BMW R1200GS Windshield Clear Ztechnik windscreen shield Small VStream 2013 & Up Z2420 ZTechnik ® revolutionizes windscreen performance. The advanced V-shape and dimensional contours of the VStream® windshields push the wake, typically referred to as the von Karman vortex, out and away more than 4 inches from the side of the rider's helmet. The rider then resides in a quiet and calm air pocket. This improvement is notable for the passenger as well. The Z2416 brings VStream wind management and touring performance to the new 2008 and later R1200GSA. Its unique profile allows for full-lock steering and mirror clearance. Factory rake adjustment is retained for a wide range of adjustment and individual comfort.Lexan polycarbonate not usual cheap weak perspex/acrylic!! these screens are bulletproof- see our video for proof!
