BikeMaster 525x150 BMXR O-Ring Chain - Blue

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 1,100cc street/900cc offroad
• Includes rivet master link

The BikeMaster 525x150 BMXR O-Ring Chain is an ideal OEM replacement for street and off-road motorcycles requiring dependable power transfer and extended service life. Designed using computer-aided analysis, each refined component delivers increased tensile strength compared with conventional O-ring chains. This blue motorcycle chain is engineered for riders who need consistent performance, durability, and reduced maintenance in demanding powersports applications.
Specially controlled heat treatment strengthens the chain material for improved durability, while reinforced pins and rollers enhance impact resistance and endurance. The Q4 seal ring helps retain lubrication and reduces friction, minimizing power loss to nearly half that of a standard O-ring chain. This combination of features supports smoother operation and improved wear resistance, with an expected service life of approximately 1.5 to 2 times longer than a regular O-ring chain under comparable conditions.
The BikeMaster BMXR chain is suitable for motorcycles up to 1,100cc for street use or 900cc for off-road applications. It includes a rivet-style master link for secure installation. Verify chain size, link count, and motorcycle fitment before installation to ensure proper compatibility. Part number BKM197477 identifies this BikeMaster replacement chain.
