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-created 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 track and weather conditions.

Advanced Fuel Injection 
The engine breathes through a 44mm Mikuni® throttle body fed by a high pressure electric pump to ensure optimum fuel atomization and power for a wide range of riding conditions.

Robust Transmission and Clutch 
The YZF450FX’s wide-ratio 5-speed transmission enhances cross country performance for more flexible gearing selection in open terrain.

CHASSIS

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 8.2-litre 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 cross-country race performance.

270 mm Front Brake 
Large 270 mm front disc brake coupled with aggressive pad material offer outstanding braking performance and machine control with exceptional stopping power and controllability.

Cross Country Wheels and Tires 
The YZ450FX features enduro-specific tires for the ideal balance of traction and durability, complete with an 18-inch rear wheel. Each wheel’s cross-sectional profile is computer-designed to shave valuable weight without sacrificing durability, too.

ADDITIONAL FEATURES

XC-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 
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-inch 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.
