1974 Honda CB550K · Seat Buying guide

Check the retained seat before selecting cover or hardware

The cover is intended for the original stock seat, with hardware and chrome trim reused. A lock bar and hinge pins address separate components; the two rubber references require comparison with the actual underside support.

Fitting a seat cover

The cover includes installation and damaged-foam repair instructions, with no hardware or chrome trim supplied. Its installed-seat photograph shows Honda lettering, while the description explicitly says no rear Honda stencil is supplied. Confirm that supplied appearance and retain the existing trim and fixings.

Two seat setting rubbers

Two genuine Honda seat-setting rubbers are listed with different references, 77204-312-000 and 77204-292-000. Both include the 1974–78 CB550K, and both are sold individually. Compare their shapes and the fitted support locations before choosing either; the descriptions do not establish that they are interchangeable.

Seat questions

Does the seat cover fit the 1974 CB550K?

The listing identifies the original stock 1974–76 CB550K seat and a reinforced passenger strap. It supplies a cover with a foam layer sewn into the top, not a complete seat, hardware or chrome trim.

How many seat hinge pins are needed?

The hinge-pin description states two used per bike, with reference 77103-313-000. That usage note is separate from the quantity supplied in an order. Inspect the hinges and count the pins needing replacement before purchasing.

Does the lock bar fit the 1974 CB550K?

The lock-bar assembly description includes the 1974–78 CB550K and references 77220-340-003 and 77220-340-011. Compare the actual latch component being replaced; the cover, hinge pins and setting rubbers have their own separate listings.
