I take the screen off mine on occasion.....but I usually end up in a headwind and that is much harder to deal with without the windshield. I don't like the Rollie Free method of motorcycle control......
I'll still use a screen for long range touring though. I admit that while it is very enjoyable, riding all day with no screen at high speed was most fatiguing for the old fat man.
Oh and I got a solid 30 mpg, which I thought was pretty good for the way we were riding
For me, riding without the windshield is not an option. I rode the scoot au naturel for about 20 miles and silently vowed, never again. The severely myopic crowd, at least in my example, cant handle the specs bouncing and jostling around as the whole world does likewise. I like the look and the concept but I would be in a cage without the windshield option, and thats not an option I want to contemplate.
