There’s a lot going on in there...
Neil Spalding, Owner of Sigma Performance, Sigma Performance make slipper clutches for race bikes around the world, and Neil was formerly Eurosport’s Motogp tech guru.
Your clutch is a tap, transmitting power from the engine to the gearbox. With no clutch you can’t stop the flow of power, so can’t change gear or stop without stalling.
Most clutches have multiple friction plates made from a material similar to brake pads, with plain steel plates in between, all held tightly together by heavy springs. The friction plates spin with the engine, the steel plates spin with the gearbox, so when you pull the clutch lever the springs release the pressure, allowing the plates to spin independently.
There are two types of motorcycle clutch, wet and dry. Dry clutches run without oil so are lighter but are less common. Most modern bikes run wet clutches, which are lubricated
by the engine oil. This can shorten the life of the oil but makes the clutch smoother, quieter and run cooler. Some European bikes like Moto Guzzis and BMWS use a dry, single-plate clutch much like a car.
‘Heavier clutch springs are needed for faster riding or trackdays’
In a wet clutch, oil is used to make the changing of gears smoother and quieter Supersport teams replace clutch parts every weekend
