1975 Honda CB550K · Forks Buying guide

Restoring the front end

Match the component to the fork assembly actually fitted. The listings cover seals, springs, gaiters and small hardware separately, and the spring package has a specific CB550 instruction excluding its supplied spacers and washers.

Parts to consider

Progressive fork spring pairTwo springs supplied with pipe and washers; the listing says the spacers and washers are not used on CB550K models.View part

Honda CB Stock Type Fork Gaitors ~ Replaces 51611-300-000

Two gaiter options

Both gaiter listings reference Honda 51611-300-000 and name the 1974–76 CB550K. One is described as stock type; the other is about 1.75 inches shorter. Compare the fitted gaiters and attachment points before choosing a length, especially where the headlight mounts have changed.

Damper valves do not list the 550

The front fork damper valve set carries this tag, but its fitment names only 35mm forks on CB750 models. Ask the store whether it suits a 1975 CB550K, as the description lists no 550 application at all and none should be assumed.

Common questions

Are the supplied spring spacers used on the CB550K?

The package contains two springs, pipe and washers. The listing explicitly says the spacers and washers are not used on the listed CB550K and CB550F applications. Follow the supplied instructions for the identified fork assembly.

Does the fork cap bolt come with an O-ring?

The fork cap listing includes an O-ring and references Honda 90123-300-000. It describes a 35 mm fork-tube application; compare the fitted cap, thread and fork arrangement before selecting this replacement.

Why are reflectors in the fork section?

Reflectors and their rubber bases are listed elsewhere for the motorcycle’s front mounting area. They are separate from the internal fork components; use the signal and reflector guide to compare the appropriate references.
