2023 Yamaha YZ450FX

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:

TOP FEATURES
  • YZ450F-Based GNCC® & Hare Scrambles Focused Racer

Developed directly from its motocross brethren, the YZ450FX takes that competition-dominating formula and adds a number of cross country focused features and unique settings to make the ultimate four-stroke GNCC®/Woods racer.

  • High Performance Four-Stroke Engine

The compact, powerful YZ450FX engine includes all the same race-developed technologies of the class-defining YZ450F motocrosser, tuned for cross country performance. A host of go-fast innovations include steep valve angles, aggressive cam profiles, high-compression forged piston with low friction rings, high-flow intake and exhaust systems—all thoughtfully packaged to optimize mass centralization.

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.

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 Speed Sensitive System KYB® coil spring-type fork 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.

ADDITIONAL FEATURES
  • GNCC®-Focused Details

The YZ450FX includes a range of cross country specific upgrades compared to the YZ450F motocrosser including a composite engine guard, 18-inch rear wheel, sealed O-ring chain, fuel level warning indicator and a folding aluminum kickstand.

  • Adjustable Handlebar Mounts

Four-position adjustable handlebar clamps are rubber mounted to improve comfort, reduce handlebar vibration and allow riders to adjust the bar position, while the oversize 1-1/8-inch handlebar is strong but lightweight.
