BikeMaster 520x130 BMZR Z-Ring Chain
This is the longer BMZR chain option for riders who need more adjustment room or are running gearing that pushes a standard chain to its limit. The BikeMaster 520x130 BMZR Z-Ring Chain is commonly used on higher-output sport bikes, stretched setups, or situations where a 120-link chain simply isn’t enough.Both versions are the same chain mechanically. The only difference is the finish—Chrome or Gold.Use and fitment notes
A 130-link chain usually comes into play when axle blocks are near the end of their range or when sprocket changes add length. Rather than forcing a shorter chain to work, this size gives you flexibility during setup. It’s still critical to confirm pitch, length, and compatibility with your bike’s power level. Chain choice is one of those areas where close enough isn’t good enough.How this chain holds up in use
The BMZR Z-Ring design is about keeping wear under control. The seals lock factory grease around the pins, which is where most chains fail first. Once that grease is gone, stretch shows up fast. From experience, this is what tends to stand out:- Z-Ring seals slow down internal wear and help the chain stay consistent
- Larger pins handle torque better under hard acceleration
- Heat-treated steel plates resist elongation over time
- Adjustment intervals are longer compared to basic sealed chains
- Rivet-style master link is better suited for higher-load applications

Materials and build quality
High-tensile steel is used across the chain components, paired with controlled heat treatment to balance strength and durability. This matters more in long-term use than raw tensile numbers. The goal is predictable wear, not just surviving a pull test.As with any chain, sprocket condition and alignment play a big role in lifespan.Installation and safety considerations
This chain must be correctly matched to the motorcycle’s size and power output. Improper selection or installation can lead to chain failure, which can cause serious injury, death, or damage.If you don’t regularly cut and rivet chains, installation should be handled by a qualified technician.3 reviews for BikeMaster 520×130 BMZR Z-Ring Chain

Great 520 chain for dirt bikes or lightweight sportbikes. Z-ring sealing is a big upgrade from standard.
Jacob S –
Fitted perfectly on my 520-spec bike. Chain runs smooth and quiet with good lube retention.
Heather Levine –
Solid chain at a fair price. The z-ring design is worth it for the reduced maintenance.
