Specs At A Glance

Good To Know

Q: Does this chain come with a master link? A: The chain is supplied as a 108-link length, and you should confirm whether a connecting link is included with your order before installation.

Q: Should I replace my sprockets at the same time? A: Replacing the chain and sprockets together is common practice because a worn sprocket can rapidly wear out a new chain.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
