PROX Clutch Spring Kit for KAWASAKI KX 60, KX 65, KX 80 and SUZUKI RM 60, RM 65 1981-2025

The PROX 17.CS40012 clutch spring kit is designed for KAWASAKI KX 60, KX 65, KX 80 and SUZUKI RM 60, RM 65 from 1981 to 2025. The clutch springs clamp the plate pack together. With heat and hours of use, they lose length and strength: the clutch slips, even with plates in good condition.

Will the lever be heavier?
Springs to OEM spec restore the original lever effort. Heavy-duty springs, on the other hand, make the lever slightly stiffer.
