Based on the legendary 249cc YZ liquid-cooled reed-valve-inducted two-stroke engine, the YZ250X runs a revised compression ratio, exhaust port timing, Yamaha Power Valve System timing and a model-specific CDI unit.
To increase rider confidence in challenging cross country conditions, smoothly integrated body panels, narrow fuel tank design, slim shroud width and flat seat all combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for better control.
The exhaust expansion chamber is designed especially for the YZ250X, and is narrow for clearance on tight, technical trails, while still providing excellent exhaust efficiency.
A high performance braking system features large front pistons, a rigid caliper, a 270mm front rotor with a large pad contact area, and 240mm rear rotor - all combining to provide exceptional braking power and feel.
Smooth-shifting, five-speed, wide-ratio transmission ensures proper gearing from tight woods sections to wide-open fire roads.
A carefully engineered, advanced aluminium frame and swingarm give the YZ250X the famous handling proven by the championship winning YZ250 motocross machine on tracks around the world. Tips the scales at just 104kg with all fluids – which makes it lighter than a four-stroke.
Legendary YZ250 249cc liquid-cooled reed-valve-inducted two-stroke engine - focused on making a wide, controllable power character ideal for off road racing.
The fully adjustable KYB 48mm forks feature the Speed-Sensitive System which uses piston speed to control the damping force for super-precise handling, superb bump absorption and 300mm of suspension travel.
The YZ250X is focused on off-road competition and receives the same features as 125X such as 18-inch rear wheel, wide-ratio gearing - five speed in this case - standard side stand, sealed O-ring chain, reserve fuel petcock, headlight and scraper between the fork's dust and oil seal, all adding up to exciting performance.
A racy ‘gripper’ type seat and narrow fuel tank combine with a tapered aluminium handlebar and adjustable mounts to create greater freedom of movement and more comfortable ergonomics for riders.
Cross-country-spec Dunlop Geomax MX33 tyres front and rear are ready to head straight to the races. An 18-inch rear tyre has a tall sidewall for improve comfort and reduce pinch flats.
