1974 Honda CB125S1 · Engine Drain Hardware Buying guide

Identify the drain fitting before choosing a plug

The magnetic plug is a specific drain-hardware choice within the wider engine range. Use its dimensions and replacement reference to check the fitted drain, particularly if the engine or its threads have been changed.

Parts to consider

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

Keep the order specific to the drain repair

The selected magnetic plug replaces reference 92800-12000, with a 12 mm diameter and 1.5 mm thread pitch. Check these details against the drain on the fitted engine. A previous thread repair or replacement engine may require a different fitting.

Plan the rest of the service separately

The plug’s magnet captures steel debris, but the purchase does not replace the checks required during engine maintenance. Identify the sealing parts needed for the fitted drain and use the correct service information for installation and oil-service specifications.

Buying questions

What measurements should I compare before choosing this plug?

Compare the 12 mm diameter and 1.5 mm thread pitch, then check reference 92800-12000 against the existing part. Inspect the actual drain first if there is evidence of a previous thread repair.

Can I select it by the frame year if the engine was replaced?

Identify the engine and its fitted drain arrangement before ordering. The 1974 CB125S application covers the supported original-model choice; it does not identify the threads or sealing parts on a replacement or modified engine.

What does the magnetic feature do?

The magnet captures steel debris. It is a feature of the replacement drain plug, rather than a diagnosis of engine condition. Follow the correct service information when inspecting the drained oil and planning maintenance.

Not sure which part you need?

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