In the automotive field, generally in order to design a battery life of at least 500 kilometers, the size of the fuel tank will be flexibly changed. For example, Japanese cars are more fuel-efficient, and sometimes a tank of fuel can even last for more than 800 kilometers. But for motorcycles, the battery life can exceed 500 kilometers before the lights are turned on, which is very rare, and the battery life of many motorcycles is indeed less than 500 kilometers.

Why is the design of motorcycle endurance so short?

The first point: the size of the motorcycle body affects the size of the fuel tank

From civilian-grade motorcycles to fun-type motorcycles, the general fuel tank size rarely exceeds 20 liters, unless the motorcycle with a particularly large displacement can reach 20 liters.

Some upgraded motorcycles will light up to remind you to refuel when the battery life reaches 200 kilometers. In China, the 125 and 150 motorcycles with small displacements perform well, but they are not suitable for long-distance commuting.

The fuel tank of a motorcycle is not particularly large because it is limited by the size of the body. If the fuel tank is full and prominent, the overall body may not be very coordinated, and the appearance and appearance will be more abrupt.

The second point: the size of the fuel tank will affect the riding control

The size of the fuel tank does affect the riding control. Previously, internal professional reviewers found that the car is in a full fuel state and a low fuel state, and there is indeed a difference in riding feeling.

With a large 20-liter fuel tank, when the fuel is full and when the fuel is low, the curb weight may be about 15 kg. This part of the weight is concentrated in the front of the vehicle, which will indeed affect the tracking performance of the curve.

For example, the riding experience is completely different with manned and unmanned, loaded and unloaded.

 

 

Generally, the battery life of the riding motorcycle is about 400 kilometers, and the lights are on at 350 kilometers; the battery life of scooters is shorter, and the fuel tanks of 125-level scooters are generally small. This is to increase storage space. Caused by.

If you use a motorcycle for a long-distance motorcycle tour, it would be better to refuel once a day. Although you can go to a gas station to refuel, you can also use it as a passive parking and rest, but in many areas in China, it is not very friendly to refuel motorcycles. The region even refuses to refuel motorcycles, or refueling needs to be treated differently.

The biggest benefit of motorcycles with large fuel tanks and long battery life occurs when riding on highways and traveling to remote western regions. On highways, many gas stations do refuse to refuel motorcycles, and this is also true in remote western areas.

Can the fuel tank be made larger for motorcycles?

There is no absolute difficulty in the realization of the technology, but it will increase the technical cost. For example, the fuel tank volume of the Dakar Rally cross-country motorcycle even reaches more than 40 liters, and even the bottom of the rear seat is equipped with a fuel tank. If a civilian vehicle is also designed in this way, it will increase a lot of technical costs, and it is completely unnecessary.

For the needs of a large fuel tank, different riders have different rigid requirements, but for the short cruising range caused by a small fuel tank, most motorcycles will feel more uncomfortable.
