I have the adapter mounted on a fairly new KTM bike that a - in my opinion - has standard luggage rack at the factory. Unfortunately it was not possible to assemble the adapter, since the screws in the rear area for attachment were too short; Parts of the hinged spring part of my luggage carrier ware in the way. Only after I had (unfortunately only possible with some violence) removes the arm of the luggage rack, I could see the Rixen Kaul and mount adapter 208. However, there is no turning back: The spring arm is broken during disassembly. Otherwise, the adapter works - once it has been successfully installed - very well his destiny!
