I just purchased a very nice 2007 650 Burgman from a retired dentist who had no clue to what he had. He had put less then 200 miles on it in the two years he had owned it. When I was looking at it I asked, how does it shift through the different gears and he had no idea what I was talking about. His answer was, " it's automatic, you don't shift it ". I preceded to show him the buttons on the left handlebar and he had no clue what they were for, or how they worked. I was nice about it and when I took a ride all worked as it should, so I let it rest. I guess he never read the manual either. Well, when you get to the end of your ridding days, I guess these thing happen.
