1978 Honda CB550K · Frame & Body Buying guide
A missing emblem, torn seat covering and damaged chain guard need different purchases. Identify the retained base or mounting arrangement first, then account for the separate rubbers and hardware around the replacement.

The photograph shows a complete installed seat with HONDA lettering and trim. The purchase is only the replacement cover for the original 1978 seat, with strap and top foam. Hardware, chrome trim and the Honda stencil are excluded; confirm supplied artwork before ordering.
An emblem supplies its two clips, while side-cover dampers are individual rubber purchases. Inspect the panel, retained trim fittings and cushions together before checkout. For a chain guard, compare its mounting points with the actual swingarm and confirm any missing fasteners separately.
The seat product supplies the cover rather than a complete seat. Its application is the original stock 1978 seat, and hardware and chrome trim are excluded. Assess the existing seat base and fittings before ordering.
The emblem comes with two attachment clips, not a complete side-cover mounting rubber set. Damper A and damper B are separate individual products; compare the retained rubbers and count the replacements needed.
Compare the installed swingarm and guard attachment points first. The guard’s buyer notes specifically call for checking changed swingarms and rear suspension arrangements; the model application alone does not establish the custom mounting pattern.
