BSA Beading, rear, 4 gallon
Rear beading trim for the 4-gallon steel petrol tank, fitted along the seam where the tank meets the twin seat.
This is the rear beading strip for the 4-gallon steel petrol tank, the trim piece that runs along the back edge of the tank where it meets the seat. It's a finishing piece rather than a structural one, dressing up the seam and giving the tank a clean edge where the twin seat sits up against it.

Our catalog shows this one tied to the 4-gallon tank specifically, so if your bike carries a different capacity tank the beading profile likely won't match. It shows up alongside the petrol tank and twin seat figures in the parts books, which tells you it's fitted where those two components meet.
The catalog record we have on this one is brief and doesn't pin it to a specific model beyond noting the 4-gallon tank association, so give us a call and we'll confirm fitment before you order.
Sorry if we got something wrong here. If you think this information isn't correct, .
