Description

The high-flying, high-paced action of motocross is not for everyone. As a result, the slightly less intense world of cross country / hare scramble racing is a popular alternative. The YZ250FX is a cross-country-focused model with the performance potential of the YZ250F. If you are serious about winning, the YZ250FX could be the machine for you.



Performance: The YZ250FX uses the reversed-cylinder, rearward-slanted engine from the previous-gen YZ250F with modified fuel injection settings, electric start and a 6-speed transmission.



The Extras: Featuring a KYB speed-sensitive fork and fully adjustable KYB rear shock, the FX uses the same suspension as its MX cousin with softer settings and slightly more rear wheel travel. Also included is a lightweight aluminum side stand, adjustable handlebar and an 18-inch rear wheel. .

Engine Features
  • "Reversed" liquid-cooled, 250 cc, DOHC, 4-valve (titanium), single-cylinder engine with fuel injection. The engine has been tuned for excellent rideability and controllability and delivers a broad, easy-to-use powerband with excellent power characteristics throughout the rev range. 2018 model changes improve power delivery in both low-to-mid and mid-to-top-end performance: rearward slant moves a significant amount of rotating weight toward the centre of the chassis
    • rearward-slanted cylinder centralizes mass for excellent handling and a light, agile feel
  • Rearward-slanted, reversed cylinder design: rearward slant moves a significant amount of rotating weight toward the centre of the chassis
    • rearward-slanted cylinder centralizes mass for excellent handling and a light, agile feel
  • "Reversed" engine design (FI system is front-mounted, exhaust exits from rear of cylinder): forward-mounted FI provides straight intake path into the cylinder and provides optimum fuel/ air filling and flow for excellent power; front mounted intake design keeps fuel cooler since engine heat has less effect on incoming fuel (cooler fuel is more dense and increases power); design also helps centralize mass for light, agile handling
  • Electric start with auto decompression system. Unit can be re-started in any gear: there is no main ignition switch on this model; electric start button (RHS handlebar) activates the entire electrical system; kill switch (LHS handlebar), if held for a few seconds, shuts down entire electrical system; removal of kick starter and related gears etc. reduces weight
