What is the fuel consumption of an EFI motorcycle?
2 Answers
For an EFI motorcycle with a single-cylinder 150cc engine, the fuel consumption is approximately 4-5 liters per 100 kilometers. Fuel-saving conditions: To achieve better fuel efficiency with an EFI motorcycle, the software of the entire EFI system must be perfectly matched with the engine hardware. The quality of motorcycle hardware components such as fuel injectors and sensors must meet high standards. EFI motorcycles: An EFI motorcycle is a new type of motorcycle that uses a microcomputer to control the fuel injectors, supplying fuel only to the cylinders that need to work based on the engine load. Compared to traditional carburetor motorcycles, EFI motorcycles save fuel—achieving over 20% better fuel efficiency than their carburetor counterparts. With digital ignition and fuel injection, EFI motorcycles reduce fuel consumption and emissions, making them more environmentally friendly and compliant with Euro 11 emission standards. They also feature easy starting and stable idling.
My EFI motorcycle is 150cc, with a daily commuting fuel consumption of about 45 kilometers per liter. In the city with frequent traffic lights, it might drop to 40 kilometers, while highway cruising can reach over 50 kilometers. Maintaining proper tire pressure, regular oil changes, and clean filters can help save a bit more. Larger displacements consume more fuel; a 125cc might get around 50 kilometers, while a sporty 600cc or above might only get just over 30 kilometers. Riding habits have a big impact—sudden acceleration and braking consume more fuel, while steady-speed riding is the most economical. I think weather also plays a role; using the air conditioning and fans in summer consumes a bit more, and cold starts in winter when the engine warms up slowly also slightly increase consumption. Overall, EFI is more fuel-efficient than old carburetors, making it suitable for city commuting.
