BikeMaster 520x120 BMXR X-Ring Chain

This BikeMaster 520 BMXR X-Ring chain comes with both a rivet master link and a clip master link, giving you options for installation. It's designed as an ideal OEM replacement for motorcycles up to 1,000cc for street use or 750cc for off-road applications.

Compared to standard O-ring chains, this X-ring chain offers significantly longer wear resistance, about 1.5 to 2 times more. This improved durability comes from refined components that have been analyzed using computers to achieve higher tensile strength. The chain also undergoes a specially controlled heat treatment process, making the material tougher and more resistant to impacts and general wear. The Q4 seal ring design is a key feature, providing less friction than standard O-ring chains, which helps minimize power loss and contributes to its endurance.
