BikeMaster 520BMXR Rivet Chain Master Link

This BikeMaster 520BMXR series master link uses a Q4 seal ring, which offers less friction compared to standard O-ring chains. This design helps minimize power loss and contributes to better wear resistance. The components are refined using computer analysis to achieve higher tensile strength, and a controlled heat treatment process makes the material tougher and more durable.

Designed for engines up to 1,000cc for street use or 750cc for off-road, this master link boasts an average tensile strength of 9,000 lbs. The reinforced pin and roller, along with the Q4 seal ring, provide improved wear resistance and higher impact resistance, making it a solid option for replacing your existing chain link.
