The BikeMaster BMZR 520x120 Z-Ring Chain is specifically developed for high-performance sport motorcycles with engine sizes up to 1,200cc. Built for demanding riding conditions, this powersports chain combines high-quality components with a factory-greased seal ring to deliver reliable rigidity, smooth operation, and extended service life. Its black and gold finish adds a distinctive appearance while maintaining the performance expected from a premium replacement chain.
High-tensile steel is used throughout the chain components for increased strength and durability. Larger pins distribute loads across a wider surface area, helping reduce stress on individual components and supporting longer chain life. Specially controlled heat treatment further improves material toughness, making the BikeMaster BMZR chain a dependable choice for sport machines that require consistent power transfer and durable drivetrain performance.
This chain includes a rivet master link for installation. The chain must be correctly matched to the motorcycle’s engine size, power output, and drivetrain specifications. Selecting or installing an incorrectly matched chain may result in chain failure, property damage, serious injury, or death. The installer is responsible for confirming compatibility and completing installation correctly. If you are unsure whether this BikeMaster part number BKM197402 is suitable for your motorcycle or need assistance with rivet-link installation, consult a qualified powersports professional before use.
