Just mounted a Givi D1136ST screen on my PCX and went for a test ride, i was expecting less windforce on my chest and less noise around my helmet but during the ride i noticed wind turbulance some 55" behind the screen, just in front of my chest

The wind noise around my helmet was more of a steady flow rather than the erratic flow before when i had the stock screen mounted, i can't say anything about fuel economy yet, but it seems a bit better.
The positive thing is that i have some more rain and debris protection, anyone else with the same experience?
Cheers, Ronald.
