EBC CSK259 Heavy Duty Clutch Spring - Kit 6 Springs Per Set

The EBC CSK259 Clutch Spring Kit provides a performance upgrade for motorcycle clutch systems with six precision-engineered springs designed to restore and enhance clutch performance. These springs are engineered to be approximately 10% stiffer than OEM specifications, preventing damage from prolonged heat exposure and normal wear while delivering improved clutch engagement characteristics.

Key Features:

• 10% stiffer spring rate than stock for improved clutch engagement
• Six-spring kit provides complete clutch spring replacement
• Prevents clutch slippage from worn or heat-damaged springs
• Smoother, faster clutch engagement for improved power transfer
• Enables quicker, more precise shifting under performance riding conditions
• Direct OEM replacement design for easy installation

The increased spring tension results in a slightly firmer clutch lever pull, which may increase hand fatigue during stop-and-go traffic or extended riding. However, this trade-off delivers noticeably smoother takeoffs and significantly faster shift response, making the CSK259 an ideal upgrade for performance-oriented riders who prioritize clutch response and reliability over maximum lever comfort.
