When I first mounted the Viper windshield on my Yamaha Virago it was obvious that the designer had not taken that bike into consideration. I did finally get it mounted and a test ride around the neighborhood led me to believe it would work well. My first ride at highway speeds with gusting winds proved me wrong and when the windshield shifted it scratched a corner so I can't return it. I have come to the conclusion that it is too much windshield for a two point mounting system and so I need to figure out a way to add bottom mounts. Very disappointing!
