ENGINE The RMX450Z’s 449cc, four-stroke, four-valve, liquid-cooled, fuel-injected, DOHC power plant is based on the high-performance and reliable RM-Z450. Minimal differences as compared to the RM-Z450 motocross engine include a modified inlet tract and revised cam profiles to increase low- and mid-rpm power. The compact aluminum cylinder is finished with Suzuki Composite Electrochemical Material (SCEM) coating for durability, light weight, and efficient heat transfer. TRANSMISSION Strong five-speed transmission with wide gear ratios and primary/final drive ratios have been selected to suit various situations from steep trails to open terrain. CHASSIS The aluminum alloy twin-spar frame combines cast and extruded sections to achieve low weight with high rigidity and durability. RM-Z450-derived trail-ready suspension uses high-performance Showa forks with full adjustability. Aluminum link-style swingarm is descended from the RM-Z line and uses a fully adjustable Showa piggyback reservoir style rear shock.
