We all witnessed what a rough day Ken Roczen had last weekend in Atlanta. First he crashed hard in practice and injured his foot, and then he crashed again in the main event while coming from behind. All we saw of that second crash was Roczen and his RCH Suzuki flying through the air and landing hard on the side of the track. Well, thanks to GoPro we get to see exactly what happened to him. So sit back and ride along with Ken Roczen and the GoPro Hero4.
