Good To Know

Q: What chain length is recommended with this sprocket? A: Use the stock chain length for your model; a 49 tooth sprocket may require a longer chain if changing from a smaller sprocket, so check your chain slack.

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