EK Chain 525Z3DMLJK Z-Series Rivet Master Link Pitch - 3D 525

The EK Chain 525Z3DMLJK is a rivet-type connecting master link designed as a direct replacement for EK's 525 Z3D (ThreeD) premium motorcycle chain series. Engineered in Japan to the same exacting standards as the Z3D chain itself, this master link ensures a secure, performance-matched connection when installing or replacing your drive chain.

Key Features:

• Rivet-type design — permanent, high-strength connection for maximum security under hard acceleration and high-load conditions
• 525 pitch — engineered exclusively for use with EK 525 Z3D series chains
• 3D outer plate profile — matches the signature curved, forged outer plate geometry of the Z3D chain for a seamless fit and consistent stiffness
• Includes o-rings and chain grease — everything needed for proper sealed installation
• Made in Japan — manufactured to EK Chain's premium quality standards
• Black finish — matches the Z3D chain's black colorway for a clean, consistent appearance

The rivet master link requires a proper chain press tool and calipers for correct installation. Always rivet the pins to the manufacturer-specified diameter to ensure the link articulates freely and matches the width of the factory-pressed links. This master link is sold individually.
