if your talking about the spot at around 0:55, it honestly looks like the back end broke a little loose by the way the steering wheel turns so quickly and the angle the car goes to.
yeah, that's the part i was referring to.
look at the bikes in reference to each other. the yellow bike is inline with the front bike going into the curve and then cuts across to pull around his buddy.
it does look like there was some vigorous steering input around the same time from the porsche, too.
