Makes an incredible difference over the standard screen of course. Hard to judge speed at first, thought I was going 15mph slower. No helmet shake at indicated 80-85 on bridge where I'm always getting smacked around when doing 65. I was a little too warm in my leather jacket yesterday below 45mph (it was sunny, high 60's). Hands are out of the wind, including fingers when covering the levers. Riding with tractor-trailers is quite comfortable.
It is louder, or something is different, perhaps it is actually higher air pressures on the eardrum. Can hear the engine more. With earplugs there is no wind or noise fatigue to speak of. Where I earlier was approaching the borderline for hearing protection I feel the need for it now.
To me, it seems as if the noise is coming from behind, where the air is hitting now on rear of the helmet and my back with a little turbulence. Don't think helmets are designed to reduce noise from that direction, maybe should close rear helmet vents? Dropping my head 2-3 inches makes a huge difference, laying on the tank is downright peaceful. I intend to experiment with raking the angle back/letting more air in around the headlight in hopes of getting a little more pressure behind the windshield - to push the envelope back or lessen the pressure differential.
Seems to handle small bumps well. Rock steady at higher speeds as mentioned above.
Overall very satisfied, especially with winter on the way. Pros outweigh cons, and will do so even more in the cold. Thanks again to the OP.
