Clutch friction discs — a set for 125-150 cc CG engines. They work in pairs with steel discs in an oil bath and transmit torque from the engine to the gearbox.
- Signs of wear: the clutch slips, the revs rise but the speed does not, the motorcycle pulls away with a jerk.
- Soak the new discs in engine oil before installing them.
Also check the clutch springs and the steel discs for warping.
