The BikeMaster BMZR 520x120 Z-Ring Chain is designed for high-performance sport motorcycles with engine sizes up to 1,200cc. Built for demanding riding conditions, this motorcycle chain combines high-quality components with a factory-greased seal ring to provide strong rigidity, reliable sealing, and extended service life. Its black and chrome finish adds a distinctive appearance while maintaining the performance expected from a premium powersports chain.
High-tensile steel is used throughout the chain components for increased strength and durability. Larger pins distribute loads across a wider area, helping reduce stress and support longer chain life under demanding acceleration and riding conditions. Specially controlled heat treatment further strengthens the material, improving resistance to wear and fatigue. The chain includes a rivet-style master link for a secure installation when properly fitted with the appropriate tools.
Before installation, verify that the chain is correctly matched to the motorcycle’s engine size, power output, sprocket combination, and manufacturer requirements. Improper chain selection or installation may result in chain failure, property damage, serious injury, or death. The installer is responsible for confirming compatibility and completing installation correctly. Consult a qualified powersports professional if you have any questions about selecting, riveting, or maintaining the chain. The BikeMaster BMZR part number BKM197401 is intended for compatible sport motorcycle applications and should be serviced according to the motorcycle and chain manufacturer’s recommendations.
