Morgan Hill, CA –– National Cycle’s VStream is revolutionizing motorcycle windshield performance! While other manufacturers offer taller screens or air spoiler tops, National Cycle designed, for the first time ever, a windshield with airflow calculated and adjusted to quiet and comfort the rider’s environment.

The typical airflow pattern of the wake from most windshields is called a van Karman vortex. At speeds of 50-90 mph, the air swirls off the windshield in an approximate 90-degree segment of rotation, hits the bottom of the rider’s neck on the way up, and curves off the shoulder at approximately 45 degrees. We gave the VStream its name for the shape it takes at the upper edge. The patented “V” shape is so quiet because it pushes this vortex out and away from the side of the rider’s head. The rider’s helmet then resides in still air, and the passenger’s environment is greatly improved as well. Of course, with small sporty screens of different sizes, the effect on the rider will vary, but there is always a notable difference in quietness and comfort!

VStream windshields deliver unprecedented durability and optical clarity through the use of 4.5-6.0mm thick Lexan® polycarbonate with FMR hardcoating or our exclusive Quantum™ hardcoating.
