EBC CSK1 Heavy Duty Clutch Spring - Kit

The EBC CSK1 Heavy Duty Clutch Spring Kit is designed to replace worn or heat-damaged OEM clutch springs with upgraded components that enhance clutch performance and longevity. These springs are engineered to be approximately 10 percent stiffer than stock springs, providing improved clutch engagement characteristics for demanding riding conditions.

Key Features:

• 10% stiffer spring rate compared to OEM specifications for enhanced clutch engagement
• Prevents clutch slippage caused by heat exposure and spring fatigue
• Smoother clutch engagement and faster takeoff response
• Facilitates quicker, more positive gear changes during aggressive riding
• Complete kit includes all necessary springs for full clutch replacement
• Direct OEM replacement—installs using stock hardware and procedures

The increased spring tension results in a slightly firmer clutch lever feel, which may be noticeable during extended riding in stop-and-go traffic. However, this trade-off delivers significantly improved clutch performance, including crisper engagement, reduced slip under load, and more consistent feel throughout the friction zone. Ideal for riders seeking enhanced clutch performance for sport riding, track use, or replacing worn springs on high-mileage motorcycles.
