1977 Honda CB750K · Headlamp & Parts Buying guide

Plan the headlight order around the parts you can reuse

The stock-style assembly has specific 1977–78 reflector requirements. A sound existing case may need only a plug, mount or adjuster, so inspect the housing and mounting pieces before replacing the complete light.

Parts to consider

Honda CB750 / CB550 / CB500 / CB450 Stock Type Headlight Assembly ~ Replaces 33100-341-701 Stock-style headlight assemblyIncludes a 7-inch halogen unit, rim, retainer and plastic bucket; 1977–78 reflector hardware must be reused or bought separately.View part Honda CB750 / CB550 / CB500 / CB450 Headlight Plug ~ OEM Style ~ Replaces 33130-300-003 Stock-style headlight plugReplacement headlight connector listed for the SOHC CB750K; references 33130-300-003.View part Honda CB750 / CB550 / CB500 Headlight Reflector Rubber Base ~ Replaces 33743-375-000 1977–78 reflector rubber baseIndividual rubber base for the listed headlight reflector mounting; references 33743-375-000.View part

Allow for the late-model reflector hardware

For a 1977–78 CB750K, the stock-style headlight assembly description calls for two existing or separately purchased reflectors, two reflector rubbers and two stay bolts. Inspect these pieces before ordering. The related stay-bolt listing is sold individually and states two bolts are used per bike.

Separate a trim repair from a custom installation

A replacement rim, plug or adjuster can address an individual damaged component while retaining the existing housing. Custom assemblies and fork-mounted brackets introduce their own spacing and diameter requirements. Compare those measurements and the lamp connections instead of assuming every headlight option uses the same mounts.

Questions about headlamp & parts

Does the stock-style assembly include every 1977 mounting part?

Its description specifically asks 1977–78 owners to reuse or separately purchase two reflectors, two reflector rubber bases and two stay bolts. Those requirements should be included in the order plan if the original pieces are missing or damaged.

What comes in the headlight adjuster set?

The linked adjusting set contains one screw and one spring. It is an individual adjuster repair rather than a full headlight hardware kit. Check the condition of the rim, case mounts and other fittings separately.

Are custom fork brackets all the same size?

No. The selection includes brackets specified for different fork-tube diameters and mounting holes. Measure the tubes actually fitted to your motorcycle and compare the bracket description. A custom bracket’s category placement does not establish its fit on replacement forks.

Not sure which part you need?
