I did the same thing several years ago. Snapped the shaft just above the threads at the clevis. I have some pictures if you'd like them. I managed to get it repaired under warranty through Ohlins USA (albeit being in Australia). Still cost me a few in return postage plus got caught in customs on the way back so had to pay some processing fees.
This was before I had the knowledge to work on them myself.
Did you come out of it OK? I was doing between 80-100km/hr when I dropped the back end in a pot hole. Thought it felt a bit harsh, then the next bump really hurt. Luckily the shaf locked into the outer edge of the clevis and held the back end up enough that the rear wheel could still turn or I'd have been cartwheeling.
I also know another bloke who's had a TTX shaft let go (different bike).. know him personally. What are the odds?
