Identify timing, float and brake components

The float-and-pin assembly replaces 16013-439-921 and is sold each for the listed 1984–85 CB125S. Rear brake shoes are specified as 109.5 mm diameter × 25 mm width. Compare the float arrangement and rear-brake assembly with the fitted components.

Fitment questions

Does the cam chain include a joining link? Yes. The chain is supplied with a clip link. Use the appropriate service-manual procedure for the repair.

Does an OEM reference mean the part is genuine Honda? Not by itself. Aftermarket parts can quote the Honda number they replace. Look for an explicit genuine Honda description if brand origin matters; “OEM-type” or “replaces OEM” does not identify the manufacturer.
