As the owner of a 2 wheeled Goldwing, I have to agree about Goldwing trikes. Not much uglier than one of those. And to me they would be dangerous, I'd probably flip one in the first corner.
Having ridden a Burg 650 around a parking lot, they feel a lot like a Goldwing to me. I am reaching the point where a Goldawing is a bit much for me around town and in parking lots, but I have decided to go with a smaller motorcycle rather than a maxi scooter, and keep my small (125-150cc) scooters.
