Hinge
The seat hinge (83-2867) that lets the twinseat pivot up for access to the battery and toolbox.
This is the seat hinge, 83-2867, listed under the twinseat and chainguard/silencer figure in the parts books. It's the pivot point that lets the seat swing up so you can get at the toolbox, battery, and electrics underneath. The legacy F12867 number is the same physical piece if you're cross-referencing an older parts book.

Other catalogs list this same number as fitting T120, T140, and A65 seats, so it's clearly a hinge that carried across more than one marque's twinseat setup. Our own catalog record only ties it to 1971-1972 appearances, so if you're matching an earlier or later seat, check the hinge design against what's on the bike before ordering.
It's a simple wear item — hinges get sloppy or bent over the years from riders leaning on the seat or hauling it up and down. Worth a look if your seat doesn't sit tight or latch properly at the back.
