Basically the pressure plate is connected to clutch centre hub ( wheel driven side). The engine is connected to the clutch drum (engine driving side). The only thing that connects the two are the clutch friction plates (clutch basket) and plain plates (clutch centre) under clamping pressure from the six clutch springs.
When the clutch is dis-engaged (lever pulled in) the spring pressure is overcome via hydraulic pressure, releasing the clamping force, allowing the centre hub and the clutch drum to rotate independantly of one another. The drum will continue to turn as it is driven by engine rotation but the centre hub (mated to the pressure plate) will due to internal friction eventually stop rotating when the bike is stationary.
Any help
