BikeMaster 520x120 BMXR O-Ring Chain - Pink

This BikeMaster 520 BMXR Series chain uses a Q4 seal ring, which offers less friction than standard O-ring chains. This design minimizes power loss, resulting in almost half the power loss compared to a standard O-ring chain. Each component has been refined using computer analysis to provide higher tensile strength, and a specially controlled heat treatment process makes the material tougher and more durable. This chain is designed as an ideal OEM replacement, offering 1.5 to 2 times longer wear resistance than regular O-ring chains.

The reinforced pin and roller, along with the Q4 seal ring, contribute to superior wear resistance, higher impact resistance, and increased endurance. This chain is suitable for engine sizes up to 1,000cc for street use or 750cc for off-road applications. It features an average tensile strength of 9,000 lbs. The chain includes both a rivet master link and a clip master link for installation flexibility.
