  New BSA A65 650 Piston & Ring Set. If its that time again to perform a top-end job or a full rebuild we highly recommend installing our new JCC pistons along with a new set of Hastings (USA made) rings. We use this same set-up in our bikes here at the shop with excellent results. Quality is better and even more consistent than the original AE or Heploite pistons. Pistons, pins, clips and rings are all included. Compression ratio is 9:1 - Use the drop down menu to select which size piston and ring set you need.

Fits all BSA 650 Unit twins including the Lightning, Thunderbolt, Hornet, Firebird Scrambler, Thunderbolt, and others from 1962-1972.
