Product Information

Full details

The RK Standard 520 Chain (96 links) is designed for motorcycle enthusiasts and riders seeking a lightweight, high-performance drive system for sporting applications. Its O-Ring-free construction delivers an efficient power transfer, making it an excellent choice for riders who prioritize a responsive feel over long-distance touring. Please note that because it lacks O-Rings, this chain requires more frequent lubrication and maintenance to prevent wear compared to sealed-ring alternatives.

FAQs

Can I use this chain on a street-touring bike?

While it will function, it is not recommended for high-mileage touring because it requires significantly more frequent maintenance than an O-ring or X-ring chain.

Does this chain come with a master link?

Yes, it typically includes the necessary master link for installation.

How often should I lubricate this chain?

For optimal performance and to prevent rust, lubricate every 300 miles or immediately after riding in wet conditions.

Is 3100kg tensile strength enough for my bike?

This strength is sufficient for most medium-displacement sport motorcycles. Check your owner's manual to verify the chain requirements for your specific model's engine power.

Can I cut this chain to fit a shorter motorcycle?

Yes, standard chain breakers can be used to remove excess links if your motorcycle requires fewer than 96 links.

Troubleshooting

Chain making a grinding noise

The chain is likely dry or misaligned. Clean, lubricate, and verify your rear wheel alignment using the swingarm indicators.

Excessive slack or sagging

Adjust the rear axle position to take up the slack. If the adjustment bolts are at their limit, the chain has stretched beyond its service life and must be replaced.

Pros and Cons

Pros

  • Lightweight design enhances throttle response
  • High tensile strength of 3100kg for durability
  • Lower frictional drag due to O-Ring-free construction
  • Cost-effective solution for sport-oriented maintenance

Cons

  • Requires more frequent cleaning and lubrication than sealed chains
  • Less resistant to dirt and debris ingress
  • Shorter lifespan in harsh weather conditions

Setup, Compatibility & Care

To ensure proper performance, verify that your motorcycle's sprocket pitch matches the 520 specification. When installing the 96-link chain, ensure the rear axle is positioned to allow for proper tension adjustment, typically allowing for 20-30mm of slack in the center of the bottom run. For maintenance, clean the chain every 300-500 miles using a dedicated chain cleaner and a soft brush. Follow this immediately with a high-quality non-O-ring compatible chain lubricant. Because this chain lacks internal seals, it is susceptible to corrosion; keeping it well-coated in lubricant is essential for longevity.
