The BMW F850GS Windscreen V-stream Windshield ZTechnik Z2377 Dark Tint Sport Screen 2019 Up is an aggressive-looking adventure sport screen, and gives the F850GS/Adventure rider good wind protection without sacrificing the bike’s cutting edge appearance. Z-Technik’s hardcoated Polycarbonate windscreens are super strong – they are over 20x more resistant to scratches and cracks, and 200x more resistant to impacts than regular acrylic.
