Knowing how likely it is that news coverage is incomplete and innaccurate, I would reserve final judgment on the causes of this event.

The information on hand supports speculation that the individual did not equip his motorcycle with gear and supplies to enhance chances for desert survival in case of misadventure. We can also speculate that he did not do as Chris suggests: set up caches in the area of operation to enhance chances for survival in case of misadventure in an environment known to be unforgiving toward man and his machinery.

Other speculation would wonder if tempting fate was the all too successful goal.

In any event, I wish his spirit peace.
