EBC Clutch Spring

These are coil springs, 4 to 8 pieces per set, made from heat-treated high-carbon steel and available in different shapes and sizes offering different spring tensions depending on bike size and your engine's power. It is important to note that you cannot alter the basic shape of these springs for a performance advantage, but you can purchase an EBC Brakes CSK kit whose winding material is slightly softer and offers 10 to 15% higher clamping pressure. This can help reduce clutch slip or rapid wear on your machine. All springs fatigue and should be replaced with every engine rebuild or clutch overhaul.
