Twinseat cover
Outer cover for the Triumph twinseat, the skin that fits over the seat pan and foam.
This is a twinseat cover, the outer skin that goes over the seat pan and foam to give the dual seat its shape and finish. It shows up in the parts book under the GAS TANK AND TWINSEAT figure, so it's the cover portion of the seat assembly rather than the pan or foam underneath.

Catalog records show this number in use for 1974, and it was later superseded by 83-7066, so if you're working from a parts book or an old invoice with 83-4789 on it, know that the replacement part now goes out under that newer number.
If you're re-covering a seat rather than replacing the whole assembly, make sure whatever pan and foam you've got underneath match up with the cover before you commit to stapling it down. Call the shop if you want us to confirm what's correct for your bike before you order.
