Single cylinder motorcycles, such as the Zongshen RX3, employ a system using the MT05 engine control module (ECM).

This ECM receives information from a number of sensors.

Zongshen provides the crank sensor, which is located inside the Zongshen NC250 engine.

The engine temperature sensor measures coolant temperature, and is located in the thrermostat housing under the fuel tank.

The oxygen sensor is attached to a bung on the exhaust header.

The manifold absolute pressure (MAP) sensor, manifold air temperature (MAT) sensor, and fuel injector are attached to the intake manifold.

The throttle position sensor is incorporated in the Delphi throttle body.
