Descended from the Championship winning RM-Z450, the first motocross bike to offer high-performance Suzuki fuel injection, the RMX450Z is a serious off-road bike for serious trail riders. Its powerful and torquey 449cm3, liquid-cooled, four-stroke engine shares all core technology with Suzuki’s winning open-class motocrosser. Its frame, suspension and bodywork are all nearly identical to the RM-Z450’s—maintaining that model’s slim, aggressive styling. Only changes to make the RMX450Z a superior trail machine have been made—maximum performance – no compromises.
Derived from the RM-Z450, the RMX450Z’s trail ready suspension features the same phenomenal action as the race bike.
The RMX450Z suspension utilizes high performance rebound and compression damping adjustable Showa forks combined with a Showa piggyback reservoir style rear shock featuring two-way adjustable compression damping with adjustable rebound damping and preload adjustments. Spring rates have been optimized for off-road riding. Every aspect of the RMX450Z’s performance envelope has been carefully considered for serious off-road riding without compromising a millimeter of quality.
Suzuki pioneered fuel injection for motocrossers, and he RMX450Z shares all key technologies with he stunning RM-Z450. Fuel injection improves fuel fficiency, throttle response and reduces missions, allowing the RMX450Z to be “green ticker” eligible in the state of California. On he every trail in the world, the RMX450Z’s uel injection provides unmatched moothness of power delivery and rail-ready reliability thanks to a KEIHIN throttle body with progressive linkage.
This advanced fuel injection system also eliminates the need for re-jetting at higher elevations. To best suit the RMX450Z to life on the trail, the airbox features a hinged lid for quick air-filter maintenance and better protection from dust. Suzuki’s vast experience with motorcycle fuel injection both on and off-road help make this among the best systems available
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 tire-diameter correction. In the standard mode, the display also shows speed, time, two trip lengths, and voltage. An integrated tire 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.
The trail is no place to wear yourself out kick-starting a bike, so the RMX450Z comes with an electric starter, energized 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.
Sit on an RM-Z450. Now go sit on the new RMX450Z. Feels just about the same, right? That’s right. With an ideal riding position resulting from the motocross-developed seat, slim bodywork and low-profile aluminum alloy fuel tank, the RMX450Z allows the rider to concentrate on the terrain. A comfortable rider is a fast rider
