Innovative Hare Scramble/GNCC® Engine Design
The YZ450FX™ shares the revolutionary rearward-slanted-cylinder design of the YZ450F™ that allows for a straight downdraft intake with a symmetrical port layout. In the YZ450FX, this engine delivers a controllable, torquey power character with strong top-end power tuned specifically for cross-country racing.

Bilateral Beam Aluminum Frame
A nearly identical bilateral beam frame that is found on the championship winning YZ450F is used on the YZ450FX. It places the engine, fuel tank and exhaust close to the center mass of the bike for extremely light and nimble handling character.

Advanced Fuel Injection
The YZ450F-based Keihin® 44mm throttle body fuel injection system is tuned for cross-country racing and ensures smooth throttle response and easy starting in nearly all conditions.

Cross Country-Specific Suspension
Industry-leading, YZ450F-derived KYB® spring-type forks with speed sensitive damping and a linkage-type, KYB® rear shock both feature fully adjustable settings designed specifically for cross country racing.

Cross Country Podium Ready
With a two gallon fuel tank, sealed O-ring chain, and an 18-inch rear wheel with XC racing tires, the YZ450FX is ready to win right out of the box.

Electric Starter System
The YZ450FX features an electric starter to help reduce rider fatigue along with a main switch-free electrical system for easier starting off.

GYTR® Power Tuner Ready
Accessory GYTR Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and race conditions in a matter of seconds with the push of a few buttons.

Real World Tough Features
Rugged plastic skid plate, quick-adjust clutch, aluminum handlebars and a side stand are standard for added rider convenience. Thanks to a WR-style fuel level sensor in the tank, the YZ450FX includes convenient fuel level and engine warning indicators on the handlebar.

Simplified Servicing
Redesigned air cleaner cover provides tool-less access to the air filter, positioned at the front of the bike to avoid roost from the rear wheel. A high-quality sealed O-ring chain is tough and durable.

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