1975 Honda CB400F Seat Lock with Keys

This is a seat lock, not a helmet lock and not a rim lock. Keys are included, with no count printed. The body sits a bit farther out, and a lost key means a 10mm wrench on the bracket.

1975 Honda CB400F · Rim, Helmet & Seat Locks Buying guide

Keys are included. The reach is not identical.

Buy it when the cylinder or the key has failed. Expect the new lock to sit slightly farther out. The description does not say it locks a helmet or a wheel.

Parts to consider

Honda CB Seat Lock with Keys ~ Replaces 77230-399-007 Seat lock with keysReplaces 77230-399-007 and 77230-107-711. Keys come with it. The lock body sits slightly farther out than the original. Names the 1975-77 CB400F.View part

What changes under the seat

The description says the locking mechanism sticks out a bit farther than the original, and that it still works on the bikes it names. Look at the clearance under your seat. If the old key is lost, remove the seat-lock bracket with a short 10mm wrench or socket, then fit the new lock.

Not every lock in the category name

The category title mentions rim and helmet locks. This product is the seat lock. It will not replace a fork lock or a helmet holder.

Seat lock questions

Are keys included?

Yes. The description does not print how many. It replaces 77230-399-007 and 77230-107-711, and it names the 1975-77 CB400F.

Will it sit exactly like the original?

No. The mechanism sticks out slightly farther than the original. Check clearance under the seat.

What if the old key is lost?

Remove the seat-lock bracket and assembly with a short 10mm wrench or socket. The description says the rest of the swap is then straightforward.
