National Cycle revolutionizes windscreen performance with its new VStream Windshield. To create an unprecedented experience for the sport touring rider, VStream introduced QUIET into the riding equation.
To create COMFORT, other manufacturers will offer taller windshields and spoiler tops to lift the air stream. But National Cycle designed, for the first time ever, a windshield with airflow calculated and adjusted to quiet and
comfort the rider's environment. In addition, VStream windshields are designed with an unprecedented area of protection and an outstanding level of STRENGTH and OPTICAL CLARITY that is only available through the use of FMR hardcoated Lexan polycarbonate and our exclusive Quantum hardcoated Lexan polycarbonate.
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, i.e. it rolls off the windshield, 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 "V" shape 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's helmet then resides in still air, and the passenger's environment is greatly improved as well.
The advanced, patent pending "V" profile and three-dimensional contour of all VStream windshields creates a calm and quiet air pocket for the rider. This improvement is notable for the passenger as well. More riding comfort means more miles in the saddle without undue fatigue at the end of the day. The VStream is, without a doubt, the most comfortable windshield you can ride behind.
Every aspect of finishing a shield will contribute to its level of strength. That's why our VStream windshields are constructed from 4.5-6.0mm thick Lexan polycarbonate. National Cycle was the first company to use Lexan polycarbonate for motorcycle windshields, and nothing beats it! Polycarbonate has more than 4X greater crack resistance than High Impact "Aircraft" Acrylic, and 10X more impact resistance! That's STRENGTH!
Every motorcycle windshield has good optical clarity when it's brand new. But over the course of several seasons of riding, fine scratches, abrasions and hazing appear on your windshield, obscuring your view of the road. National Cycle's VStream windshields are specially treated with FMR hardcoating (3X more abrasion resistance than acrylic) or our exclusive Quantum hardcoating (30X more abrasion resistance than acrylic) to drastically reduce this common problem. So no matter how far you ride, you can count on National Cycle's VStream windshields to give you a clear view of the road ahead.
