National Cycle's VStream® Windscreens have turned the two-wheeled 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 sport-touring windscreen that WORKS... look no further than National Cycle's VStream!
VStream Windscreens are measured vertically from the bottom center edge to the top of the screen, and horizontally across the back at the widest point.
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.
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.
Reduced wind noise... less turbulence... superior strength... perfect style. The VStream revolution is here!
Most VStream® Windscreens are a direct replacement for the OEM screen and reuse the same mounting screws, washers and nuts. If the mounting hardware can be improved, we supply that hardware with the windscreen.
All VStream® Windscreens are made from thick, durable polycarbonate with National Cycle's exclusive Quantum® hardcoating or FMR hardcoating. These are the best quality windscreens you can get, with excellent optical clarity, unbeatable strength and unsurpassed scratch resistance.
Our windscreens are dimensionally molded rather than flat formed for peak performance and a perfect, customized fit. All edges are routed and mount holes are precision drilled. You won't find a better windscreen than this!
All National Cycle polycarbonate windshields are covered by our 3-Year Warranty against breakage!
