Features

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.

Other Features

  • CROSS COUNTRY ERGONOMICS: A racy "gripper"-type seat and narrow fuel tank combined with a tapered aluminum handlebar and adjustable mounts create greater freedom of movement and more comfortable ergonomics for riders.
  • CROSS COUNTRY FEATURES: The YZ250X is focused on cross country competition with an 18-inch rear wheel, wide-ratio gearing, a standard side stand, sealed O-ring chain and a reserve fuel petcock.

Top Features

  • STUNNING TWO-STROKE POWER: TUNED FOR CROSS COUNTRY & HARE SCRAMBLES RACING: The YZ250X is optimized for the unique demands of Hare Scrambles and GNCC® racing. The YPVS™-equipped 249cc two-stroke engine is mated to a wide-ratio five-speed transmission for the ultimate cross country power plant.
  • ADVANCED MOTOCROSS-DERIVED CHASSIS: Ultra-lightweight YZ250-spec frame features carefully engineered combination of aluminum castings, forgings and extrusions for the perfect balance of rigidity and flex. The industry-leading fully adjustable KYB® speed sensitive spring-type front fork is matched with a fully adjustable high performance KYB® long-travel rear shock, both tested and tuned specifically for the needs of cross country racers.
  • GNCC®-SPECIFIC FEATURES: Cross country focused suspension setup and Dunlop® Geomax AT81 tires, 18-inch rear wheel, wide ratio transmission, narrow expansion chamber, sealed O-ring chain, a standard side stand and fuel tank petcock with reserve position are perfect for GNCC® racing.
  • RACING STYLE AND ERGONOMICS: The YZ250X carries the racing heritage of the YZ250 motocrosser with its aggressive styling from the front fender to the rear brake protector. Complete with an aluminum tapered handlebar, YZ-F-style foot pegs, gripper seat and Dunlop® Geomax AT81 tires, the YZ250X is competition-ready straight out of the crate.
  • 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.
