Looks to me like that short shield is really for styling purposes. The HD Road Glide has that kind of windshield, as does the Kawasaki Vaquero. While I like the F6B, generally, I don't like the windshield. Might be great for those who like the wind in the face thing, but not me--I prefer keeping it off my face, along with all those bugs!!
I wonder if some of the weight reduction was done by eliminating the centerstand and reverse? I rather suspect that not putting a trunk on it accounts for about 25 pounds or more of weight. It ought to be a pretty good handler without the weight of the trunk up high.
