1974 Honda CB125S1 Lighting Hardware

For a lighting-hardware repair on the 1974 Honda CB125S1, first identify whether the worn part seals a signal lamp or attaches to a reflector bracket. The gasket and screw-on reflector need different mounting checks, especially on a previously restored motorcycle.

1974 Honda CB125S1 · Lighting Hardware Buying guide

Separate the lamp seal from the reflector fitting

A sound signal housing can remain in use with the correct replacement gasket. A reflector instead needs a compatible threaded attachment. Inspect the affected assembly before choosing either small hardware replacement.

Parts to consider

Match the installed lens and lamp housing.View part Honda CB Stock Type Reflector ~ Replaces 33741-340-670 Screw-on reflectorStock-type reflector with a specified 6 mm mounting thread. Check the bracket and clearance before ordering.View part

Inspect the signal before selecting its seal

Check the lens, housing and their sealing surfaces before choosing the separate gasket. Reference 33443-268-671 identifies the replacement seal. When a different signal assembly has been installed, match its gasket shape and attachment rather than relying on the motorcycle year alone.

Separate lamp sealing from reflector mounting

The signal gasket belongs to a matching lens and housing, while the screw-on reflector requires a suitable threaded bracket. Check these mechanical details independently. A replacement lamp or bracket fitted during restoration can change the part needed even though the motorcycle’s identity is unchanged.

Buying questions

Can a gasket refresh leave the existing signal lamp in place?

Yes, if the lens and housing are serviceable and use the matching seal. Compare their sealing shape with reference 33443-268-671 first; a damaged housing or changed lamp assembly may require a different repair.

Is a 6 mm mounting hole enough to confirm fit?

Check the bracket’s thread and available mounting clearance as well. The product specifies a 6 mm thread but does not state its pitch or usable length. Confirm those details against the installed bracket before ordering.

How should I plan an order for both sides of the motorcycle?

Identify the worn gasket and reflector positions separately, then confirm the supplied quantity for each product before ordering multiples. The two parts are separate choices; their appearance in one guide does not make them a paired 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.
