  • 42 mm Mikuni throttle body fuel injection system with TPS & ISC.
    • 12 hole injector for optimum fuel atomization for maximum power output
    • TPS (throttle position sensor) is used to more precisely calculate the fuel injection quantity for optimum power & excellent throttle response at all rpms
    • ISC (Idle speed control) helps ensure a steady idle even during warm up
    • light action throttle lever means less fatigue during long motos.
    • other fuel injection benefits include; excellent throttle response, choke-free starting, good fuel economy & reduced emissions
  • “No tools required” air box with washable dual stage foam air filter.
    • washable foam filter features tool-free access for fast servicing
    • dual stage design provides maximum filtering
    • no tools required air box drain
  • Compact 5-speed manual transmission with reverse.
    • optimized gear ratios match engine output for maximum performance
  • Compact, slipper clutch with assist.
    • reduces effects of engine braking allowing the rider to control corner entry speed more precisely by using only the brakes… reducing lap times
    • provides optimum control (less rear wheel chatter) & improved suspension performance
    • assist function reduces clutch lever effort by up to 20%, improving rider stamina
    • quick access outer clutch cover for fast clutch servicing
  • O ring chain final drive.
    • easy to adjust
    • heavy duty O-ring chain offers excellent strength & durability
  • High capacity cooling system with electric cooling fan.
  • Maintenance-free transistor controlled ignition (TCI).
    • produces a strong spark for fast starts
    • provides precise ignition timing / mapping for optimum performance at all rpms
  • Performance tuned exhaust system with cleanable spark arrestor.
    • tuned system for maximum power
    • spark arrestor prevents stray sparks from exiting the exhaust
  • Air Injection System (AIS) injects fresh air into exhaust ports to fully burn any unburnt fuel, reducing exhaust emissions.

CHASSIS

  • Lightweight, combination cast aluminum & steel frame with “tuned” rigidity balance.
    • unit width is 1,240 mm or 48.8″ wide, combining with a low seat height of 810 mm (31.9″) for flat, stable handling
    • aluminum frame is bolted together, instead of welded for maximum durability
    • compact design provides nimble, responsive handling
    • engine is mounted low in the frame to reduce the centre of gravity & centralize mass for exceptional handling
    • rigidity balance maximizes handling & suspension performance. Frame is optimized to provide a balance of strength, rigidity & tuned flex.
  • Detachable aluminum rear subframe.
    • reduces weight
    • allows easier rear shock access
    • reduces costs in the event of damage
