I have the Faco midsized windshield. I am 5'8", if I rest my hands on the bars I am fine, but if I sit up straight I get wind in the eyes at 40+mph.
I made a
Mojave Full Moon Ride -- 150+ miles on the freeways, 60 miles through the Park, 30 down CA62 back to the freeway, and 100+ miles back home. On the Scoot was the third. First was on the Savage with a Flyscreen, and the
second with a Street Shield.
The test is on I-10 going back west to L.A. in the early morning. 60 mph plus a 30 mph headwind is... ah...
fun. On the Savage with the Flyscreen I had to lay on tank, not fun at all. On the Street Shield I was totally comfortable. On the Vespa, down CA-62 the windshield was useless due to the 30 mph sidewind. Hanging a right onto the Interstate the Vespa was totally comfortable, altho' not quite as fast as the Savage.
Unlike the Street Screen, the Faco Midsize Windscreen covers my hands. On the Savage my hands went numb with temperatures below 58 degrees. On the Vespa I am good down to 50 degrees
