National Cycle V-Stream FMR Windshield Clear For Yamaha FZ1 06-10

National Cycle revolutionized windscreen performance with their new VStream windshields. They are well known not only for superior wind-deflecting comfort, but also for a riding environment that is calm and quiet. In order to create a more comfortable ride, other manufacturers offer extra-tall windshields or spoiler tops to try to lift the air stream. But National Cycle designed, for the first time ever, a windshield with contours calculated and adjusted to manage the riding environment. The airflow pattern of the wake from most windshields is call a van Karman vortex. At speeds of 50-90 mph, the air swirls off the windshield in an approximate 90 degree rotation vortex. It then hits the bottom of the rider's neck on the way up and curves off the shoulders at approximately 45 degrees. The VStream is named for its unique V shape. National Cycle's design is so outstandingly quiet because it pushes this vortex out and away more than four inches from the side of the rider's head. The rider then resides in an environment virtually free of irritating wind noise. The passenger's environment is greatly improved as well. The VStream's advanced V profile, unique three-dimensional contours and smooth radiused edges all contribute to cam and comfort in the riding environment. Unsettling wind turbulence is effectively pushed aside, and this fatigue-reducing experience is greatly appreciated by the rider and passenger. The VStream is the most comfortable windshield you can ride behind.
