National Cycle V-Stream Windshield Dark Tint 10 For Suzuki M109R

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 Windshields will scratch and craze from debris, the environment, UV and daily wear. National Cycle made an improvement in the surface characteristics of windshields exposed to years of wear. Staring off with a polycarbonate sheet, the windshield's scratch resistance and optical clarity is enhanced by National Cycle's exclusive Quantum hard-coating, defining a new state-of-the-art standard. 30x more scratch resistance than typical acrylic windshields is saying a lot! Think of it as 30x more miles per windshield. Even compared to FMR coated polycarbonate, Quantum has 10x better scratch resistance. That's the kind of performance and strength you need from a motorcycle windshield. Think about riding into the sun or at night and not having to look through the glare of fine scratches that eventually show up on your screen. Quantum coating gives your windshield much better optical definition and clarity, and your windshield will stay that way a lot longer. Developed for windshield use by National Cycle, Quantum coating takes motorcycle windshields a quantum leap forward in abrasion resistance and outdoor life. National Cycle applies this crystal-clear hard coating to polycarbonate material.
