The windshield of the R1200GS "shakes" quite strongly, especially at low revolutions and on fast trips. Sometimes it shakes so strongly that real turbulence occurs and the in no way bad wind protection of the R1200GS decreases significantly. Even using the small hard part windshield aluminum parts (01-044-0380-0) is of relatively little use in this special case because the forces simply act further up. With this support the windshield is supported at more places and the problem is almost eliminated. It is very easy and quick to fit.
