FAQs
What does the 525 designation mean?
525 refers to the chain pitch and width, which is the standard size compatible with specific motorcycle sprocket widths.
Can I use a clip-style master link instead of the rivet link?
For safety and performance, the RK 525 ZXW is designed to be used with the included rivet link. Using a clip link is not recommended for this high-strength chain.
How often should I lubricate the chain?
It is recommended to clean and lubricate every 300 to 500 miles, or immediately after riding in wet or dusty conditions.
Is this chain compatible with all motorcycles?
No, it is specific to motorcycles requiring a 525 pitch chain. Always check your motorcycle's manual for the correct chain size and length.
Why is the chain colored red?
The red finish is a cosmetic choice that also provides an extra layer of protective coating to the exterior plates.
Troubleshooting
Chain making noise during operation
Check chain tension and ensure it is lubricated correctly. Inspect sprockets for signs of shark-finning or wear.
Excessive chain slack
Adjust tension according to your motorcycle owner's manual. If it cannot be tightened, the chain may be stretched beyond its service limit.
Stiff links
Clean the affected area thoroughly and apply chain lubricant. Work the link back and forth manually; if it remains stiff, replace the chain.

Setup, Compatibility & Care
Proper installation of the 525 ZXW/112 is critical for safety. You must use a dedicated chain rivet tool to flare the hollow pins on the master link according to the manufacturer's specified tension settings. Before installation, ensure your motorcycle's sprockets are in good condition, as worn sprockets will rapidly damage a new chain. For maintenance, clean the chain using a mild detergent and a soft brush, followed by the application of a high-quality motorcycle chain lubricant specifically designed for sealed chains. Avoid using high-pressure washers directly on the chain, as they can force water past the XW-rings and cause internal corrosion.
