WR450F is no longer equipped with a kick-starter.

The WR450F uses the same forks as its motocross counterpart, but to ensure smoother low speed operation - combined with the ability to absorb harsh bumps - the WR-F model runs with dedicated enduro settings. Similarly, the YZ450F-based rear shock runs with revised settings that have been designed to handle the wide variety of low and high speed riding associated with enduro racing.

The WR450F is equipped with a full lighting kit, and to handle the extra demand on the electrical system, a high output ACM is fitted. The lightweight digital instruments include a multi-function display with an enduro computer that keeps the rider informed about their progress and distance covered - while a fuel level warning lets the rider know when it's time to refuel. The competition kit now includes a new Polisport headlight and lightweight Barkbusters.
