I've owned a bunch of bikes, but I have never had a problem like I have had with my 2016 F7 when it came to finding a windshield that I would be happy with. Stock: Seriously? California Scientific: noisy. Givi AirFlow: noisy and buffeting at 55+. Finally, Madstad: no buffeting, still a bit noisy. On a whim, I fabricated two winglets and bolted them to the Madstad cowling. (see pics) Much less noise, no buffeting, and an adjustable screen for warmer days to boot. The winglets aren't gorgeous, but for five bucks worth of Lexan, two pieces of scrap aluminum, four bolts, and a bit of elbow grease, I can live with aesthetic issue!
