Specs At A Glance

Good To Know

Q: Does this chain come with a master link? A: Most O-ring chains in this configuration ship with a clip-style master link for installation. Check the listing details and photo to confirm what is included in the package.

Q: How often should I adjust chain tension after installing it? A: New chains stretch slightly during the first few rides, so check tension after the first hour of use and again after a couple of rides. Adjust to the free-play spec in your TTR125 service manual.

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