The BikeMaster 520BMXR is an ideal OEM replacement chain for street and off-road powersports applications, offering approximately 1.5 to 2 times the wear resistance of a regular O-ring chain. Each refined component is engineered using computer-assisted analysis to help deliver higher tensile strength, consistent performance, and dependable service life. This chain is designed for engines up to 1,000cc on the street or 750cc in off-road use.
Specially controlled heat treatment produces tougher material for improved durability under demanding riding conditions. The Q4 seal ring, reinforced pins, and reinforced rollers work together to provide superior wear resistance, increased impact resistance, and long-lasting endurance. The Q4 seal ring also helps reduce friction, minimizing power loss to nearly half that of a standard O-ring chain for efficient power transfer and responsive performance.
The BikeMaster 520BMXR includes both a rivet master link and a clip master link, giving riders flexibility during installation or maintenance. Its gold finish adds a distinctive appearance while supporting the durable construction expected from BikeMaster powersports components. Designed as a practical replacement solution, this chain is well suited for riders seeking reliable drivetrain performance, reduced friction, and extended wear life.
