Products for Large and Small Motorcycles


CV Carburetor

The CV carburetor uses engine vacuum to raise the slide valve and maintain the throttle opening angle in proportion to the engine vacuum. From the point of view of fuel efficiency and emissions regulations, it boasts high performance and quality.

Piston Carburetor

The piston carburetor uses the throttle cable to raise the direct slide valve and adjust the throttle opening angle. The design is simple and easily maintained, contributing to cost reductions.

FI System

DBW Throttle Body

The throttle valve is opened and closed by an electric motor in response to signals from the ECU. The rider's will is transmitted by electrical wires in optimum condition via the accelerator position sensor (APS) and ECU. The engine is controlled to conform with the state of the motorcycle body.


Under electronic control, fuel particles tens of microns in size are sprayed into the engine. Compact, lightweight, quiet design. In responding to the shift to fuel injection in motorcycles, it has also achieved cost reductions.

Fuel Pump Module

Filtered fuel is pumped into the injector by the fuel feed pump (FFP). At that point, the integrated pressure regulator component maintains a constant pumping pressure.

Electronic Control Unit

This determines the volume of air supplied to the engine and the fuel injection amount on the basis of signals from various sensors. Fine control is applied on the basis of Information from the various sensors and can even provide a solution to contradictory problems such as fuel consumption and emissions levels as well as engine output.

Safety Products

Airbag G Sensor

This detects deceleration of the vehicle. The deceleration of the part where the sensor is mounted is digitally converted and transmitted to the airbag ECU using an exclusive communication technique.

Airbag ECU

This activates the airbag when the motorcycle is involved in a frontal collision. Mathematical operations are performed on signals from multiple airbag G sensors to determine the necessity of releasing the airbag when a vehicle collision is detected.
