 I'm guessing but it looks like this video was filmed in Australia. Two guys are standing with their motorcycles by the side of a large curve in the road with a third guy filming the curve with a video camera. A fourth guy on his motorcycle comes around the curve on the very outside but he leans to far over and goes sliding on his side through the dirt and off into the brush on the far side. The other guys rush over yelling "Are you okay Pete!?!" and they finally find him walking out of the brush. He is wearing pretty good protective gear and doesn't appear to be hurt badly if at all when he comes out of the brush.
Watch this guy make the slide of his life through the dirt when he wipes out on his bike in this video. Source: Big-boys.com |
