The Hall Sensors are what creates the spark for the ignition and these do occasionally die. This is normally fixed by replacing the complete ignition trigger unit at horrendous costs but the Hall Sensors can actually be replaced at a minimum cost. Replacement does require mechanical ability and soldering skills. For the Airheads a strip of the trigger unit is required, the new sensors must be riveted in place and the wires trimmed and soldered. For the K Series and R11 Series the unit must be detached, the new sensors riveted and the wires trimmed and soldered.

These sensors fit all Airheads with electronic ignition, all K100's, K1100's, R1100's & R1150's. They may well fit other models too but I am uncertain.

BMW Classic pannier keys. Two different Sudhaus keys were used for the early Classic panniers, one for the top locks and one or the frame catch. Very difficult to find. These keys are used and limited numbers.

The later Touring panniers used a different key system with a three digit number such as 054, 047 etc. These keys are impossible to find new and I have a very limited selection of the following used keys:

Key 040  One available

Key 044  Two available

Key 046  One available

Key 047  Three available

Key 050  One available

Key 054  Six available
