BikeMaster 520x120 BMXR X-Ring Chain - Orange

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.

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

The BikeMaster BMXR 520 X-Ring Chain is engineered as an OEM-quality replacement for powersports applications requiring dependable strength, reduced friction, and extended service life. Designed using computer-aided analysis, each chain component delivers increased tensile strength for reliable performance under demanding riding conditions. Compared with conventional O-ring chains, the BMXR design provides approximately 1.5 to 2 times longer wear resistance when properly maintained.
Specially controlled heat treatment produces tougher, more durable chain components, while the reinforced pins and rollers improve impact resistance and endurance. The Q4 seal ring helps retain lubricant and reduce friction, minimizing power loss compared with standard O-ring chain designs. This combination of refined construction and efficient sealing makes the BikeMaster BKM197456 chain a practical choice for street motorcycles, off-road machines, and other compatible powersports applications.
This orange 520 chain includes both a rivet master link and a clip master link for installation flexibility. It is intended for engines up to 1,000cc in street applications or up to 750cc for off-road use. Verify the required chain size, link count, master-link style, and vehicle fitment before installation. For best results, follow the motorcycle manufacturer’s installation and maintenance recommendations, including correct alignment, adjustment, and regular lubrication.
