PISTON SET NORTON 500/020

We don't have much more detail on file for this one beyond the catalog listing itself. It's not a Triumph part - the description is specific to the Norton 500 engine family - so don't confuse it with any of the Triumph piston sets we carry.
Give us a call before you order to confirm this matches your bore size and engine spec. We'd rather nail down fitment on the phone than have you send something back.
