2018 Suzuki RMX450Z

Powerful, torquey fuel-injected 449cc engine. Slim, aggressively styled chassis and bodywork. Electric starter. Full-function, two-mode instrument cluster. Enduro lighting. Additional chassis protection. Sharing core technologies with Suzuki’s Championship-winning open-class RM-Z450, the RMX450Z rewrites the rules for serious trail riders.

• 449cc 4-stroke, 4-valve, liquid-cooled, fuel-injected DOHC powerplant is based on the high-performance and reliable RM-Z450.

• Minimal differences as compared to the RM-Z450 motocross engine includes 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.

• A larger magneto-generator is fitted to charge the battery and power the lights. The increased mass also aids traction.

• Strong 5-speed transmission with wide gear ratios and primary/final drive ratios selected to suit various situations from steep trails to open terrain.

• 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.

• Rear suspension linkage geometry combines the RM-Z series' renowned turning-on-rails abilities with optimized handling performance for trail rides.
