ALL BALLS Clutch Master Cylinder Repair Kit (Ref. 18-4000)
Designed for the refurbishment of clutch circuits, this ALL BALLS kit gathers the necessary parts and seals to recondition a worn master cylinder. Ideal for regular maintenance or restoration before the season, it aims to restore the sealing and reliable operation of the hydraulic system without the need for a complete part replacement.
This kit is aimed at DIY motorcyclists as well as workshops looking to eliminate leaks and play in the lever without heavy interventions. Check compatibility with your machine's original master cylinder before ordering — it is commonly used on 450 cross bikes (e.g., KAWASAKI KX 450 2026, KTM 450 SX‑F 2025, HUSQVARNA FX 450 2022) when dimensions match. Maintain control, safety, and peace of mind for your off-road or on-road rides.
