CSK Series Spring Kit by EBC — a robust clutch spring set designed for riders who are refurbishing their transmission. Made from steel, these springs replace worn components to restore a crisp clutch response and uniform pressure between the discs. Ideal for roadsters and vintage machines where throttle consistency and longevity make a difference.
This kit is suitable for both coil spring architectures and diaphragm systems. The manufacturer recommends replacing the springs when changing the clutch discs to ensure optimal performance. EBC's CSK series springs feature a 10% higher stiffness compared to original parts, providing slightly enhanced preload without major mechanical modifications.
Common applications: particularly suitable for classic roadsters such as the HONDA CB 750 K Four (1978), CB 400 F Four (1978), and CJ 360 T (1978). Replace worn springs to restore precise clutch engagement, improved throttle feel, and increased disc lifespan.
