Motorcycle clutch slippage can be caused by the following reasons: 1. Wear: The friction plate of the driven disc is excessively worn or the rivets are exposed. Replace the friction plate of the driven disc or address the exposed rivets. 2. Clutch pressure plate spring: Too soft or broken. Replace the pressure plate spring. 3. Clutch pedal: Free travel is too small. Seek professional help to adjust the free travel. 4. Driven disc friction plate: Contaminated with oil or hardened due to aging. Clean or replace the driven disc friction plate. 5. Clutch: Loose bolts connecting to the flywheel. Tighten the bolts connecting the clutch to the flywheel. 6. Clutch master cylinder: Return oil hole blocked. Clean or replace the clutch master cylinder.

I've been repairing motorcycles for years, and clutch slippage is mostly caused by worn clutch plates or a loose cable. First, you need to check the free play of the lever: twist it to see if it's too loose; if it is, try tightening it a bit by adjusting the cable nut. If it still slips after adjustment, the clutch plates might be worn out, and you'll need to open it up for inspection and replacement; don't push it, as continued wear can cause more damage. Also, for wet clutches, pay attention to the engine oil—low oil level or dirty oil can reduce grip and cause slippage. Regularly clean and maintain these parts during routine maintenance; for safety, don't ride too far if you notice an issue—get it fixed at a professional repair shop right away to avoid trouble on the road.

I often commute by motorcycle and have suffered from clutch slippage: the revs go up but the bike moves slowly. My solution is to check the handlebar tightness; if it's too loose, I try tightening the cable. If that doesn't work, I check the oil level in the wet clutch—open the dipstick, and if the oil is too low, top it up with clean oil. If the problem persists, the clutch plates are definitely worn out and it's best to replace them. Timely action is crucial; last time I delayed, I almost had an accident. The repair shop mechanic, with his extensive experience, fixed it easily for me. I recommend you also maintain these areas regularly for a more worry-free ride.

Clutch Slippage is Extremely Dangerous: The engine revs at high speed but the car doesn't move, making it very easy to lose control and crash. As soon as you notice the problem, pull over immediately; do not continue riding. Check if the cable is loose or stuck, and try adjusting it tighter. If that doesn't work, issues like worn clutch plates or oil problems require professional attention; avoid DIY repairs to prevent further damage. Safety first—get it repaired as soon as possible to ensure your safety, and don't take risks to save money.
