Makes me what to run out and install one today. Never understood the concept myself. Motorcycles are Motorcycles. You want comfort from the wind and a place to hold your cup then drive. If you want the wind biting your #ss and the emotional high from riding then get on your bike and ride. Windshield not required.
Just to show how stupid/relaxed the motorcycle test is in the States(most States) the lovely lady who brought the scooter to class can use it all weekend and if she successfully completes the course she can then go and buy a Hyabuse without even learning how to use a clutch or shift gears.
I've been on both sides of this fence. Ate a lot of gnats and been whacked in the face by a few large hard shelled flying beetles. Two days ago a rock hit my windshield and it could have hit me point blank. FORTUNATELY, my windshield is electrically operated and goes up like a force field at speed and down for air when I want it. Power windows really pisses the Harley Queens off in their $35k chrome carriers. I'm already ugly Dave. Having an eye put out or a dent in my forehead wouldn't help me at the nursing home.
