I've had the Givi screen on my last 3 scooters and it is great.
But the OEM on highest setting is great. Only my hands exposed. But for only about 3 or 4 months a year it is cold here.
I'm thinking I like how the OEM design eliminates the back pressure and the wind stream goes over my head. No buffeting.
Since I wear OF helmet and glasses, buffeting can make for some interesting vision effects.
I do like the wings of the Givi deflecting off the hands. Being old and arthritic makes one consider accessories that aren't to ones preferred desires.
Considering some good hand guards but not sure about fitting them with the bars covered. Was hoping someone else would experiment on that as I've experimented in other areas....
