Comfort, Optics and Strength. This model of National Cycle's widely acclaimed VStream® Windscreen will fit 2014 and later FLHT and FLHX Harley-Davidson® models. The patented "V" shape and advanced dimensional contours push the wind vortex away from the rider's head, resulting in a peaceful, quiet riding environment. The passenger's comfort is improved as well and stereo users will notice it's not necessary to turn up the volume as much! Polycarbonate is used for outstanding optics and impact strength 23 times better than acrylic. Then we add our exclusive Quantum® hardcoat for scratch resistance 10 times better than FMR coating and 30 times better than acrylic replacement screens. This is one tough windscreen! Reduced wind noise - less turbulence - superior strength - perfect style. The VStream revolution is here!
