Twinseat
Twinseat for Triumph, catalog part 83-4288, later superseded by 83-3634NL.
This is the twinseat listed under Triumph part number 83-4288, shown in the parts book alongside the gas tanks in the GAS TANKS AND TWINSEAT figure. It's the seating surface that sits over the rear frame section behind the tank, shared by rider and passenger on the bikes it was cataloged for.

The part number was later superseded by 83-3634NL, so if you're cross-checking an old parts book or a seat that's been kicking around a while, you may see either number used for what is the same physical seat. The F14288 form you'll sometimes run across is just an older alias for the same listing.
Our record on this one only ties it to a single catalog appearance for 1972, so we don't have a wider fitment span to point to. If you're trying to match this to a specific tank or frame, bring in what you've got or give us a call and we'll confirm before you order.
