Having gone through 70,000 trouble free kilometers on the bike, I had said to the wife what a great machine it's been, no problems blah blah. So, then the wiring craps out and I had to replace the cabling connection to the bottom of the ignition switch. Once that's done, a couple of days later I'm enjoying the GS again, but notice a slight vibration...on the right footpeg. Hmm, so, thinking no more of it (as I'd been using the CX for a couple of weeks, so thought it was just something I hadn't got used to). Go to overtake a car on a fast A-road, and hear this clunking noise, so, had to abort the overtake and pull into the side of the road, just as I'm slowing, the clank gets horrendous and the back wheel locks up.
Had it trailered off by the rescue service to BMW Cannes, and it turned out to be a broken shaft. Had a look round here, but it doesn't seem a common problem. What strikes me is the amount of damage. This bike has been regularly serviced by BMW, so I would expect it to suffer two potentially very dangerous problems like this, and it's putting me off the bike now..
The wiring problem left me stranded in the middle of the road with the bike completely dead. The shaft problem could have been far worse if it had happened on the Gourdon road I'd just come down...

Funny how you never look through the technical pages until you have a problem. Which is what I did, and found out I should have cut the cable ties off
. Really bizarre break of the shaft though. I hadn't noticed any crunching or grinding noises until the vibration a few minutes before it failed. Guy in the garage said he's never seen one like it on a GS. As has been pointed out, looks like it had got very, very hot...Unless that was the French BMW mechanics cutting it apart with a blow torch. I'm still gonna write to BMW France, and kick up stink. The wiring fault should be known to BMW by now, and picked up in the regular servicing. The shaft failure is just weird...
