I'm going to go out on a limb and say that the audio was left out on purpose until the State LEO cuts him off. I'm willing to bet there were sirens blaring behind the biker the whole time which is why he looked back. I don't think he looked back because he was stopping, as others have said, because there didn't seem to be any visable reason for him to stop right at the time he looked back.
This seems like nothing more to me than an idiot trying to set up the police department for public ridicule. Committing an illegal act for the purpose of making an LEO look bad is hardly an example of good citizenship.
