Our 1200C windshield has a larger sweet spot than the stock OEM touring sizes, reducing back pressure and wind noise by incorporating a NACA style aerospace vent in the front of the windshield, just above the headlight cutout. The BMW Standard Touring dimensions are 22" height and 19" width (when measured across the top bolt holes). The windshield is available is varying heights and widths to accommodate almost every rider size. The windshield is also available in blue, green and light gray tints, and in clear. All shields are manufactured from aircraft grade acrylic in .187 thickness. All edges are hand polished to a luster for a great look. Windshields will fit on the stock BMW mounting hardware.
