• New fork shim stack settings improve overall balance, cornering agility, and riding comfort
• Updated shock shim stack settings to improve balance and handling
• Durable, fine-punched cam chain runs on low-friction chain guides for optimal efficiency and reliability with single oil spray jet ensuring effective cooling
• Forged brackets on lower frame rails allow for easy installation of skid plate
• 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
• Airbox: tool-free access to Twin Air filter from left side panel; includes second cover for sharper throttle response
• Engine type: single-cylinder, 4-stroke, SOHC, rocker arms, aluminum cylinder and forged bridged-box-type CP piston with anodized annular grooves, high-pressure die-cast crankcase
• Exhaust: single, flow-designed resonance chamber integrated into header pipe
• Frame: central double-cradle-type 25CrMo4 steel, two-piece polyamide/aluminum subframe with cast aluminum lower spars and frame mounts, hollow die-cast aluminum swingarm with 22 mm rear axle
• Grips: ODI, lock-on
• Handlebar: ProTaper
• Handlebar mount: two mounting options — rubber damped for less vibration or fixed for enhanced feedback; CNC-machined triple clamps
• Radiator: high-strength aluminum, with internal thermostat
• Wheels: Excel Takasago alloy, CNC machined hubs
• Includes air pump for fork
