Rebuild your BSA A65 650 the correct way using our new Hastings piston rings. Hastings rings are the best quality rings you can install in your vintage BSA 650. We use them on many of our builds here at the shop. Hasting rings are made in the USA - all rings are cast iron. Use the drop down menu to select which size rings you need.
Rings will fit original AE / Hepolite pistons or new JCC pistons with no problems. Fits all BSA A650 twins (Lightning, Thunderbolt, Spitfire, Hornet, Firebird Scrambler, etc) from 1962-1972.
