Knowing  Hubert „Hatt“ Sommer is ways more than just knowing another manufacturer of additional bikeparts. It is a mixture of a unique biker , combined with real „good old school“ craftmansship, reliabilty as much as a person as with his products. Both build to last.


And Hatt is not just talking about quality – he is testing his products himself out on the road- and especially off the road. Customizing for all kinds of exhaustsystems (and panniers in the past) – proven quality for a lifetime. Put it on the GSA to enjoy the sound of silence ( that was pretty good before) and to save some 1,5 kgs, Not the most important in a GSA – but adding to the joy of riding
