Norton anyone???

You don't see that done to Commandos very often. Because of the frame on them, its not easy to do and also because it was never that kind of bike. Hopefully that was done a long time ago before it was a "frowned upon". I recall there was a company that rebuilt them to more modern high performance standards out there but Commandos in stock form are great. I had this '71 a while back. it had the Dunstall 810 kit and was a blast.
