The BikeMaster 525x108 BMOR O-Ring Chain is designed for dependable performance in powersports applications requiring durability and consistent power transmission. Its O-ring construction helps retain lubrication between internal components while limiting contamination, supporting longer service life in demanding riding conditions. Computer-optimized component designs provide increased tensile strength, and specially controlled heat treatment produces tougher chain material for improved durability.
The reinforced roller is engineered to withstand higher impact loads, helping the chain perform reliably under acceleration and changing riding conditions. This BikeMaster chain includes a rivet-style master link for secure installation when properly fitted with the correct tools and procedures. Always inspect the chain, sprockets, and master link during installation and routine maintenance, and follow the motorcycle manufacturer’s specifications for chain fitment, adjustment, and service.
