A dry clutch is that part of the engine which engages or disengages power from the engine crankshaft to transmission. A dry clutch is the mechanism with the help of which you change gears. In other words, dry clutch turns on or off power to the rear wheel. Using air to cool the clutch is called a dry clutch. Because dry clutches do not have the resistance of engine oil, they generally respond faster and have a larger bite force. Dry clutches generally use exposed methods to dissipate heat.
