1978 Honda CB550K Suspension, Fork and Wheel Fittings

Make lists for the rear shocks, front forks and wheels before choosing parts. This selection contains several shock lengths, individual fork fittings and position-specific wheel components. Compare the installed assemblies first so a model match does not conceal a changed mount, cap, rim or hub.

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

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.
