The bike was smoking badly before he launched it, so I'd say it's clear the seizure caused the crash. Bad luck. It's like Pastrana -- half his crashes weren't his fault. JBS is not Pastrana -- he's way faster and has proven himself more than Travis ever did in the racing game -- but there are some similarities. It's win or crash with both of them. Bubba just wins more and crashes less than Pastrana. I hate it when he's not racing, though.
