The T20 is one of Triumph's smaller unit-construction machines, and the .070 overbore designation tells you this piston is meant for a cylinder that's already been bored out that extra amount over stock, typically to clean up wear or damage on a previous rebuild. Make sure your barrel has actually been bored to match before ordering, since a mismatched size won't seat right.
We don't have much more detail on file for this one beyond the catalog listing itself. If you're not sure whether your barrel is standard or already oversized, give us a call with your specs and we'll help you sort out what you need.
