The topic of motorcycle fuel saving often comes up, and veteran drivers will have their own tips.

But someone also said, "have already ridden a motorcycle, also consider what fuel consumption?" From God's point of view, this sentence is fine, but don't stand up and say it. Ordinary people live on a budget and save what they can, so the topic of motorcycle fuel saving is still worth discussing.

1. What is the fuel saving state of the motorcycle?

For small displacement motorcycle, its own fuel consumption is not too high, taking 125 models for example, the comprehensive fuel consumption of 100 kilometers is about 2 liters.

But if you want to reach this level, there must be preconditions, if the vehicle performance is assumed to be consistent, it and our driving conditions and engine speed has to be related.

So here comes the core problem. The fuel consumption of a motorcycle is determined by the speed of the engine. This should not be difficult to understand, no one would think that a high gas gate is more fuel efficient than idling? If so, it's time to rethink.

Thus we can conclude that the lower the engine speed, the smaller the fuel consumption will be, and vice versa.

However, the level of fuel consumption in normal riding is also directly related to the actual speed of the vehicle. It does not mean that the low speed will save fuel, if so, everyone can ride in one gear on the line.


So there is an economic speed, it is not a vague concept, or manufacturers publicity gimmick, but a real existence.

The so-called economic speed is simply that the motorcycle riding at the current speed is the most fuel-efficient state, and for most small-displacement models, the speed is generally between 50km/h~60km/h.

Therefore, as long as the conditions permit, the current speed can be achieved to achieve the lowest fuel consumption, but in reality, this speed is often difficult to achieve, especially in urban areas.

2. How to maintain economic speed

Figure out the relationship between small-displacement motorcycle engine speed and vehicle speed and fuel consumption, then the next problem is how to maintain the relationship between them, let it reach the best state.

For the scooter, because it does not involve manual intervention shift operation, so the most effective way here is to control the throttle, and avoid sudden braking, so that it does not have a large fluctuation of speed performance, can be as uniform as possible to ride, if the actual ride in the process of the throttle opening up and down, speed up and down then the purpose of fuel saving almost can not be achieved.

As for the gear, it is to shift the gear reasonably and use the gear to amplify the characteristics of power transmission to make up for the influence of the speed level on the fuel consumption of the vehicle in the actual riding. Generally speaking, when the speed is maintained at three or four thousand rotas, an ideal gear should be selected according to the actual performance of the vehicle, so that it can run as close to the economic speed as possible, so as to achieve the purpose of fuel saving. But it's a personal quest.

Taking the Jialing SVR180 I am riding as an example, when its speed is at three or four thousand RPM on flat road, it can reach the economic speed in fifth and sixth gear, and the speed of the sixth gear engine can drop. If it keeps riding in this state for a long time, its fuel consumption of 100 km is quite considerable, basically around 1.6L.

Therefore, the control of speed, reasonable shift, as far as possible to maintain a uniform speed riding is the most fuel efficient state of the motorcycle, and this process should also reduce the weight, avoid sudden braking. But it's tiring, and there's not a lot of passion.

In a word, for small displacement motorcycles, 50km/ H-60km /h economic speed is the most fuel-efficient state, but although this will reduce fuel consumption, but also lose some fun, depending on how to choose.
