According to my wife it does help quite a bit. The V-Stream is considerably wider than the stock windshield at the top which move the airflow out! However, I've also had my seat raised 1-1/2 inches taller than the stock "high seat", so I sit higher and in turn run my windshield higher which helps her. My wife rides her own F800-ST and is used to the wind associated with M/C riding. She thinks she in heaven on the GTL since she gets so much more protection than on her F800. She once told one of my local club wives (who drove a car to an event) to "find some gumption and ride with him or risk losing him to someone who will." Ouch! Well, I guess I'm just lucky that I have wife who loves riding (although she didn't start riding until she met me and was 55; ooowh, did I actually say that?). Good luck to everyone who has a temperamental pillion rider. I found a good one and I'm not giving her up.
