Our catalog record on this one is brief. It shows up in the GAS TANKS figure with a 1970 date attached, but that's about as much detail as we've got on file. Given how many variations Triumph ran through on tank shape, badge mounts, and knee pad fixings across those years, don't assume this one is a drop-in match without checking it against your bike.
If you're trying to match this to a specific model or tank style, give the shop a call and we'll talk through what you've got before you order.
