I'm disappointed with the commuter screen. ... the thing changes a quiet, smooth, and pure ride to a ride full of pounding turbulence that gives me a headache and makes my ears ring after the ride.
While before you have an even spread of wind and weather all over your torso, the windscreen just pushes the wind, now faster and with more turbulence, onto your head, shoulders, under the helmet at the neckline, hands, and arms.
I'm with you on the buffeting. I've ridden well over a quarter million miles on primarily sport bikes, and I much prefer the smooth, even, steady & direct airflow over almost any faired bike, even larger touring bikes that come standard with a large windshield, presumably tested in wind-tunnels by guys with more research funds and resources than Mr. K & Mr. N have at their disposal.
That said, I've ordered the commuter screen for my dog and hope to angle it down low enough to protect her without sticking me behind the chaotic maelstrom behind the shield.
