Key Features

  • Refined for Enduro
    Refined for Enduro

    Suzuki has made minimal modifications to the all-conquering RM-Z450’s potent four-valve, DOHC engine for the RMX450Z. This lightweight engine features a modified inlet tract along with revised cam profiles to increase low and mid-rpm power. Wider gear ratios in the 5-speed constant-mesh transmission that work with revised primary and final-drive ratios are ideally suited for a broad range of conditions, from scaling steep hill climbs to high-speed fire trails. The addition of a coolant reservoir tank increases on-trail reliability, while a relocated filler cap improves access. Because the bush can be a rocky place, a high impact engine protector plate is fitted.

  • State of the Art Chassis
    State of the Art Chassis

    Suzuki’s light and effective aluminium alloy twin-spar frame construction is used in the RMX450Z, employing both cast and extruded sections for the utmost benefits of both: low weight, high rigidity, and high durability. The RMX450Z’s aluminium alloy swingarm is derived from the RM-Z450’s to maintain ideal balance, while the rear suspension linkage benefits from reduced free play. Its geometry combines the RM-Z series’ renowned turning-on-rails abilities with optimised handling performance that all serious trail riders and enduro racers want.

  • Instruments You Need
    Instruments You Need

    A durable, ultra-compact enclosure houses a full-function instrument cluster on the RMX450Z—and can be configured for two modes, standard and sport. The sport mode simplifies the display so the rider can concentrate on terrain; it shows the timer, tripmeter, average speed and tyre-diameter correction. In the standard mode, the display also shows speed, time, two trip lengths, and voltage. An integrated tyre diameter calculator allows precise fine tuning for different tires to ensure accuracy of the speed and distance displays. The RMX450Z also features a low fuel level warning light for confident off-road riding anywhere you go.

  • Electric Start
    Electric Start

    The bush is no place to wear yourself out kick-starting a bike, so the RMX450Z comes with an electric starter, energised by a compact battery centrally located to reduce its influence on weight distribution and balance of the bike. To charge the battery and power the RMX450Z’s lights, a larger magneto-generator is fitted. It’s a win-win situation.


  • A larger magneto-generator is fitted to charge the battery and power the lights.
  • Advanced fuel-injection system makes for extra-smooth power delivery, high fuel efficiency, superb reliability and reduced emissions.
  • The airbox features a hinged lid for quick air-filter maintenance and better protection from dust.
  • RM-Z450-derived, trail-ready suspension, using high-performance Showa forks and Showa piggyback-reservoir style rear shock.
  • Motocross-developed seat, slim bodywork and low-profile aluminium-alloy fuel tank together compose a comfortable, ergonomical riding position.
