I always thought the air vents on my Scorpion were useless, they never seemed to flow any noticable air. This weekend, in my sidecar ride, I was amazed to fell a lot of nice cool air flowing through the top of the helmet (my first side ca ride, and I'm noticing helmet airflow..). I have the Roadster screen on my America and I guess it sure does cut down on the wind. Even though my line of sight is well above the windscreen, I get no flow thru the helmet vents. Might have to pop that shield off for the rest of the summer.
