Touring motorcycle searches in the US are about all-day pavement: Honda Gold Wing, Harley Road Glide / Street Glide, Indian Roadmaster, BMW K 1600 and RT, leftover Yamaha FJR and Kawasaki Concours on the used market. The job is wind, fuel range, and a passenger who still likes you at dinner.
Baggers are cruisers with luggage. Sport-tourers keep a higher peg and a fairing. Adventure-tourers (GS, Multistrada, Super Ténéré) do the same miles with more suspension and worse still air at 80 mph unless you add a tall screen.
Weight is the tax. A loaded Wing or bagger is 800–900 lb wet. Practice U-turns in an empty lot before a national-park parking lot. Shaft drive is the touring default; chains on a sport-tourer mean more lube stops.
Best touring motorcycle lists that ignore seat height and dealer maps are brochure copy. Sit on the bike with your boots and a passenger, then price used Wings against a new mid-size GT.
