It’s common that the motorcycle clutch is stationed in the same oil as the transmission. Clutches often have stacks of alternating plain steel and friction plates and even lugs. Some plates have lugs on the interior that serves as a locking mechanism to the engine crankshaft. Any additional plates have lugs on the outer rims which allows them to lock in turn will turn the transmission input shaft. Coil springs or diaphragm spring plates are what forces the plates together and the clutch is engaged by the rider.
The most important working components of a motorcycle clutch are the friction plates. The friction plates take the abusive wear and tear of daily riding. Designed as 'disposable' items, clutch friction plates wear out and need replacement periodically. In order to prolong the useful life of your clutch, make sure that all components are properly installed and adjusted, maintain proper lubrication of your wet clutch, change your clutch oil at regular intervals using only a good quality oil with the proper viscosity. Also, it always helps to adjust your riding style to eliminate excessive slipping, which causes excessive heat. That excessive heat shortens the lifespan of your clutch friction plates. When clutch components are replaced, always use only the best parts available and replace any and all components that show signs of wear.
The most important function of the oil in a wet clutch is to serve as a coolant. The oil bathes the clutch plates and friction plates, cooling them down, resulting in a smoother clutch action and prolonging the life of the clutch. Use only motorcycle specific oils. Do not use automotive type oils in a wet clutch because they have friction modifiers, which depending on the specific oil and friction modifiers, can cause clutch plates to slip and run hotter allowing for glazing and heat related problems.
