MadStad's patented mounting system allows riders to adjust the height and angle of their motorcycle windshield resulting in much smoother airflow, better wind protection and a more comfortable ride than any fixed windshield can provide. The complete system is custom-made for your bike and includes everything needed to mount and position the shield. Your bike will not require any modification. You can adjust the shield for the optimum height, angle and airflow for your height and riding position. While the MadStad windshield systems are fully adjustable, we recommend starting with the appropriate shield size relative to rider height. Kit contains: A set of MadStad adjustable brackets, The acrylic windshield, and all necessary hardware Windshields are made from 3/16" (4.5 mm) thick cast acrylic
