I like it a lot. If he had a title and I had the cash I would have it. I think I would find some shorter handlebars but I doubt I would change much else. Not sure if those are stock or not but they look like mini apes to me and i am not a fan of that look.
FYI, it's likely going to be for sale again in the near future. The owner was a sport bike rider before this, and even though he really enjoys many aspects of the Wing, he really likes the riding position of a sport bike better.
