2021 Yamaha YZ450FX

POWER, TUNED TO PERFECTION

Featuring a new, more powerful engine, an updated frame, and the smartphone Power Tuner app to dial-in the bike's settings to fit your style and conditions.

Features may include:

ENGINE

  • Rearward-Slanted Cylinder Design

The YZ450FX’s distinct rearward-slanted cylinder design—complete with rear exhaust and forward-mounted intake system—features a cylinder head that works with the frame geometry for optimized weight distribution. Inside, 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.

  • Electric Starter System

The YZ450FX features a compact electric starter system to minimize restart delays on track and add convenience everywhere else. Powered by a high-capacity and ultra-lightweight four-cell lithium-ion battery, the system adds minimal weight.

  • Yamaha Power Tuner App

The free of charge and industry-exclusive 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

  • 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 bump absorption, stiffness and rider feeling.

  • Compact Body and Seat Design

The YZ450FX features stylish bodywork from tip to tail, including a large 2.15 gallon mass-centralized fuel tank. The body design is narrow for more comfortable knee grip and control feeling while the narrower and lower seat gives the rider additional room to move aboard the machine.

  • 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.

ADDITIONAL

  • GNCC®-Focused Details

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

  • Adjustable Handlebar Mounts

The 4-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” handlebar is strong but lightweight.

  • Embedded Graphics

Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage.
