The BikeMaster 520 BMXR O-Ring Motorcycle Chain is an ideal OEM replacement for powersports applications requiring dependable performance and extended service life. Designed to deliver approximately 1.5 to 2 times the wear resistance of a standard O-ring chain, this chain uses refined components developed through computer-aided analysis to provide increased tensile strength and reliable durability. Its construction is suited for motorcycles with engines up to 1,000cc for street use or 750cc for off-road applications.
Specially controlled heat treatment produces tougher chain components for improved durability under demanding riding conditions. The reinforced pins and rollers help increase wear resistance, impact resistance, and overall endurance, while the BikeMaster Q4 seal ring helps retain lubrication and protect internal components from contamination. The low-friction seal design also helps reduce power loss, delivering nearly half the friction of a standard O-ring chain for efficient power transfer.
The BikeMaster 520 BMXR includes both a rivet master link and a clip master link, providing installation flexibility for a range of service and repair needs. The nickel finish adds a clean, durable appearance while supporting long-term performance. When replacing a worn or damaged chain, verify chain size, master-link style, and motorcycle application requirements before installation. Part number BKM197464 identifies this BikeMaster replacement chain component.
