I tried a Givi airflow two piece screen on recommendation for my 2021 650 and couldn't stop my helmet being buffeted and shook over 60mph, it was fine slower, for over a month I tried it in every position and shimmed it everyway on the frame to no avail, worst screen I've ever had and the outer screen is soft and scratches very easily. In the end I bought a Puig, shimmed the bottom out around 5mm and it is absolutely perfect for me, I can see over it on to the road around 25ft in front, It gives quiet, calm. air, and can ride with my visor up at any speed, I am 6'-4",, what suits one doesn't suit another,
