The PROX 17.CS63051 clutch spring kit is designed for KTM SXF 250, SXF 350 and HUSQVARNA FC 250, FC 350 from 2003 to 2015. 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.
Every time you change the plates, or as soon as the free length falls below the minimum.
Founded in 1975 and based near Amsterdam, ProX specialises in engine and clutch wear parts for off-road bikes. The brand has most of its range made in Japan, by OEM suppliers, for quality on a par with the original parts.
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.
