Have been experimenting with windscreens since the CB is currently my main longer-distance bike. This is the best setup I've been able to come up with: keeps wind pressure off your torso, without creating any turbulence at helmet level. It's a Givi Airflow AF49. To prevent helmet buffeting, I had to slide the upper adjustable portion of the screen to its lowest position. I cut off the (unused) lower half of the sliding part of the shield for a cleaner appearance... otherwise it looks kind of odd with the sliding part all the way down. I still think the CBs looks their best without any windshield at all, but this setup has proved to be very functional for longer distance / higher speed rides.
