Sorry I didn't read your thread properly....I saw Givi D5127S and thought 'AirFlow'
The screen is tinted but not as dark as it appears in the picture.
I try avoid riding at night but as I look over the screen it should not be a problem for me.
I still get wind noise but as I wear earplugs this is not a problem, but more importantly no buffeting. Depending on weather conditions I can often ride at UK legal speeds (up to 70mph/112km) with my visor up. I'm 5ft 11
