– 2003 Yamaha WR450F Review

2003 Yamaha WR450F

Bigger Bark. All New Spark…

Introducing the all-new WR450F. Our big-bore off-road rocket blasts off into 2003 with more power, significantly reduced weight, a stronger chassis, smoother suspension, more aggressive bodywork, and push-button electric start. But the magic little trigger is merely the icing on this incredible new trail missile. From its larger 449cc four-stroke powerplant and stiffer, lighter-weight frame and swingarm to stronger brakes and countless other upgrades, this totally new off-road weapon now packs an even mightier one-two punch of broader, trail-taming power and sharper, suppler handling.
