CSK Series Spring Kit (manufacturer ref: CSK239) — EBC
Replace the clutch springs when changing the discs to maintain optimal clutch adjustment and grip. This EBC CSK Series spring kit features a bronze finish and all-steel construction, designed with coil springs for durable mechanical grip. EBC springs are 10% stiffer than the original ones.

Ideal for commonly cited machines with this kit (e.g. KTM RC 390 ABS, KTM DUKE 390 ABS, KTM RC 250 ABS), it fits into maintenance records to achieve appropriate pressure between the discs and the bell. Easy to install by a mechanic or in a workshop, this kit offers a robust and understated replacement part, designed to last and withstand the regular demands of road riding or more intensive use.
