Cal Crutchlow's lowside put him out of the points and Valentino Rossi didn't trust his Ducati not to crash so trundled around at the back (of the real bikes). Ben Spies Yamaha engine blew up before he could crash in the race but he did manage to highside during qualifying.
It may have been one of the most boring races in MotoGP history but there were no shortage of crashes. Bike riders are the bravest of them all.
