Cee Bailey's Aircraft Plastics has a vastly improved windshield hold down knob for all R1200GS bikes. Our new rosette knob is longer, has a larger diameter knob, which is easier on the hand to adjust, and has an extended "shelf", which also makes it easier to tighten or loosen even with your gloves on. The best part is that our knob is designed to last a life-time; it has a full threaded metal insert, unlike the OEM knob which has a threaded screw that is pressed into plastic, and is also prone to breakage when being tightened. Not so with our design! Our Knob will take all the torque your hand can muster, and adjusting the screen on the "fly" just became a whole lot easier and worry free.
