OMG! Who taught that guy to ride?? Tell the guy on the red bike to take an MSF class or some sort of formal training before he kills himself! He's leaning the opposite way of the bike when turning and sticking out his outside knee! Not even mentioning the unnecessarily aggressive riding, but at least if you're going to ride stupid, do it right. I know I probably sound like a dick now, but that's probably the worst form/body position I've ever seen.
Seriously...strongly suggest an MSF class for that guy. The sort of riding he's doing is what you do on dirt bikes, except for this is all botched up on a street bike.
