That's a BSA part, not a Triumph one, so if you're wrenching on a Triumph twin this isn't your piston. It's worth double-checking the number against your own parts book or your engine's bore size before ordering, since piston sets are matched to specific bore dimensions and we don't have that spelled out on our end for this listing.
We don't have much more detail on file for this one beyond the basic description. Give us a call and we'll help confirm it's the right set before you commit.
