Despite all of its faults, a Norton Commando has the "right" looks, sound, and feel. Of my 10 or so bikes, it is probably my favorite. Unfortunately, it dates from the days when a motorcyclist would have to know how to do the maintenance and repairs himself. The British motorcycle industry catered to customers who they believed wanted "real" motorcycles that dripped oil, needed a kickstart and needed a lot of hands-on tinkering. "Real" bikers wouldn't ride Jap bikes. Yes, Ted Simon rode a Triumph around the world, but he was prepared for the inevitable breakdowns and was able to spend time getting the bike fixed (as well as time in jail, etc).
I bought mine from a fellow who did not want to ride a bike that needed regular work. He bought a Triumph Thruxton that captures the look of a classic British bike and with aftermarket pipes also has the right sound but built to a very high standard with low maintenance. I am less impressed with the Norton 961 so far. Since I don't depend on my Norton as my only means of transportation, I don't mind having it down for a few days at a time for repairs. Still, I ride it to work regularly. Compared to when the bikes were new, we can now call for help with cell phones and spare parts can arrive from suppliers in just a couple of days.
When I was a kid, my Triumph was my only vehicle for awhile. I kept boxes of spare parts and carried quarters for pay phones. Too many times, I would call a roommate to drive out to where I was broken down and to bring me a cable or a Zener diode or something I needed to get home. I still have a couple of shelves of spares that I have accumulated over the years.
I have also had new bikes that left me stranded with failed electronic ignition (Hinckley Triumph), failed regulator/stator (Harley) that are unfixable on the side of the road.
