2021 Yamaha YZ250FX

This Cross Country racer has all the features to win including the smartphone Power Tuner app that adjusts the bike's settings to fit your style and the track.

Features may include:

• Unique Engine Tuning

The revolutionary front-intake/rear-exhaust, high-performance liquid-cooled, 4-stroke, 4-valve, fuel-injected engine has been tuned for victories in the highly competitive GNCC® and Hare Scrambles race series. Intake and exhaust ports work with a higher compression piston for a wider spread of power without losing top-end performance.

• Yamaha Power Tuner App

Yamaha's free of charge and industry-exclusive 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 and Fuel 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. The fuel injection system uses 3D-mapped electronic control for the fuel and ignition timing that are optimized for cross country racing.

• Slim Bodywork

The compact bodywork eases the rider’s movement across the machine in tough terrain. The fuel tank provides 2.16 gallons of fuel with a larger fuel cap opening, and the graphics are embedded in the body moldings for long-lasting good looks.

• Light and Strong Aluminum Frame

An all-aluminum bilateral beam frame provides strength, lightness and durability for cross country racing conditions and comes standard with a rugged plastic skid plate.

• Advanced Suspension

Industry favorite KYB® fully adjustable spring-type forks with speed-sensitive damping and a KYB® rear shock feature a large 50mm piston. Both the fork and rear shock have been thoroughly tested and tuned specifically for cross country racing.

• Practical Touches

Quick-adjust clutch, wide 55mm platform foot pegs, four-position rubber-mounted handlebar clamps, aluminum handlebars and a side stand come standard for added rider convenience. The YZ250FX is also pre-wired for an optional radiator fan for the most grueling conditions.

• Easy Servicing

The air cleaner cover features toolless access to the air filter. Thanks to a WR®-style fuel level sensor in the tank, the YZ250FX includes a convenient fuel readout along with an engine warning indicator on the handlebar.

• Sealed O-ring Chain

High-quality O-ring chain is tough, durable and light.
