1972 Honda CB500K Seat Locks, Cushions & Covers

Seat work on the 1972 CB500K may involve locking hardware, hinge pieces, mounting cushions or upholstery. Inspect the seat base before selecting the part. A replacement cover reuses existing hardware, while the lock bar and genuine Honda rubbers have their own separate applications.

1972 Honda CB500K · Seat Covers & Hardware Buying guide

Identify the seat problem before choosing its replacement

The lock bar’s stated CB500K application begins with 1972, while the cushion references distinguish separate rubber profiles. Check which fitted component needs repair; the seat-cover photograph is a reference view of an installed seat, not the supplied complete assembly.

Check the lock and hinge as different repairs

The seat lock bar assembly references 77220-340-003 and 77220-340-011, while the hinge pin references 77103-313-000. Both descriptions support the 1972 CB500K application. Match the part to the damaged position on the existing seat; a lock bar does not replace a hinge pin or an upholstery covering.

Read the upholstery contents before removing the old cover

The stock-seat cover includes a reinforced passenger strap and installation instructions. Hardware and chrome trim are excluded, and the source explicitly says the supplied cover has no Honda stencil. Inspect those retained parts and the seat base first, because the installed-seat photograph does not show everything one order provides.

Choosing the right parts

Are the two Honda cushion references interchangeable?

No interchange is established between 77204-292-000 and 77204-312-000. Each is individually supplied for its matching seat support. Choose by the original rubber profile and mounting position, particularly when the pan or mounting hardware has changed.

Does one hinge-pin order supply the two used on the motorcycle?

One 77103-313-000 pin comes with an order; two are needed for both seat hinges. Inspect the hinge brackets, holes and retainers as well, then order for the pin locations actually being replaced.

Will the replacement cover fit a changed seat pan or reshaped foam?

It is patterned for the stock CB500K pan and foam, and has no rear Honda stencil. Modified foam or an aftermarket pan may change fit. Chrome trim and mounting hardware are excluded and reused only if serviceable.
