This is a genuine Honda black top case. It comes with a nearly unused dedicated bag and the mounting plate (the carrier will be reused, so it's removed). It's a one-key system type, but you'll need to purchase a cylinder separately from a Honda shop. It was mounted on a CB400SB (2022 model), but it was used infrequently, and as the photos show, there are no noticeable scratches or scuffs.
