I rode most of my life without a windshield, but when I bought my Indian it had a windshield on it that I swore I would tear off the second I got home.
But then I realized that after an hour plus ride my eyes had not watered once, my ears weren't having ghost ringing, and my arms were just not tired....
When I picked up this bobber I knew I would want a windshield. I have been riding it for a month or two without a shield now, and I have to wear earplugs so that the wind noise doesn't make my tiniitus go nuts. Today was the first real ride with the screen on. And holy cow. I love this bike even more now.
Details: It is a madstad 20inch touring screen made for a triumph speedmaster. I modified it to fit the bobber by drilling some new holes, but otherwise I used the hardware and fasteners that came in the kit.
I can post some pics of the fitment if there is interest.
