EK Chain 525Z3DMLJC 525 Z3D Series Rivet Master Link

The EK Chain 525Z3DMLJC is a rivet-style master link (connecting link) designed specifically for use with EK's 525 Z3D series motorcycle chains. This rivet master link provides a permanent, high-strength connection that matches the rated tensile strength of the Z3D chain, making it the preferred choice for high-performance street and sport bike applications.

Key Features:

• Chain Pitch: 525 (5/8" pitch)
• Rivet-style construction for a permanent, press-fit connection — stronger and more secure than clip-type master links
• 3D (Z3D) series compatible — engineered to match EK's Z3D chain specifications and tensile strength ratings
• High-strength alloy side plates with precision-fit pins for reliable power transfer
• Sealed design to retain lubrication and resist contamination consistent with Z3D chain performance
• Includes outer plate and pre-staked/rivet pins for complete installation

Installation of a rivet master link requires a chain breaker/riveting tool to properly stake the pins. This connecting link is the OEM-recommended closure method for EK Z3D chains used in demanding riding conditions, including sport riding and track use. Always verify chain pitch and series compatibility before installation.
