EBC CSK99 Heavy Duty Clutch Spring - Kit

The EBC CSK99 Heavy Duty Clutch Spring Kit is designed to restore and improve clutch performance in motorcycles where stock springs have weakened over time. Engineered for riders who demand consistent clutch engagement and improved power transfer, this complete spring set replaces worn factory springs that lose tension after extended use and exposure to heat cycles.

Key Features:

• 10% stiffer than OEM springs for improved clutch holding power
• Complete engine set includes all springs needed for installation
• Prevents clutch slippage under hard acceleration and high-performance riding
• Manufactured to precise tolerances for consistent spring rate
• Direct replacement for worn or fatigued factory springs

These upgraded springs provide firmer clutch engagement and help maintain proper clutch pack pressure, especially important for bikes with modified engines or those used in aggressive riding conditions. Note that the clutch lever will feel slightly firmer after installation due to the increased spring tension. Test ride in a safe area to familiarize yourself with the updated clutch feel before normal operation.
