Engine Features
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

Advanced fuel-injection system makes for extra-smooth power delivery, high fuel efficiency, and superb reliability

The airbox features a hinged lid for quick air-filter maintenance and better protection from debris

The coolant reservoir tank has a specially located filler cap for easy access


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


Chassis Features
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

Race-inspired waved disc rotors are mounted to black EXCEL aluminum rims with stainless steel spokes

High-impact, black plastic fork leg, plus rear brake rotor and caliper protectors shield these components from trail obstacles

The standard Renthal Fatbar is stronger and reduces vibration better than conventional aluminum handlebars

Bright 35W headlight is smoothly incorporated into the front number plate

Trim, low-draw LED taillight is neatly tucked under the lip of the rear fender

The full-function, dual (sport/standard) mode instrument cluster is in a durable, ultra-compact housing.

Sport mode simply shows timer, tripmeter, average speed and tire-diameter correction (to reduce information during spirited riding or competition).

Standard mode also shows speed, time, two trip lengths and voltage.

The instrument’s integrated tire diameter calculator allows precise fine tuning for different tires to ensure accuracy of the speed and distance displays.

Champion Yellow bodywork (including a yellow rear fender) with race team-inspired graphics package

Gripper seat, with projected cross-shaped patterns on its blue top surface, aids rider control
