Ride what you want. I'm a flat six lover. Have a Valkyrie and my F6B. I've tried V-twins , but just love these flat 6 engines. That being said, I am 5'8" tall and personaly think the F6B/Goldwings seem to be built for people my height and maybe up to 6 ft. I can see where someone taller than say 6 ft might find these bikes lacking in leg room. For me, I think it's perfect. I also love the way this bike can go from cruising to getting after it in the twisties.
In the end, you got to do what you gatta do.
