Good To Know

Q: Does this 520-112 O-ring chain fit a 1997 to 2003 RM125 without cutting? A: The 112-link length matches the gearing used on these RM125 years, so it installs without shortening. Confirm your rear sprocket tooth count before ordering.

Q: What is the benefit of an O-ring chain over a standard chain? A: The O-ring seals keep factory grease on the pins and rollers while blocking dirt and water. That sealed design typically means longer service life and fewer tension adjustments between rides.

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