Best of all, it's free-of-charge.

Advanced Aluminum Bilateral Beam Frame

The advanced aluminum bilateral beam frame with YZ450FX-specific engine mounts provides just the right amount of strength and flex for the perfect balance of straight-line stability and cornering performance. The result is a better handling machine with lighter feel, more agility and increased traction, allowing the rider to tackle tight, technical courses with greater confidence.

World renowned suspension performance straight out of the box. High-spec fully adjustable Speed Sensitive System KYB® coil spring-type fork provides exceptional bump absorption, and now features toolless compression clickers for easy adjustment and fork covers to help prevent debris damage. The linkage-type rear suspension features a KYB® shock with cross-country focused damping characteristics to match the YZ450FX's refined chassis.
