Complete your BSA 650 top-end job by installing a new set of JCC / Hepolite pistons. We have found JCC / Hepoite pistons to be more consistent than any original or “NOS” piston.

JCC pistons come complete as shown (sold in sets) with pins, clips and pistons. We also offer new Hepolite pistons W/ ring sets in this same listing

Compression ratio is 9:1 which is standard for most applications… Fits all BSA A65 unit twins (Lightning, Thunderbolt, Spitfire, Firebird Scrambler, etc) from 1962-1972.
