1977 Honda CB550K Headlamp & Mounting Parts

The 1977 Honda CB550K headlamp category covers the assembly, bucket, rim hardware, adjuster and mounting pieces. A larger assembly can simplify the parts list, but this model’s listing still calls for separate side reflectors, their rubber bases and mounting bolts.

1977 Honda CB550K · Headlamp, Bulbs & Parts Buying guide

Check what stays with the headlight

Choose a complete assembly only after comparing its contents with the usable parts on your bike. Separate bucket and retaining parts suit a smaller repair without assuming the existing lamp unit also needs replacement.

Parts to consider

Honda CB750 / CB550 / CB500 / CB450 Stock Type Headlight Assembly ~ Replaces 33100-341-701 Stock-type headlight assemblyAssembly with a 7-inch halogen unit, rim, retainer and plastic bucket.

Distinguish the assembly from its attachments

The headlight assembly lists a 7-inch halogen unit, rim and retainer, plastic bucket, cables and hardware. Its CB550K 1977–78 note directs you to reuse or separately buy the side reflectors, rubbers and stay bolts. Check those pieces before treating the assembly as the whole job.

Retain the parts that still match

A bucket is available separately, as are the rim retainer and the adjuster screw-and-spring set. Compare the damaged component and its surrounding hardware before ordering. Custom bracket choices need a measured fork-mount comparison; a bracket’s stated diameter is not proof that it matches your motorcycle.

Common buying questions

Are the side reflectors included with the assembly?

The assembly’s note for the 1977–78 CB550K says to reuse the existing side reflectors, their rubber bases and stay bolts or purchase them separately. Count and inspect those installed pieces before ordering the assembly and its additional attachments.

What does the adjusting screw set contain?

The adjuster set lists one screw and one spring. It is an individual adjustment-hardware purchase, not a lamp assembly or mounting kit. Compare both original pieces and the replacement references provided in its listing.

Can I replace the bucket without buying the whole headlight?

The black stock-type bucket has its own listing. Compare its shell and mounting arrangement with your existing headlamp, then check the separate rim and retaining parts. A bucket purchase does not establish that the other lamp pieces are included.

Not sure which part you need?
