RING SET 850 NORTON 060 - Hepolite NOS
Hepolite NOS piston ring set for the Norton 850 Commando, .060 oversize.
This is a piston ring set for the Norton 850 Commando, built to the .060 oversize bore. It's a Hepolite-made set, old factory stock rather than a new-production reproduction. Ring sets like this go in with a rebore, matched to pistons already cut to the same oversize, so this one is meant for a cylinder that's been bored out .060 over standard.

This is a Norton part, not a Triumph part, despite where it may show up in a mixed parts listing. The JRC-style part number and the 19342/060 alias both point back to the same physical ring set for the 850 Commando engine.
Being NOS stock, quantities are limited and it won't be a running production item, so if you're planning a rebuild around this set, it's worth confirming what's actually in the box before you commit a bottom end to it.
