Specs At A Glance

Good To Know

Q: Does this chain fit every model year of the RM125? A: It is listed for the 1983, 1985, and 1986 RM125 only, so other years or models may need a different length or pitch. Q: Should the chain be replaced together with the sprockets? A: Replacing sprockets at the same time is common practice because a worn sprocket can quickly damage a new chain.

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