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 and 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 35 W headlight is smoothly incorporated into the front number plate.
• Trim, low-draw LED tail light 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. Instruments include a low fuel level warning light.
• Champion Yellow bodywork (including yellow fenders and white front number plate) comes with race team-inspired graphics package.
• Gripper seat, with projected cross-shaped patterns on its blue top surface, aids rider control.
