National Cycle’s VStream® Windscreens have turned the motorcycle windscreen world upside down – literally! The patented, unique inverted "V" profile creates a quiet and comfortable riding experience unequalled by any windscreen on the market. If you’re looking for a cruising/touring windscreen that WORKS… look no further than National Cycle’s VStream!
The typical airflow pattern of the wake from most windscreens is called a van Karman vortex. At speeds of 50-90 MPH, the air swirls off the windscreen 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. The VStream® gets its name for the shape I 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.
Reduce wind noise… less turbulence… superior strength… perfect style The VStream revolution is here!
