1978 Honda CB550K · Suspension & Wheel Buying guide

Build the order around the assemblies on the motorcycle

Measured shock mounts, fork part references and wheel position identify different choices. Check each assembly independently, then compare package contents so tools, seals, supports and complete sets do not get confused in the repair order.

Parts to consider

Honda CB Stock Type Shock Absorber Set ~ Chrome 321mm 321 mm stock-style chrome shock setChrome set without upper shrouds, listed at 321 mm eye-to-clevis with a 20 mm upper-eye width. Compare the installed dimensions; the stock-style name is not proof of factory height.View part Honda CB900 / CB750 / CB650 / CB550 Front Fork Oil Lock Piece ~ Genuine Honda 51432-371-003 Genuine Honda internal fork oil-lock pieceHonda 51432-371-003, sold individually and identified for the front-fork assembly. Match the old piece and fork diagram rather than treating it as a universal internal fitting.View part 1977-78 Honda CB550F / CB550K Rear Wheel Spoke Set Rear spokes with silver nipplesSet for the listed stock 18-inch rear-wheel application, containing 40 silver spokes and 40 silver nipples. Compare any replacement rim or hub before choosing it.View part

Choose shock length before cosmetic details

The stock-style shock descriptions include different stated lengths, so measure the fitted units rather than selecting by name or finish. Compare eye-to-clevis versus eye-to-eye mounts and any listed upper-eye dimensions. The shorter custom sets should be evaluated as custom choices instead of assumed stock replacements.

Treat wheel and fork contents independently

The rear spoke set includes its stated spokes and nipples, while fork dust boots, oil seals and retaining rings are separate products. Check the pieces needed at each assembly. The genuine oil-lock piece belongs inside the fork and should not be confused with a swingarm or shock bushing.

Common questions

Does stock-style shock wording establish the correct height?

No single factory height can be established from the differing stock-style names. Compare the stated length and measurement endpoints with the shocks currently fitted, then check upper and lower mounting details before choosing a set.

Does the fork oil-lock piece fit every similar Honda fork?

Its description specifically calls for comparing the original piece, fork diagram and Honda reference. Similar-looking forks can have different internals, so the 51432-371-003 application should be checked against the assembly actually on the motorcycle.

Are front and rear wheel parts one combined service set?

The spoke sets, seals, bearing and retainers are separate products with their own positions and contents. Identify the wheel being repaired, then compare each needed piece instead of expecting a complete service package from one purchase.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
