BMW positions the S1000 XR as a cross between a sport, adventure and touring bike. The Wunderlich Marathon Windscreen delivers additional comfort. A great deal of thought went into the design of this screen and the shape was perfected through extensive testing. The result is a windscreen that offers outstanding wind and weather protection. The strategically placed opening allows just the right amount of air flow through the lower part of the screen to eliminate negative pressure and resulting turbulence. This windscreen is the result of extensive testing and it provides exceptional wind protection while retaining the sporty look of the XR. Intense road and complex wind tunnel testing have confirmed the outstanding effectiveness of both the sport and touring windscreens.
