Product Description

The ProX 16.940014 Clutch Master Cylinder Rebuild Kit provides a complete overhaul solution to eliminate spongy hydraulic pull, fluid bypass, and pressure loss at the lever. Precision-engineered for modern Kawasaki motocross and off-road models, this comprehensive package restores positive lever engagement and crisp disengagement to keep your dirt bike operating at peak performance.

Manufactured to match exact OEM-level tolerances, every internal component is designed to endure aggressive heat cycles and high-pressure fluid transfer under demanding track conditions. Rebuilding your master cylinder body with fresh, precision-molded internal seals prevents air intrusion, stopping fluid degradation and returning your hydraulic system to consistent, factory-level clutch control.

Expert Pro-Tip: Thoroughly clean and inspect the inside of the master cylinder bore using rubbing alcohol and a lint-free cloth before reassembly. If you feel any deep scoring or ridges inside the aluminum cylinder wall with your fingernail, new seals will tear quickly and the entire master cylinder housing must be replaced.
