I don't ride a Norton myself, but I searched for a Commando motorcycle for a long time – I've since given up the search. With a bit of luck, I might be able to snag a pair of new, unused mufflers for the 961 Commando – currently on eBay. (Item number: 277603137636) I wanted to mount these mufflers on another motorcycle with a similar engine, but I've now been able to get suitable original mufflers.
The bike is a Kawasaki 750Twin... a german tester wrote a long time ago: "The best 750cc British bike ever built in Japan."
