Hard to get too worked up, considering how many times over the past almost 120 years, people have said HD is done. And yet....
Same was said about many car Manufacture, like Oldsmobile, Pontiac, Mercury and so on.
I do not think HD will go away, but they will continue to have less and less sales. Yes there are younger people in late 20's and early 30's being the, but not near enough to replace the HD loyalists that are dying or giving up riding.
The Harley touring line is the Most expensive motorcycle out there, yet the others have a much more modern frame design, suspension design, better power, better handling, Ride modes, and the list goes on. Only categories Harley wins in are Looks and options for customization.
Hopefully, Harley does more with the Pan America motor. That bike is a step in to a new market, and is very advanced. ADV bike of the year, here in USA and in Japan and a few other countries.
Harley really needs to update the touring line bad.
