Choose a CB550K year and code

The catalog’s year sequence is CB550K0 (1974), K1 (1975), K2 (1976), K3 (1977) and K4 (1978). Choose the matching year page before comparing parts.

The CB550F range overlaps 1975–1977; CB550SC Nighthawk is a separate 1983–1984 group. Keep the K suffix in your search to avoid mixing these model pages.

1974 CB550K0

1975 CB550K1

1976 CB550K2

1977 CB550K3

1978 CB550K4

Review the details of each item

A part listed for one K year may have a narrower fitment range than this collection. Check its stated years and any supplied reference number, then compare the dimensions or fittings relevant to the replacement.

When a listing omits the K version or year, resolve that detail before ordering. Package contents and quantities should be checked on the same product page.
