EBC CSK229 Heavy Duty Clutch Spring - Kit 10% Stiffer Than Stock

The EBC CSK229 Heavy Duty Clutch Spring Kit is an OEM-upgrade replacement designed to restore and enhance clutch performance on motorcycles experiencing spring wear or heat degradation. Each kit includes 4 heavy-duty clutch springs engineered to be 10% stiffer than stock springs.

Key Features:

• 10% stiffer than OEM springs for improved clutch engagement
• Prevents slippage from prolonged heat exposure and normal wear
• Smoother, faster clutch engagement for cleaner takeoffs
• Reduces effort required for speed shifting
• Complete kit includes 4 springs for full clutch replacement
• Direct OEM upgrade - bolt-in installation

Performance Benefits:

The increased spring tension delivers more positive clutch engagement, eliminating the mushy feel that develops as stock springs weaken over time. Riders will notice smoother power delivery during acceleration and more precise shifting under aggressive riding conditions. The stiffer springs maintain consistent clutch pack pressure even under high-temperature operation, preventing clutch slip during hard launches or extended high-RPM use.

Installation Note:

The increased spring stiffness will result in a slightly firmer clutch lever pull. While this may cause hand fatigue during extended stop-and-go traffic riding, the performance advantages make this an excellent upgrade for sport riding, racing, or any application where clutch performance is critical.
