New 2022 Yamaha YZ450FX Dirt Bike Motorcycle

POWER, TUNED TO PERFECTION

Whether cutting through tight technical trails or blazing across the wide open desert, the class-defining YZ450FX takes off-road performance to new levels.

Features may include:

ENGINE

• Rearward-Slanted Cylinder Design

The YZ450FX’s distinct rearward-slanted cylinder design—complete with rear exhaust and forward-mounted down-draft intake system—features a cylinder head that works with the frame geometry for optimized weight distribution. Internally, the engine features a straight intake tract, aggressive cam profiles, a high-compression “box bridge” piston design with DLC-coated piston pin and more. Finally, the YZ450FX features specific ECU settings to suit the needs of cross country riders.

• Innovative Yamaha Power Tuner App

The free-of-charge Yamaha Power Tuner app brings the power of the GYTR® Power Tuner to your iOS® or Android® device. Using wireless connectivity to talk to the bike’s onboard CAN-bus network, the app allows owners to adjust air/fuel mixture and ignition timing maps to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more.

• Adjustable Engine Mapping

A handlebar-mounted map switch allows the rider to quickly select between preloaded engine maps—loaded and configured in the Power Tuner app—to account for changing riding conditions. Map 1 provides more responsive, quicker revving engine characteristics while Map 2 provides smoother response, slower revving characteristics for when traction is limited.

CHASSIS/SUSPENSION

• Advanced Bilateral Aluminum Frame

The upper frame bracing provides rigidity and durability while rear frame spars and cross country-tuned engine mounts centralize mass for the best possible balance of impact absorption, stiffness and rider feeling.

• Class-Leading Suspension

The industry-leading, fully adjustable KYB® coil spring-type fork with speed sensitive damping provides exceptional balance between handling and bump absorption for race-winning handling performance. The linkage type rear suspension uses a KYB® shock with specially-tuned damping characteristics to match the YZ450FX chassis with both front and rear system settings for optimal GNCC® performance.

• 270mm Front Brake

Large 270mm front rotor coupled with aggressive pad material offer excellent braking performance and feel with exceptional stopping power and controllability.
