Features
• Updated and lighter frame with streamlined shock mount and steering head areas for enhanced flex and cornering agility, and revised wall thicknesses in higher stress areas for improved overall strength
• New engine mounts with cut-outs to improve chassis flex characteristics and stability also reduce weight
• Updated rear shock linkage with lower-friction seals and a lighter-weight linkage bolt
• Revised fork and shock settings to improve weight distribution and increase overall response
• New chain slider and guide for improved durability
• Stiffer, one-piece airbox design with optimized air intake for better air flow and filter protection
• Stronger rear brake pedal for improved durability and braking performance
• Updated rubber cushion beneath fuel tank for protection
• One-piece fuel pump and integrated filter allows the tank to be emptied further
• Updated bodywork and ergonomics offer riders improved ease of movement and enhanced comfort for less fatigue
• Higher, wider seat and revised tank shrouds offer more grip under hard acceleration
• New graphics that are applied using in-mold technology for a long-lasting finish
• Durable, fine-punched cam chain runs on low-friction chain guides for optimal efficiency and reliability with single oil spray jet ensuring effective cooling
• Rollover Sensor (ROS) for EMS cuts ignition and shuts off engine in the event of a severe crash
• Hour meter with integrated fuel level indicator and status LED
• Combined thumb-operated start/stop switch
• Traction Control analyzes throttle input from rider and engine RPMs; EMS reduces power to rear wheel when loss of grip is sensed
• Quickshift function, with sensor on shift drum, is activated by QS button on map switch and allows upshifting (from second gear upwards) without use of clutch while throttle is fully open
• Launch Control: engaged by pressing Traction Control and Quickshift buttons simultaneously; deactivates automatically after gear change
• Two engine maps, selectable via handlebar-mounted switch:
— Map 1 (white): standard for linear predictable power, suited to hard pack and slippery tracks
— Map 2 (green): aggressive for improved throttle response and sharper explosive power output, suited to sand and heavier track conditions
Miscellaneous
• Airbox: tool-free access to Twin Air filter via left side panel
• Cooling: liquid
• Engine: single-cylinder, 4-stroke, SOHC, rocker arm actuated valves, aluminum cylinder and forged bridged-box CP piston, bearing-bridge design camshaft, high-pressure die-cast crankcase
• Exhaust: flow-designed resonance chamber integrated into two-piece header pipe, short/compact aluminum silencer
• Frame: central double-cradle-type 25CrMo4 steel, metallic blue powder coating; two-piece aluminum-reinforced polyamide subframe (60% polyamide, 40% aluminum) with cast aluminum subframe spars and frame mounts; hollow die-cast aluminum swingarm with 22 mm rear axle
• Grips: ODI, lock-on
• Handlebar: ProTaper, aluminum, 22/28 mm diameter
• Handlebar mount: two mounting options — rubber damped for less vibration or fixed for enhanced feedback
• Hubs: CNC-machined
• Radiators: high-strength aluminum, with internal thermostat
• Rims: D.I.D, anodized aluminum
• Triple clamps: CNC-machined with stiffer upper clamp
• Includes air pump for fork
