Key Features

  • alt

    Sharp bodywork and bold graphics

    The YZ250 2-stroke features modern bodywork and graphics that give a light and fresh look. The fenders and fork protectors give a sharp image, while the side covers and seat cover underline the fresh look – and to underline the ‘factory bike’ style we’ve fitted the air scoops with new graphics.

    YZ-F type 48mm upside down forks

    The 48mm upside down front forks are similar to the design used on our YZ-F 4-strokes, and feature a separate air/oil system that prevents air from entering the cartridge for more stable damping. The forks run with special YZ250-specific settings, and give a light and agile handling characteristic.

    Monocross rear suspension system

    The YZ250 is equipped with a smooth Monocross rear suspension system consisting of a swingarm, shock and linkage taken from the YZ-F 4-stroke bikes. This system offers outstanding shock absorption characteristics together with good traction for class-leading performance.

    Wide footrests

    The YZ250 2-stroke benefits from a range of features that have come straight from our latest YZ-F 4-stroke models. The wide footrests give additional support of controllability during aggressive riding – and there’s also an modern clutch adjuster for easy tool-free adjustments to cable slack.

    250cc 2-stroke engine with YPVS

    The explosive power and strong torque produced by the 249cc liquid-cooled 2-stroke engine is what makes the YZ250 so popular with everyone from hardcore dirt riders through to freestylers and fun riders. Fed by a 38mm carburetor and featuring our torque-boosting YPVS, this 5-speed powerplant responds instantly to rider input.

    Lightweight semi-double cradle aluminium frame

    The YZ250 features a compact and lightweight semi-double cradle aluminum frame that offers a good balance of rigidity for immense strength with low weight. Together with the Monocross rear suspension system, the aluminium chassis helps to keep wet weight down to just 103kg for outstanding agility.
