RING SET NORTON 500+.060
Piston ring set for the Norton 500 twin, sized .060 over standard bore.
This is a ring set for the Norton 500 twin, sized at plus .060 over standard bore. That oversize figure tells you it's meant for a cylinder that's already been rebored .060 inch over, so check what your barrels measure before ordering.

This isn't a Triumph part - it's cataloged specifically for the Norton 500, so it belongs in a Norton engine rebuild, not a unit or pre-unit Triumph twin. We don't have much more detail on this one beyond the ring set designation and the oversize spec.
If you're piecing together a rebore job, give us a call and we'll confirm this is the right oversize and bore family for what you've got before you order.
