BikeMaster - bkm197327 - 520x118 BMXR X-Ring Chain

Ideal OEM replacement offering 1.5 to 2x longer wear resistance than regular O-ring chains. Each refined component, designed with computer analysis, provides higher tensile strength. Specially controlled heat treatment means tougher material and more durability. Q4 seal ring and reinforced pin and roller provide superior wear resistance, higher impact resistance and endurance. Q4 seal ring offers less friction, which minimizes power loss, almost half that of standard O-ring chain.

• Max engine size of 1,000cc street/750cc offroad
• Includes rivet master link and clip master link

The BikeMaster 520x118 BMXR X-Ring Chain is an OEM replacement chain designed to provide 1.5 to 2 times longer wear resistance than regular O-ring chains. Each component is refined using computer analysis to support higher tensile strength, while controlled heat treatment produces tougher material and enhanced durability.

A Q4 seal ring, reinforced pin, and reinforced roller help deliver wear resistance, impact resistance, and endurance. The Q4 seal ring also reduces friction, helping minimize power loss to almost half that of a standard O-ring chain. This chain is suitable for engines up to 1,000cc for street applications or 750cc for off-road applications.
