When I had my Harley Softail Deuce, I wouldn't dream of putting a windshield on it. It wasn't cool in my book. As a result, I probably never rode it over 60mph. I've had 3 scooters since then. They all have windshields, and I love that. My People 150 peaked out about 55, but the 2 300cc's since then let me cruise comfortably at 70+ if desired. If I tried a windshield on my Harley, I may still be riding it. The Puig 6790H windshield I have now is perfect. My line of sight is just over the top of it, so rain and dark aren't a problem. If I have to, I just slouch down a little, and I'm out of any wind.
