I was in my early 60’s when I sold my last two old British bikes. They were fine for the odd rockers run to the coast and regular Sunday runs with like minded souls, but I didn’t really enjoy the constant tinkering and jumble searches for parts. Regular visits to either the magneto man or the chronometric clock guy, used to empty my pockets quite regularly. I know a lot of people who really enjoy that side of ownership, but I really like to ride bikes, and so, as you mentioned, Japanese is the way to go, for reliability in the main, as well as a good turn of speed. Parts might be getting a bit more elusive, but there’s usually a way of solving problems. I missed out on early Japanese super bikes as children got in the way of that, but have certainly appreciated them.
