From a Norton Commando owner
Oh yeah, there’s lots more...
I owned a 750 Commando back in 1977. Probably the funnest bike I ever owned. I got so used to the reversed shifter,brake pedal, etc. that I had a hard time getting used to the Honda I bought as a replacement.
I still wish I had never sold that Norton.
