I thought, "I need a screen to increase endurance".
Well heck yeah man. But you know, it seems that riding sans screen just means a different configuration: Full face helmet with a decent jacket when rolling along at 5500+rpms.
Riding back from Bryan TX, Cinnamon Girl had a summer screen. The word Frisbee kept coming to mind... The buffeting was so bad that I rode with my face hanging to the left and right a lot. A steady breeze, albeit intense at times, is so much more desirable than those little tornados.
Saying that having a screen when it rains makes a difference is so simple. Well it doesn't. Think about it. Wet is wet. Don't we slow down when it rains anyway? Riding properly attired, again, is so important that it cannot be stressed enough. Getting by with shorts and flip flops is fine. Do it. But then we have a problem with the elements and so goes the desire for a windscreen. How can one truly ride in the wind when wearing a fullface helmet? Throw a leg over and twist the throttle, that’s how. I wonder the level of Joy of that guy I passed on the beltway around Little Rock who was not wearing a helmet and had no shield as the rain was pounding us? He looked like he was having loads of fun while he was looking cool. Looks blow. Being comfortable is being in that proverbial Great pumpkin patch. For you Freudians, "Happy Place" For me it was wearing a rain suit and wishing someone would turn on the AC.
So what am I rambling on about? Why it was the egg that came first rather than the chicken. And you can bet that the egg had no need for a windscreen.
Enjoy your sickle. Ride it naked

, ride it with full armor

, but ride it.
Riding is what motorsickles are all about.
