The system features dual throttle cables that are connected to the handlebar throttle assembly. A throttle position sensor (TPS) relays airflow data to the ECU, which in turn calculates the amount of oil and fuel delivered to the engine.
The 4-stroke range features a 42 mm Keihin throttle body. The injector is placed accordingly to ensure the most efficient flow of fuel into the combustion chamber. The throttle cable is mounted directly without a throttle linkage providing more immediate throttle response and feeling.

For the 2-stroke models the switch allows for selection between the standard ignition timing and a slightly retarded timing, to be used in low traction conditions. The map switch fitted to all 4-strokes also activates an innovative traction control feature. The system functions by analyzing throttle input from the rider and the rate at which RPM increases in the engine. If the RPM increases too quickly, the ECU will register a loss of grip thus reducing the amount of power to the rear wheel for maximum traction.
- Standard map switch → alter engine characteristics depending on conditions
- 2-strokes → option to select different ignition timings
- 4-strokes → ability to change engine characteristics & activate traction control
