Good To Know

Q: How often should a drive chain be replaced? A: Replace it when links bind, the chain stretches beyond the adjustment range, or sprocket teeth show hooking. Regular lubrication and correct tension will extend its service life.

Q: Do I need to cut this chain to length? A: If the link count matches your MX125 setup, it installs as-is with a master link. Double-check your sprocket sizes before cutting anything.

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