Specs At A Glance

Good To Know

Q: Will this chain fit both the TTR125 and TTR125L? A: Yes, the 428-116 sizing covers the listed 2000 and 2001 TTR125 and TTR125L models. Double-check your gearing if you have changed sprocket sizes.

Q: Does an O-ring chain need frequent lubrication? A: The O-rings retain factory grease inside the links, so lubrication intervals can be longer than with a standard chain. Light oil on the rollers still helps resist rust and wear.

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