Yes, that is what sucks about almost all metric motorcycle dealers. They won't let you take one for a test ride. HD dealerships on the other hand will fall all over themselves trying to get you on a test ride.
Go sit on a F6B. If the ergonomics feel right...you will be happy with the bike. There are other aftermarket options as well for the pegs, seat, windshield, etc so you'll never be "fixed" into a static OEM posture while on the bike.
