2019 Yamaha YZ250FX

With electric start, an 18-inch wheel, a wide ratio 6-speed gear box, the YZ250FX is a powerfully-built, lightweight machine engineered for cross-country victory.

• Engine

The revolutionary, rearward slanted, high-performance liquid-cooled, 4-stroke, 4-valve, fuel-injected engine has been tuned to challenge for race victories in the highly competitive GNCC® and Hare Scrambles race series.

The position of the engine moves the rotational mass of the cams towards the center of the bike which allows for a straight shot, down draft intake and straight exhaust port for maximized engine performance. Additional, this layout keeps the air box up high, out of dust and mud/water.

The fuel injection system uses 3D mapped electronic control for the fuel and ignition timing that are optimized for cross-country racing.

• Chassis/Suspension

An all-aluminum bilateral beam frame similar to the YZ250F provides strength, lightness and durability for race conditions, and comes stadard with a rugged plastic skid plate.

Industry favorite KYB® fully adjustable spring-type forks with speed sensitive damping and Kashima Coat™ and a KYB® rear shock, also with Kashima Coat™ and featuring a large 50mm piston. Both the fork and rear shock are tuned specifically for cross country racing, with fork seals designed for improved durability in harsh conditions.

Special cross-country racing Dunlop® AT81 tires are used to maximize traction while delivering excellent wear.

• Additional

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.

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

The air cleaner cover helps prevent contact with the quick-release quarter-turn Dzus® air box fasteners for tool-less access to the air filter. Thanks to a WR®-style fuel level sensor in the tank, the YZ250FX includes a convenient fuel level along with an engine warning indicator on the handlebar.
