Buyer's guide
- Check the chain size code (such as 428, 520 or 525), pitch and link count for the motorcycle.
- Confirm front and rear sprocket tooth counts match the stock or intended gearing.
- Look for the seal type, plain roller, O-ring or X-ring, and the chain's tensile strength.
- Check sprocket material and tooth hardening.
- Ask for the exact motorcycle model and year the kit is made for.
- Ask whether a connecting link, clip or rivet type, is included.
