National Cycle’s VStream Windscreens were developped to complement Harley-Davidson’s newly redesigned FLTR Road Glide and their triple-vented shark nose fairing.
VStream’s cutting-edge aeroacoustic contour features a wider profile at the top, which pushes turbulent, noisy airflow to the side and away from the rider’s helmet. This extra width creates a quiet pocket of air with significantly reduced helmet buffeting for a calmer and quieter ride compared to the stock screen, they say.
VStream windscreens are made from tough 4.5mm Quantum hardcoated polycarbonate that makes the VStream 30x more scratch resistant than acrylic, and 10x more than standard hardcoated polycarbonate.
Made in the U.S.A., National Cycle’s windscreens are protected by a 3-year warranty against breakage. They are available in three configurations: the Low Windscreen with a Dark Tint (Part #N20433), the Touring Windscreen with a Light Tint (Part # N20432), and the Tall Touring Windscreen with No Tint (#N20431).
