Overview

The BikeMaster 520BMXR Rivet Chain Master Link is an O-ring chain designed for high durability. Its components are optimized with computer analysis for higher tensile strength, and a specially controlled heat treatment results in a tougher material. The reinforced roller offers increased impact resistance and longer durability.

This master link has an average tensile strength of 9,000 lbs and is suitable for engines up to 1,000cc for street use or 750cc for off-road use. It is important to correctly match this chain to your machine's size and power output to prevent potential failure. The installer is responsible for ensuring proper chain selection and installation.
