1973 Honda CB125S0 · Oil Drain Plug Buying guide

Confirm the drain thread before choosing a plug

Thread size takes priority when selecting a replacement drain plug. Compare the removed plug and drain opening, with particular attention to repairs that may have changed the original thread arrangement.

Parts to consider

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

Use the reference alongside the thread specification

This magnetic plug replaces Honda reference 92800-12000. Compare both the reference and thread specification with the part being renewed. If the engine has been rebuilt or its drain threads repaired, establish the current arrangement before selecting an original-application replacement.

Check the sealing parts before the job

Check the condition and arrangement of the sealing surfaces when planning a plug replacement. Match the seal to the fitted engine and plug, and use the correct Honda service information for sealing and tightening requirements. Treat an altered drain opening as a separate compatibility check.

Buying questions

Can I fit this plug after an oversize drain-thread repair?

Only if the current opening matches the specified 12 mm diameter and 1.5 mm pitch. Establish the repair size first; an oversize or otherwise modified opening may require a different plug.

Is a sealing washer included with the plug?

Washer inclusion is not specified in the product description. Confirm the supplied contents before ordering a separate washer, then match the required seal to the engine and plug arrangement.

Will a new plug solve damage to the drain opening?

Inspect the plug and opening separately before buying. A replacement plug is appropriate only when the receiving thread and sealing arrangement remain suitable; damaged or altered threads need assessment before selecting the repair parts.

Not sure which part you need?

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