Based on the championship-winning YZ250F, a lightweight, compact chassis offers improved agility and handling feel in tight, technical terrain, along with better ergos and a more comfortable riding position for less fatigue over greater distances.
Yamaha’s revolutionary front-intake, rear-exhaust, liquid-cooled, DOHC 4-stroke power plant is paired to a wide ratio six-speed transmission for enhanced cross country performance, making the YZ250FX ready for enduro and cross country competitions straight out of the box.
Features
Rearward slanted engine
Advanced 250cc four-stroke engine features a high-spec piston, aggressive cam profiles and forward positioned intake cylinder head layout for a broad, useable powerband. An efficient down-draft intake path further boosts mid- to high-rpm engine performance.
Bilateral beam frame
Based on the competition-proven YZ250F, the bilateral beam frame provides just the right amount of strength and flex for the perfect balance of stability and cornering performance. The result is a better handling machine with lightweight feel and increased front wheel traction, allowing the rider to enter corners with greater confidence and more line choices.
Slim Bodywork
Ergonomics are optimised, with a slim, flat, compact body lending a razor thin feel and effortless body movement when shifting weight forward and back. The rider triangle is generous with sufficient space between the seat and footpegs.
Smartphone Power Tuner App
Yamaha Power Tuner App is even more user-friendly with intuitive Simple Tuning slide bar, helpful engine and suspension tuning guides, and additional features such as three-level selectable Traction Control System controlled through the Power Tuner App maintains ideal rear wheel traction.
Advanced Suspension
Yamaha’s class leading KYB suspension ensures maximum control and traction. Revised, fully adjustable KYB® coil springtype fork with speed-sensitive damping now includes hand-adjustable knob for toolless compression adjustment.
Cross County Features
With the electric starting system, a 7.95L fuel tank, rugged plastic skid plate, 18-inch rear wheel and XC racing tyres, the YZ250FX is ready to win right out of the box.
