CSK Series Spring Kit (manufacturer ref. CSK211) — EBC
Replace worn clutch springs with this EBC kit designed for sports motorcycles. Made from steel in the form of coil springs, these components complement a clutch disc change to restore correct play and preload. EBC indicates a stiffness increase of approximately 10% compared to the original springs, providing a sharper clutch response and a more precise lever feel — ideal for sporty riding where torque precision and friction point progression matter.
Workshop tip: it is recommended to replace the springs at the same time as the clutch discs to ensure even wear and optimal operation of the clutch pack.
Top application examples: YAMAHA YZF-R1 1000 (RN22 2014), YZF-R1 GP WGP 50th Anniversary (RN22 2012), YZF-R1 1000 (RN19 2008). Always check compatibility with your model and year before installation.
