Using Google Earth, I have estimated the radius of the turn where the accident happened to be around 440 feet.

In order to reach a lean angle of 45 degrees and start dragging hard parts and low-siding there, the bike had to have been travelling above 81 mph.

Vmax (in mph) = Square root [ 14.9 * turn radius (in feet)]

I don't think that anybody with some street-riding experience would enter that curve at more than 80 mph.
Again, I want to believe that the reason of this fatal accident was a mechanical problem.
What makes you rule out that he just ran wide? He could've been going faster than the speed limit and still under your estimated 81 mph to drag hard parts. IDK why, just seems more probable to me that this was rider error and not his bike suddenly crapping out.
