Vortex 520SRO6-MLJ EK 520 SRO6 O-Ring Chain Rivet Master Link

The Vortex / EK 520SRO6-MLJ is a rivet-type connecting link (master link) designed specifically for use with the EK 520 SRO6 O-ring motorcycle drive chain series. This replacement master link provides a secure, permanent connection that is the preferred choice for street and performance applications where maximum reliability is required.

Key Features:

• Rivet-type (MLJ) design — the most dependable master link connection method, preferred for street and high-performance use
• Compatible with 520-pitch O-ring chains in the EK SRO6 series
• 8,500 lb. tensile strength — matched to the full SRO6 chain rating
• Suitable for both street and off-road applications up to 750cc displacement
• Manufactured to EK's high-tolerance standards using heat-treated steel alloys
• Includes outer plate and rivet pins for a complete, permanent installation

Installation Note: The MLJ rivet-type master link requires a chain riveting tool for proper installation. It is not a clip-style link and should not be installed without the appropriate tooling. For applications where a rivet tool is unavailable, the SLJ screw-type connecting link is sold separately.

This connecting link is sold individually and is intended as a replacement or spare when assembling or servicing an EK 520 SRO6 O-ring drive chain. Also cross-referenced as 520SRO6-MLJ/G (gold finish variant).
