1976 Honda CB125S3 — Filtres à huile, bouchons, pompes et manomètres

The description does not specify supplied sealing hardware. Confirm the package contents and the sealing piece required by the fitted drain before completing the order, rather than inferring an included washer from the image.

Check the pitch as well: this plug is 12 mm in diameter with a 1.5 mm thread pitch. If an earlier repair changed the drain, use the actual receiving thread rather than the motorcycle year alone.

Its stated purpose is capturing steel debris. Keep that function separate from the rest of the oil-service work, and use the motorcycle’s service information for inspection and maintenance rather than assuming the magnet replaces those checks.
