I have changed windshield to Ermax high protection and color light black. I don't have problem with the standard screen but this looks much nicer, both design and color. It's around 40 mm shorter than standard screen. Personally I'm 1.83 centimeters tall.
It doens't make a huge difference compare to standard, perhaps less turbulence in normal speed. At higher speed there is still wind noise. I doubt you can eleminate that totally with any windscreen so who cares. Drive a car if you don't like wind.
Full turning circle works.
My last mod is more comfortable seat. Still looking.
