I had some leftover headlight tint from Vvivid. Installed it on the windshield. It's mostly clear, and has a rubbery vinyl feel to it. Should work well as a chip guard, and it looks ok.
Put the 20" on yesterday and rode around and to work today. HUGE difference. I can ride with my helmet shield up and catch no wind at 50+ mph. Actually forgot once that the face shield was up.
I installed the 20" All the way down and angled the same as the stock windshield and no helmet...
