This whole GoPro video, showing riders Ken Roczen and Ryan Villopoto duking it out for the lead at the 450SX Class Supercross race at the Georgia Dome earlier this week, is insane.

The video shows the whole race in alternating helmet cam views from both riders' perspectives. I highly recommend watching the whole thing, but if you want the goods, skip to 4:20 to watch the final lead change. Ryan Vilopoto takes too tight a turn in the 14th lap and loses a lot of speed. Ken Roczen passes him in the air on the next jump, and holds on for the final six laps. Total awesomeness. This is why the world needs GoPros.
