1984 Honda CB125S · Oil Service Parts Buying guide

Check the plug thread and the sealing surface

Reference 92800-12000 identifies this magnetic plug. Match the thread and seating arrangement with the fitted engine, and settle any washer requirement before the motorcycle is opened for service.

Parts to consider

Honda CB Magnetic Oil Drain Plug Magnetic oil drain plugA magnetic drain plug specified as 12 mm × 1.5, with replacement reference 92800-12000. Match the removed plug and its sealing arrangement before ordering.View part

Plan the seal along with the plug

A correct thread does not settle the sealing-washer choice. Compare the existing seat and washer, then confirm whether a washer accompanies this plug. Its description does not specify washer supply, so resolve that detail before buying an additional seal.

Treat the magnet as a collection feature

The magnet collects steel debris at the drain fitting. It is not a substitute for oil-system maintenance or an explanation of any debris found. Use the engine’s service information for inspection and have unusual metal debris assessed rather than relying on the new plug to address its cause.

Common buying questions

Should I order a new washer with this plug?

First confirm what accompanies the plug; its description does not specify a supplied washer. Compare the required seal with the existing seating arrangement so you order the correct sealing piece without duplicating anything included.

What does M12 × 1.5 tell me when comparing plugs?

It identifies the offered plug’s 12 mm thread diameter and 1.5 mm pitch. Check both against the removed fitting, then compare the seating arrangement separately; the thread designation does not describe the sealing washer.

What should I check if the old plug has damaged threads?

Have the plug and the engine opening assessed together before ordering. Establish whether the problem is limited to the removable fitting or involves the engine threads, because that changes the repair and the replacement specification.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
