The first factory bike to blow up at this years Dakar?
A Yamaha.
"Contaminated fuel"
But hey, its clutch was still intact.

Bit of a misguided comment. No bike can run on water and when they put clean fuel in back at the bivouac it started and ran fine.
Don't go and spoil a good story with facts 
Yes, it is obvious that the contaminant in the fuel damaged that engine.
But like Altie said, the clutch were fine, supertough those Jap clutches.
