Most geared motorcycles use a **wet multi-plate** clutch: [friction plates](https://motorsikletparcasi.com/en/glossary/clutch-plates) alternate with steel plates and are clamped by springs. Because the clutch runs in engine oil, the oil choice matters (see [JASO MA](https://motorsikletparcasi.com/en/glossary/jaso-oil-standard)).

It is operated by a [clutch cable](https://motorsikletparcasi.com/en/glossary/clutch-cable) or a hydraulic master cylinder.

## Symptoms of a problem

- **Slipping:** revs rise when you open the throttle but speed does not follow
- **Dragging:** harsh gear changes, the bike pulls forward with the lever in
- A heavy lever or a changing bite point
