PISTONS A65 +.080 JCC TWN
An A65 +.080 oversize piston for BSA A65 twin rebuilds, also listed as 18-89318.
This is a piston for the BSA A65 twin, listed in the +.080 oversize. The A65 is a BSA model, not a Triumph, so if you're working on a Triumph engine this one isn't for you. It's a rebore-size piston, meaning it's meant for a cylinder that's already been bored out .080 over standard to clean up wear or damage.
