Xingfu 125 motorcycle features a circulating five-speed design, with the gear sequence being neutral, 1, 2, 3, 4, 5, neutral, and so on in a cycle. Introduction to the Xingfu 125 motorcycle: The Xingfu 125 motorcycle boasts excellent performance, with advantages such as a low failure rate in its overhead valve engine, quick acceleration, and simple maintenance. It is also highly economical, with a fuel consumption of approximately 1.8 liters per 100 kilometers, making it a very practical vehicle. Function of motorcycle gears: Shifting gears on a motorcycle is similar to that in a car. Lower gears are characterized by slower speeds but higher torque, while higher gears offer faster speeds but lower torque. This is akin to a clutch-equipped reducer. Since the engine continues to rotate once ignited, and at a relatively high speed, without gear shifting, the direct output of the engine's rotation to the wheels would not only result in excessive speed but also cause the engine to stall due to the high inertia during startup. Therefore, the transmission and gears are quite important.

I've been riding this bike for many years. The Xingfu 125 comes standard with four forward gears and one neutral gear, featuring a simple and practical design. Fewer gears actually mean fewer problems, making it most convenient for stop-and-go city traffic. First gear provides a steady start, and fourth gear is sufficient for high-speed cruising. Remember to release the clutch smoothly when shifting gears—don't force it, or you might experience slipping or damage the bike. For daily riding, don't worry too much about the multi-gear configurations of high-end bikes. This gear setup is just right, easy to maintain, and all it needs is some good engine oil.

From a mechanical structure perspective, the gear system emphasizes synchronization and durability. The Xingfu 125 typically features only four forward gears, with straightforward manual operation. First gear is for low-speed starts, second and third gears are suitable for urban commuting, while fourth gear provides stable high-speed cruising. This simple design makes the motorcycle less prone to malfunctions, allowing beginners to ride smoothly once they master it. As a side note, avoid forcing higher gears on steep slopes to prevent clutch wear and extend its lifespan. Regular oil changes help maintain gear lubrication.

From a riding safety perspective, using the correct gear ensures peace of mind. The Happiness 125 has four gears. When turning, it is recommended to downshift to second gear to control speed and avoid high-speed cornering. Starting in first gear is stable; avoid forcefully revving the engine from a higher gear, as this can overload and overheat the engine. Simple gear selection makes operation easier, reducing confusion. Develop the habit of checking before riding, and stop for repairs immediately if gear jamming occurs.
