I installed my Cal-Sci tinted shorty and like the result. I'm 6' and keep the seat in the low position. Screen position 1/2 so far.
Wind hits the helmet at the nosecone at low speed 30-40 mph, bugs can woft over the screen and hit your neck below 30 but the added ventilation when it's hot and humid is welcome.
At higher speeds wind flow moves up slightly, the roar seems less and following SUV's and pick-ups (Texas) produces less helmet wobbling.
At highway speeds (60-80 mph) in traffic with large trucks and associated turbulence this is a different bike, the shake and wobble I assumed was coming from the handguard wings and wacky fairing shape is greatly reduced. Clean air lets the helmet do it's thing for better or worse.
It is much quieter and seems stable at 90+ but I need a longer ride to confirm.
It is shorter, wider and not optically perfect when viewed at an angle, a non issue for me. I have no rain experience yet but assume my lower helmet area will get more water than the stock screen.
Well packaged, tire guage, micro-fiber cloth and cleaner included. Happy so far and what I expected, a long tour next week will be the true test.
