I’ve noticed that if you see a Harley it’s being driven by an older man. I suspect that the demographic Harley appeals to is aging out. To move their market into a younger demographic they probably hired some marketing people, who are of course college graduates. College graduates are by-and-large liberal and probably have as much understanding of the Harley brand as the young female VP at Bush who came up with the present debacle. College graduates see the world through a special liberalizing lens. This means they see a world populated by people like them. (Thus, the upcoming electric bike.)
...and all those motorcycles hit the used bike market when their owner is too infirm to ride, their widow doesn't want it, or their heirs already have motorcycles of their own or don't ride.
It doesn't help that Harley Davidson appealed to blue collar workers in industries that have either moved up or out of the United States.
