Now on my 3rd week with Givi 266AF. Hot rides, cross winds, even rain, are completely different with the Givi. I did not use a book, it was worth the kick in the pants. It made a scooter that I liked into the best 2 wheeled ride I can imagine. Run don't walk. Kiwi Dave has the best price and I had the new windshield installed in less than a week from ordering.
