What is the function of a motorcycle clutch?

[DelBrandon]

The function of a motorcycle clutch is to transmit or cut off the power transfer between the engine crankshaft and the gearbox, enabling gear shifting and matching gearbox speeds at different times. Methods to determine clutch wear include: 1. When the engine speed remains unchanged, there is a noticeable decrease in driving speed compared to before; 2. While driving, although the engine speed increases, the change in vehicle speed is not obvious; 3. Lift the main stand to raise the rear wheel off the ground, engage first gear, maintain a small throttle, and slowly press the rear brake pedal. If the rear wheel starts to brake noticeably but the engine speed does not decrease significantly; 4. When changing the engine oil, if there are small amounts of gray material in the black oil, it can be judged as clutch wear.
