Ultimate Performance Two-Stroke

The YZ250 offers pure performance and full throttle adrenaline in a lightweight and reliable two stroke machine.

Exhilarating Two-Stroke Power

The 249cc liquid-cooled reed-valve-inducted two-stroke engine is lightweight, compact and fun featuring the patented Yamaha Power Valve System (YPVS) for crisp response and an incredibly wide, hard-hitting powerband.

Class-Leading KYB® Suspension

The YZ250's renowned suspension performance offers unmatched levels of control, capability and comfort. The class-leading Speed Sensitive System 48mm inverted KYB fork includes a leaf spring in the mid-speed valve for more precise damping and increased performance. The fully adjustable KYB rear shock features reduced-friction Kashima Coat internals, separate adjusters for high- and low-speed compression damping, and a full lock oil rebound system for enhanced comfort. It all adds up to class-defining suspension and handling characteristics.

Aggressive YZ Styling

Race-inspired styling-from the sharp embedded graphics, to the aggressive bodywork including front and rear fenders, blacked-out radiator shrouds and number plates, to the smaller details like fork guards, rear brake disc and caliper protectors, and wide foot pegs-spotlights the YZ250's extensive two-stroke racing pedigree from every angle.

Confidence-Inspiring Ergonomics

A carefully considered ergonomic design includes a flatter seat, narrow fuel tank, smoothly integrated body panels and slim shroud width to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for increased control and confidence.

Lightweight 21-inch front and 19-inch rear Excel® rims provide exceptional durability and a premium look. They come paired with Dunlop Geomax MX33 tires offering race-developed performance for a wide range of terrain.
