EBC CSK4 Heavy Duty Clutch Spring - Kit

The EBC CSK4 clutch spring kit provides a performance upgrade for motorcycles experiencing clutch slip or fade due to worn or heat-damaged springs. These heavy-duty springs are engineered to be 10% stiffer than OEM specifications, delivering improved clutch engagement and more positive shifting performance.

Key Features:

• 10% stiffer than stock springs for reduced clutch slip
• Prevents damage from prolonged heat exposure and normal wear
• Smoother, faster clutch engagement for improved takeoff
• Enables quicker, more precise speed shifting
• Direct OEM replacement upgrade
• Complete kit with all necessary springs

Performance Notes:

The increased spring tension provides better clutch performance and longevity, though riders should note that lever pull will be slightly firmer than stock. This may cause hand fatigue during extended stop-and-go riding or heavy traffic conditions. The trade-off is significantly improved clutch response, reduced slippage, and more consistent performance under demanding riding conditions.

Ideal for riders seeking to restore or enhance clutch performance on sport bikes, street motorcycles, and performance applications where positive clutch engagement is critical.
