BikeMaster 525x108 BMXR X-Ring Chain

Ideal OEM replacement offering 1.5 to 2x longer wear resistance than regular O-ring chains. Each refined component, designed with computer analysis, provides higher tensile strength. Specially controlled heat treatment means tougher material and more durability. Q4 seal ring and reinforced pin and roller provide superior wear resistance, higher impact resistance and endurance. Q4 seal ring offers less friction, which minimizes power loss, almost half that of standard O-ring chain.

• Max engine size of 1,100cc street/900cc offroad
• Includes rivet master link

The BikeMaster 525x108 BMXR X-Ring 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 conventional O-ring chain, this chain is engineered for riders who need durable, consistent power transfer on the street or off-road. Its refined components are developed using computer analysis to help provide higher tensile strength and reliable performance under demanding riding conditions.
Specially controlled heat treatment produces tougher chain materials for increased durability, while the reinforced pins and rollers improve wear resistance, impact resistance, and overall endurance. The BikeMaster Q4 seal ring is designed to reduce friction and help minimize power loss, offering nearly half the friction of a standard O-ring chain. This efficient sealing design helps protect internal components from contaminants while supporting smooth operation and longer chain life.
The BMXR chain is rated for motorcycles with engines up to 1,100cc for street use or 900cc for off-road applications. A rivet-style master link is included for secure installation when properly fitted with the appropriate tools and procedures. Part number BKM197343 provides a direct reference for selecting the correct BikeMaster replacement chain for compatible powersports applications. Always verify chain size, link count, and vehicle fitment before installation.
