RK RECOMMENDED CHAIN APPLICATIONS
Always replace your chain with the same size/grade/type of chain that came stock on the bike from the factory.
If a motorcycle came from the factory with an endless chain, we recommend that RK replacement chains be installed with an RK Rivet type connecting link and press-fit tool.
A Wear Life Index is a way to compare one chains probable life to another under identical circumstances. A higher number indicates longer chain life.
