About this collection
Clutch slave cylinders
Racing clutch slave cylinders from STM, K-Bike and CNC Racing — oversized billet cylinders that lighten lever pull and sharpen engagement on hydraulic clutches.
A larger slave piston changes the hydraulic ratio: less finger effort, more precise take-up, no more forearm pump in long sessions. Direct replacements for specific engines, seals included, bleed and go.
