No matter what box is checked on a specification sheet, a modern motorcycle wins over an old one (huge h.p., electric starter, fuel injection, disc brakes, plush suspension, reliability, …). However, the same is true for the specifications of a BMW, Ducati, Honda, Yamaha, etc. compared with a Harley-Davidson yet, in the category of large motorcycles, Harley sells twice as many annually as its largest competitor. So, clearly technical specifications aren't the only factor involved with decisions of which motorcycles to buy and ride.I have often considered buying a modern bike but I think it would be too nice and easy to ride and I would end up being idle and leaving the others in the garage.
A friend will be arriving from Dublin in a few days to ride motorcycles around the Southwest for a week. Based on technical specifications, we should be on my modern Ducatis. But, we'll be on my old Gold Stars. Although the "non-technical" reasons for such choices are understandable, they fill an hour-long lecture on "The Art and Science of the Motorcycle," so would take too many words (and images) to describe here.
