It is possible for the original steering stop of the R1200 GS to shear off in for example a situation where the bike falls over. If this happens, the handlebar can smash into the tank covering, causing damage to the painted surface as well as the handlebar switch. This can lead to expensive repairs and a great deal of aggravation. The Wunderlich steering stop provides a strong, additional point of contact and takes the strain off of the original steering stop.
Here's how it works: The bumpers bolt onto the lower fork bridge pinch bolts and contact the Telelever just before the stock steering stop would make contact. This softens the blow and as the rubber bumper compresses, it becomes a solid stop for the forks. With this part installed, the steering stop will fare better than your pride in the event of a spill.
