BSA A50 PISTON SET .020
A .020 oversize piston set for the BSA A50 unit twin, also catalogued as B160.
This is a piston set for the BSA A50, sized at .020 over standard. It's listed in our records under the JRC part number as well as the older B160 designation, so if your parts book shows one or the other, you're looking at the same set.

The A50 is a BSA unit twin, not a Triumph, so if you've landed on this page while sorting parts for a Triumph engine, double check you've got the right bike before ordering. A .020 oversize set is meant for a bore that's already been taken out that amount during a rebuild, so this isn't a standard-bore piston.
We don't have extra detail beyond what's in the catalog listing on this one. If you need confirmation on ring count, pin size, or compression height before you commit to the purchase, give the shop a call and we'll sort it out with you.
