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. Based on the championship-winning YZ250F and boasting a wide range of cross-country features, the YZ250FX is a true “out-of-the-box” hare scramble/cross-country competition machine.
HIGH PERFORMANCE FOUR-STROKE ENGINE
The compact, powerful YZ250FX engine includes all the same race-developed technologies of the championship-winning YZ250F, tuned for cross country performance. Revised intake duct, intake port, exhaust camshaft profile, muffler and balancer weight position combine to further improve power and usability across the entire rev range.
SELECTABLE FUEL MAPS
Increasing the YZ250FX’s ability to tackle a wide range of riding environments, two optimized fuel injection maps—both of which can be loaded and tuned in the Yamaha Power Tuner App—are accessible through a handlebar-mounted map switch for on-the-fly adjustments to changing riding conditions. Pre-loaded maps include one for fast, aggressive high-traction conditions and one with a smoother engine character for extreme, low-traction conditions.

Pre-loaded maps include one for fast, aggressive high-traction conditions and one with a smoother engine character for extreme, low-traction conditions.
Competition-Ready Engine Performance
The revolutionary front-intake/rear-exhaust, liquid-cooled, fuel-injected, four-stroke engine has been developed 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.
Forward-Thinking Engine Design
Reversing the cylinder head while placing the intake forward and the exhaust to the rear allow for a straight shot, downdraft intake and straight exhaust port for maximized engine performance.

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.
Mass-Centralized Electric Starter System
The YZ250FX features a compact, centrally-mounted electric starter system to minimize restart delays mid-race and add convenience everywhere else. Powered by a high-capacity lightweight four-cell lithium-ion battery, the system adds minimal weight.
Six-Speed Gearbox
A six-speed transmission is used to ensure the right gear is available for the wide variety of terrain found in cross country racing. Updated gearing ratios and a heavy-duty, large-diameter clutch bring enhanced durability in the extreme conditions of a three-hour GNCC® race.
