Many complain that this doesn't do its job. After riding with this windshield for 6000 miles, I can say that it does reduce the force of the air on the rider, but it can never fully eliminate that effect. Riding position will also affect how well this windshield works too. If you have a sport bike that has you leaning forward, it'll do fine. If you ride an FZ1 like myself, it helps keep the wind from blowing you around a bit.
