EBC CSK105 Heavy Duty Clutch Spring - Kit

The EBC CSK105 Heavy Duty Clutch Spring Kit is designed to restore and enhance clutch performance on motorcycles experiencing clutch slip or reduced engagement quality. This kit replaces worn factory springs that have degraded from prolonged heat exposure and normal wear cycles.

Key Features:

• 10% stiffer spring rate compared to OEM specifications for improved clutch engagement
• Prevents clutch slip under aggressive riding conditions
• Smoother, more positive clutch engagement for better takeoff control
• Faster, more precise shifting with reduced effort during speed shifts
• Complete kit includes all necessary springs for installation
• Direct OEM replacement upgrade—no modifications required

Performance Benefits:

The increased spring tension provides more consistent clutch pack clamping force, which translates to smoother power delivery during acceleration and more reliable engagement under high-load conditions. The stiffer springs do result in slightly increased lever effort, which may be noticeable during stop-and-go traffic riding. However, most riders find the trade-off worthwhile for the improved clutch feel and performance gains during spirited riding and track use.

Ideal for riders looking to restore worn clutch performance or upgrade to a more positive-feeling clutch engagement without replacing the entire clutch assembly.
