Frame complete
A complete Triumph frame assembly, listed under 83-2985 (also known as F12985).
This is a complete frame, listed in Triumph's own parts book simply as "Frame complete." It's the main structure the whole motorcycle bolts to — engine, gearbox, tank, seat, forks, and swinging arm all hang off this backbone. When a parts book lists a frame as a complete assembly rather than a bare casting, it usually means the part number covers the whole welded unit as it left the factory, ready to receive the rest of the running gear.

The older alias F12985 is the legacy letter-prefix form of this same part number, so if you're working from an earlier book or a part tag stamped with that reference, you're looking at the same physical item as 83-2985.
Our catalog record on this one is thin — just the one listing, tied to the year 1971. We don't have more detail on this one beyond that, so if you're trying to match a frame to a specific model, bring in your numbers or call the shop and we'll work through fitment before you commit to it.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
