National Cycle revolutionizes windscreen performance with the V-Stream Windscreen! The patented "V" shape and advanced dimensional contours push the wind vortex away from the rider's head, resulting in a more, quiet riding environment. These windscreens come in 2.0mm Quantum hard coated polycarbonate, and come with replacement deflectors in 1.5mm Quantum hard coated polycarbonate that are taller and wider than the OEM components. Windscreens bolt straight onto the OEM windscreen mounts, offering the standard adjustment options. Shields are offered with either a plain edge or an E43R EU-compliant beaded edge. Quantum hard coated polycarbonate is the material of choice for serious motorcycle riders. It is ten times more abrasion resistant than FMR hard coated polycarbonate, and thirty times more than windscreens made from commonly used acrylic or "aircraft plastic”. This high quality material, along with state-of-the-art manufacturing techniques, provides outstanding clarity, impact strength and scratch resistance unmatched by any windscreen maker worldwide.
