I understand how you feel. I like a full windshield and I like no windshield. I was thinking along the same lines as you............have a quickly removable windshield for when you want to ride in the open air. Now, you may be different, but my only complaint, when I ride at speed with apes, was the wind blast on my chest. My complaint, when riding with a full shield, was that I didn't care for the look and I could not have my bars in the forward position that I wanted, because of the shield. As mention above, a bar mounted shield would have filled the bill. I really didn't want something removable, because I sometimes ride 100 miles of freeway to get to a place that I want to ride without a windshield...........that was my problem. I compromised and just went to a short shield. I don't know the dimensions, but you can see it on my avatar pic. It keeps the wind off my chest at freeway speed, but still gives me the open air that I like. The best thing is that it stays on the bike, doesn't look at that bad and it works for me.
