This fuel injection system provides only the required amount of petrol mixtrue according to the riding condition. So this will help to increased mileage and cleaner emissions from the motorbike.

Depending on the details, the control unit will signal to inject proper amount of fuel mixture to the motorcycle engine.

Some motorcycles are available for the buyer to choose either Carburetor or Fuel Injection fitted model to buy. The fuel injection model is priced around IRs 5,000/- more than the carburetor fitted model.
