I don't know that any windscreen is more efficient than just the rider. Unless you're ducking in the little bubble of a sport bike, I don't think they add any aero improvement and are entirely for comfort purposes.

I had a cracked windscreen completely break away at full throttle on the CB750, and I want to say I gained another 10 MPH of top speed after that. It was making that big of a difference in drag.
