I've now fitted my Givi airflow screen, and I am highly delighted with the results. It took me minutes to change, then it was test time. I tried it at its lowest, which was good, then at its highest which wasn't so good. I now have it set so that I am just looking over the top, and I have now done in the region of 300+ miles, and not one of them had my visor down. I wear glasses, which is bad enough, but looking through glasses then helmet visor, was taking its toll. Now that I can have my visor up, its brilliant, and would highly recommend it to anyone. Thank you for this post, it helped me greatly.
