1979 Honda CB125S · Engine Service Parts Buying guide

Build the service order around the identified opening

The pictured plug replaces 92800-12000 and has a 12 mm diameter with 1.5 mm thread pitch. Use both measurements when comparing it with the drain connection already fitted.

Parts to consider

Honda CB Magnetic Oil Drain Plug Magnetic drain plug12 mm diameter, 1.5 mm thread pitch; replaces 92800-12000.View part

Separate a damaged fastener from a damaged opening

Inspect the plug together with the threaded opening that receives it. Damage to the receiving thread or sealing face needs its own assessment. A replacement plug should be selected against the existing connection; the catalogue diameter alone cannot establish the condition of that connection.

Keep the magnetic feature in perspective

The plug is described as capturing steel debris. That feature does not establish a diagnosis or a different service interval. Use the appropriate service information for the oil service and for assessing any material found during inspection, rather than treating a magnetic plug as a repair for internal wear.

Buying questions

Does the replacement reference identify a genuine Honda plug?

The product is a magnetic replacement for 92800-12000. The reference identifies the part it replaces; it does not establish Honda-branded manufacture. Choose it for the stated replacement specification and magnetic feature.

Will it repair a stripped drain opening?

Have damaged receiving threads assessed separately. The plug has a specified 12 mm diameter and 1.5 mm pitch, but a matching nominal thread does not repair a damaged opening or sealing face.

What should I confirm before combining it with other service parts?

Identify the drain connection and the sealing part required for the planned service. Included sealing hardware is not specified for this plug, so confirm that item rather than assuming the order supplies a complete oil-service kit.

Not sure which part you need?

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