Which Gear is More Fuel-Efficient for Motorcycles

[SanJayden]

In theory, higher gears result in lower fuel consumption, and this holds true in practical performance as well. However, the prerequisite still depends on the engine RPM, as it is the fundamental condition for gear shifting. If the RPM fails to meet the shifting requirements, smooth gear shifting and normal vehicle operation cannot be achieved. From practical riding experience, maintaining the engine RPM at a moderate level tends to make the vehicle relatively more fuel-efficient. This is because, under such conditions, the engine bears the least load, operates more smoothly, and the throttle opening is not too large, resulting in relatively less fuel entering the cylinder. The theoretically most fuel-efficient state of a vehicle depends on its economical speed, while the actual performance is determined by the coordination between engine RPM and gear selection. To intuitively achieve this state, one needs to refer to the vehicle's current speed. Therefore, in the end, achieving fuel efficiency in a vehicle still revolves around maintaining the economical speed.
