2022 Yamaha YZ250X

Chassis / Suspension

• Industry-Leading KYB® Fork: The industry-leading, fully adjustable KYB® spring-type fork with speed-sensitive damping uses piston speed to control the damping force for super-precise handling and a smooth ride. With minimal wasted stroke or abrupt shocks for the rider, this bike is tuned for the demands of cross country racing.
• SMOOTH KYB® SHOCK: Fully adjustable KYB® rear shock features 12.4 inches of travel, separate adjusters for high- and low-speed compression damping and a full lock oil rebound system for increased comfort, control and fantastic rear wheel traction in challenging conditions.
• YZ250-BASED FRAME: A carefully engineered aluminum frame and swingarm give the YZ250X the famous handling proven by the championship-winning YZ motocross riders on tracks around the world.
• LIGHTWEIGHT SUBFRAME: Removable aluminum rear subframe is constructed of square-section tubing for reduced weight.
• 270MM FRONT BRAKE: Large 270mm front rotor coupled with high performance pad material offer excellent machine control and performance, with exceptional stopping power and controllability.
• ENDURO-SPECIFIC WHEELS AND TIRES: Cross country-spec Dunlop® Geomax AT81 tires are competition-ready, while the 18-inch rear tire has a taller sidewall to improve comfort and reduce pinch flats.

Engine

• GNCC®-TUNED YZ250 POWER: Based on the legendary YZ250 249cc liquid-cooled reed-valve-inducted two-stroke engine, the YZ250X utilizes a revised compression ratio, exhaust port timing, revised Yamaha Power Valve System (YPVS™) timing and a model-specific CDI unit—all focused on creating a wide, controllable power character ideal for cross country racing.
• REVISED POWER VALVE: The YZ250X features the patented Yamaha Power Valve System—with broader opening timing compared to the YZ250 for smoother power—to combine bottom-end acceleration with strong mid-range and top-end.
• NARROW EXHAUST PIPE: Unique compact exhaust expansion chamber is designed especially for the YZ250X to improve both horizontal and vertical clearance on tight, technical trails while still providing excellent exhaust efficiency.
• ADVANCED CARBURETOR: The 38mm Hitachi Astemo® Keihin PWK carburetor with throttle position sensor provides precise fuel/air mixing and crisp throttle response throughout the powerband.
• RACING INTAKE SYSTEM: Specially designed carbon fiber reed-valve petals improve throttle response and engine performance across the entire rpm range.
• WIDE-RATIO FIVE-SPEED TRANSMISSION: Smooth-shifting wide-ratio transmission ensures proper gearing from tight woods to wide-open fire roads.
• YZ250 COOLING SYSTEM: Large-capacity radiator features a ten-row core with four louvers for maximum cooling efficiency.
• DIGITAL IGNITION: Digital CDI ignition system delivers precise spark for faster, stronger response anywhere in the powerband, specifically tuned for the needs of the YZ250X.
