On a unfaired bike like the GS, even a well designed windscreen provides, at best, just minimal protection for a driver and passenger. That's why we design 2-Piece Fairings for the GS's.
Notification: The R1150GS 2-Piece Fairing requires our custom made brackets which are no longer available due to high production costs.
You can not mount the system without our brackets. Replacement plastic pieces are available for those that already have the R1150GS brackets.
