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.
Unique Engine Tuning
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.
A wide-ratio 6-speed transmission is used to insure the right gear is available for the wide variety of terrain found in cross-country racing.
Push button electric start makes starting the YZ250FX easy and convenient.
Light and Strong Aluminum Frame
An all-aluminum bilateral beam frame similar to the YZ250F provides strength, lightness and durability for race conditions, and comes standard 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.
270mm Front Brake
Large 270mm front disc brake coupled with high-performance pad material offers outstanding machine control and performance, with exceptional stopping power and controllability.
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.
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.
