    Key Features

    For 2011, the RM-Z450 meets a stricter AMA noise limit (94db) while keeping smooth engine output.

    Suzuki's class-leading fuel-injection system uses technology from Suzuki's championship-winning models-the GSX-R motorcycles and the QuadRacer R450 ATV. The RM-Z450, the first motocross bike to ever use fuel injection, has won both outdoor championships as well as a Supercross championship.

    Engine Features

    The RM-Z450's 449cc four-stroke, liquid-cooled, DOHC, four-valve, fuel-injected engine was developed and refined to deliver phenomenal idle-to-redline thrust.
    The lightweight, battery-less, motocross-use electronic fuel injection system uses progressive throttle linkage for efficient power delivery.
    A 12-hole fuel injector delivers a fine fuel/air mist for efficient operation.

    The RM-Z450's aluminum cylinder is treated with Suzuki Composite Electrochemical Material (SCEM) coating, and was built for durability, light weight and efficient heat transfer.
    Transmission Features
    A 5-speed transmission provides extra flexibility, offering gear ratios suited for various terrains and conditions.
    The RM-Z450 has a link-type shifting system, which offers smooth transitions through the gears.
    Chassis Features

    The RM-Z450's slim chassis design makes for a comfortable riding position, opening up the cockpit to help allow the rider to actively take control of the machine.
    Class-leading 47mm Showa inverted forks provide optimum wheel travel and are compression- and rebound-damping adjustable.
    A Showa piggyback-reservoir rear shock with high/low-speed compression damping adjustment and rebound damping and spring preload adjustments. The rear shock, working through Suzuki's superlative rising-rate linkage system, provides 310mm of wheel travel, delivering maximum traction.

    The RM-Z450's twin-spar aluminum frame and swingarm was developed and refined for a highly optimized balance between rigidity and superb high-speed traction. The lightweight swingarm helps enhance terrain-traversing performance over bumps.
    Race-inspired disc rotors offer enhanced cooling performance and efficient mud slinging.
    A stylish two-tone radiator shrouds accentuate the RM-Z450's agile looks.
    The RM-Z450 comes with a gripper seat, with projected cross-shaped patterns on the top surface to provide additional grip.
