I'd like to say that a dealership in central Ohio SHOULD sell primarily cruisers while dealerships near mountain roads SHOULD sell primarily sporty and adventure bikes. In my way of thinking, you'd sell based on the availability of riding in your home area. Alas, I don't think that's the case.
As by brother-in-law has often said, sport touring is more a state of mind than a style of bike. The uptick of ADV bikes used for that purpose, virtually never seeing an unpaved road, certainly bears that out. Even a cruiser (think Honda CTXxxxx) can be ridden in an enthusiastic, ie sport touring, manner within the limitations of the particular model.
With all of that being said, I still find it a more comfortable seating position, and one giving me the impression of more control, to have my feet more underneath me than out in front.
The MSTA has certainly shown an acceptance for ADV, standard, and sport bikes being ridden in a sport touring manner. I hope we can add cruisers to that as well.
