BSA BASE GASKET A65 (UK)
Base gasket for the BSA A65 twin, sealing the joint between crankcase and cylinder barrel.
This is a cylinder base gasket for the BSA A65 twin. It seats between the crankcase and the base of the barrel, sealing that joint so oil and combustion pressure stay where they belong. The catalog record on this one is brief and shows no history of prior appearances, so treat it as a straightforward base gasket rather than a part with a lot of documented backstory.

Another catalog listing ties this same gasket to the A50-A65 base coverseal family, which lines up with it being a BSA part rather than anything Triumph. If you're rebuilding an A65 top end, this is the gasket that goes down before the barrel goes back on.
