Conquer Dirt

Cross country and enduro racing have been experiencing increased popularity and growth. Based on the legendary YZ250 two-stroke, the X model has been developed using all of Yamaha’s extensive two-stroke knowledge to produce a high-level cross country performer. The YZ250X is a lightweight, compact machine that is both exciting to ride and affordable to own and maintain.

/// Performance

    The YZ250X is a super light weight package that offers serious two-stroke power. The engineers modified the cylinder head, adjusted the compression ratio, revised the exhaust port timing and changed the gear ratios in the 5-speed transmission to better suit cross country racing (vs. the base YZ250). The YZ250X engine offers a good depth of power with an easy-to-use engine character.

 /// The Extras

    Cross-country-focused chassis features include softer suspension settings front and rear, an 18-inch rear wheel for more puncture resistance, an aluminum side stand and a fuel petcock that offers a reserve position for peace of mind (vs. YZ250).


    Key Features

    The YZ250X is based on the YZ250 2-stroke with the following additional features that enhance its competitiveness for cross country racing / riding.

      • combines with compact engine to provide an awesome power to weight ratio
      • obvious benefit of an aluminum frame is a significant weight reduction
      • Yamaha maintains the semi-double cradle design because it offers an excellent “rigidity balance” between lateral & torsional rigidity while offering controlled flex in the longitudinal plane

      • TCV enhances damping from mid to full stroke & improves bottoming characteristics
      • TCV offers more precise control throughout the full suspension stroke
      • TCV is located on the upside of the spring & its function is controlled by piston speed, not piston position, hence the term “Speed Sensitive System fork”.
    • Large “wrap-around” plastic fork protectors.
      • provide excellent protection from dirt, mud & stone chips
