1975 Honda CB400F Seat Cover and Lock

A seat cover does not include the lock or the pan. The lock body is not identical in reach to the original. A mounting rubber in this category is an air-cleaner rubber on this bike, not a seat rubber.

1975 Honda CB400F · Seat Covers & Hardware Buying guide

Skin, lock, and bar are separate

Buy the cover when the vinyl is torn. Buy the lock when the cylinder or the key has failed. Buy the bar when that rod is bent. None of them is the seat base.

Lost key, then a 10mm wrench

The lock text says a lost key means removing the seat-lock bracket and assembly with a short 10mm wrench or socket. After that, the rest of the swap is straightforward. The new lock still sits slightly farther out. Check clearance under the seat.

One rubber here is not a seat rubber on this model

The mounting rubber replaces 17245-107-010. On the CB350F and CB400F it is the air-cleaner housing rubber. The seat setting rubber is the genuine part 77204-312-000, and that one does name the 1975-77 CB400F.

Seat questions

Does the cover include the seat pan?

No. It is a cover for the 1975-77 CB400F stock seat, with no hardware and no Honda stencil.

How many keys come with the lock?

The text says keys are included and does not print a number. It replaces 77230-399-007 and sits slightly farther out than the original.

Is the lock bar the same part as the lock?

No. The bar replaces 77220-340-003. The lock is the cylinder with keys.
