OMG, I heard a Grizzly Bear.
That video reminds me of the first time my cousin upgraded from a Suzuki JR50 to a Honda SL70 four-stroke (if you can call it an upgrade.) There was this gravel road over-looking a gravel pit (there are a lot of gravel pits around here, it's really just a big gravel clearing with pig piles of rocks everywhere). Rather than just taking the road out of the gravel pit and going up from there, our dads decided in their infinite wisdom that we now had 70 and 80cc bikes (I just got my Yamaha GT80 two-stroke) we could just climb the hill up to the road. After some struggling with a device called a "clutch" which I'd only learned of four hours before, I managed to make it up the hill, which was maybe 1/5 as high as the one in the video there. Meanwhile, Mark is down there struggling with his bike, primarily because he'd just let off the throttle too early. Half an hour later, Mark makes it up, crying and saying the bike had no power.
Now, my uncle is the kind of guy who doesn't take bullshit lightly. He's been known to yell at fast-food employees if they take too long. So after half an hour of watching his son getting his ass handed to him my what seemed to him (and to all of us, now) as a very simple hill, he was pissed. Red faced, he got on the SL70 (with no helmet or anything, by the way) kicked that bitch over, revved it up a few times, then dumped the clutch and proceeded to carve circles into the road, keeping the front wheel virtually stationary at the center of the circle as the back end swung around and sprayed gravel on everyone and everything. Then he stopped spinning and shot up into the woods (which looked just like a smaller version of what this guy did) and then disappeared into the trees. We could just hear this massive farting sound as he roared about and tore things to pieces. Then he blasted out of the trees, front wheel in the air, landed in the center of his circle, locked the back wheel, laid a big skid, killing the bike and stopping two feet away from Mark. "What the fuck you you mean it ain't got no power?!"
Many people throughout history have done Figure-8's in ice or on dirt. But only Scott managed to create a Figure-Q with an old SL70. The giant letter Q laid carved deep into the gravel, and remained there for five years until eventually it eroded away.
