Hi when i got my Ten it had a Givi tall screen on and was given the original screen as part of the deal.
I fitted the original screen and experianced buffeting at around 65 to 70 MPH I returned home and refitted the Givi tall screen and it was a little better but not much.
I have an AGV AX8 DUAL helmet and when i stood up on the pegs it was much calmer than riding behind either of the screens

What I am planning is to reduce the hieght of the orignal screen so I will still offer protection to the insrument panel and i am in clean air flow.
May question is has anyone attempted this, and at what height did you reduce the screen to .

I also tried higher/ taller screens...ended up reducing mine by about 2 inches. Measure and mark out carefully. ..use a new hacksaw blade. ...round off with a file. Steve
