1974 Honda CB550K · Fork Parts Buying guide

Compare seals and covers before expanding the fork order

The seal listing gives dimensions, the stock-type gaiters explicitly supply two, and the circlip pack also contains two. Caps and custom boot collars are separate purchases, with different references and mounting details to compare.

Parts to consider

Fork oil-seal setJapanese-made fork seal set, measuring 35 × 48 × 10.5/11 mm. The application explicitly names CB550K0 for 1974; compare the fitted fork before ordering.View part

Spring spacers on the CB550K

The spring listing names two springs, pipe and washers, but explicitly says the spacers and washers are not used on the listed CB550K application. Read its product instructions before planning that spring change. A shared contents list does not make every supplied piece a required CB550K installation part.

Check the damper valve fitment

The damper-valve title names CB550, while its detailed fitment currently lists only CB750 applications. That does not support recommending it here by fork diameter alone. The reflector products serve exterior fittings, and the 35 mm wrench is a tool rather than a replacement fork internal.

Fork questions

How many fork tube bolts are needed?

The cap is sold each, includes an O-ring and states M28 × 1.5 thread. Its usually-two-required note is broader than an exact package count. Compare the original reference and fitted fork before deciding replacement quantities.

Is the alternative gaiter the same stated length?

The alternative description says its black two-piece gaiter set is about 1.75 inches shorter than the stock type. Both reference 51611-300-000, so retain that length qualification when comparing the fitted covers and attachment arrangement.

Which gaiters fit the 1974 CB550K?

The stock-type description names a black set of two, reference 51611-300-000 and the 1974–76 CB550K application. Custom collars have their own 35 mm tube and OEM accordion-gaiter conditions, so inspect the existing upper attachment before combining them.
