1975 Honda CB550F · Fork seals, springs & boots Buying guide

Choose fork service parts by dimensions and boot design

Fork seals, retaining rings, caps and gaiters serve separate locations. Compare each worn piece before ordering, and keep the CB550F spring fitting notes separate from the spacer instructions for other Honda models.

Parts to consider

Stock-type black fork gaitersSet of two stock-type gaiters for the 1975–76 CB550F. Replaces reference 51611-300-000.View part

Compare the two gaiter options

The featured stock-type gaiters and the linked shorter gaiters are both supplied as sets of two for the 1975–76 CB550F. The shorter version is approximately 1.75 inches shorter than the stock-type design. Compare the attachment points and needed coverage before choosing between them, especially with changed headlight mounts.

Follow the CB550F spring notes

The linked progressive-type spring set contains two springs, a ten-inch pipe and washers. Its CB550F application specifically does not use the supplied spacers or washers. Do not apply another model’s pipe-cutting instructions to this bike; check the product instructions and the Honda manual for the installed fork assembly.

Fork Seals, Springs & Boots FAQs

Are retaining rings supplied with the fork seals?

The seal set and retaining-ring pack are separate products. The ring pack contains two metal rings that fit above the seals, replacing reference 51447-KL4-951. Inspect the old rings and order the pack separately if replacements are needed.

Should I cut the included pipe into CB550F spring spacers?

The linked spring product specifically says its spacers and washers are not used with the CB550F. Follow that model-specific note and the installation instructions rather than assuming the supplied pipe is needed on every listed Honda application.

Does the replacement fork cap include its O-ring?

The linked aftermarket cap replaces reference 90123-300-000 and includes its O-ring. It is sold individually and has an M28 × 1.5 thread. Compare the installed cap and fork assembly, then order the quantity required for your service.
