My observation of the video indicates an old axiom is again correct, "Motorcycles are not dangerous, but a faulty connection between the seat and handlebars can make them extremely dangerous." This guy continually rides the center line, oncoming traffic be damned, same for all left turns, blind curve or not, usually with his body and the upper portion of the bike well over the line. I've been watching people doing this for as long as I can remember, cars, motorcycles, or trucks and am annoyed each time I witness this particular brand of stupidity. If you suddenly encounter an oncoming vehicle in or nearly in your lane you're going to try to get to the right as quickly as possible. Why not be there in the first place? All of us have seen road racers hang off to the inside of turns. They have a damn good reason to, they're racing, riding to the limits of their bike's and their own abilities. By leaning into the turn their bikes can remain more upright and allow them to make the turn at maximum velocity. Doing this on the street appears to be a product of the imagination. In the case of this rider it was absolutely pointless as he never had the bike leaned over very far during the entire video. I assume the cause of the initial slip may well have been gravel on the tarmac. At any rate, the bike quickly righted itself and was therefore back in his control. However, during that brief instant when it was not in his control sheer panic took control of the situation. The left leg quickly extended itself without direction from a brain that was functioning. Then the bike left the right shoulder and was back on the asphalt where traction was readily available. Again there was no input from the fear frozen rider so the motorcycle continued in a straight line to the other side of the road onto a wide shoulder that still appeared to offer a chance of recovery. Because we lost sight of him in the dust we can only speculate the reason he was suddenly getting a taste of the dirt. I think that he suddenly found the front brake, locked up the tire and it immediately washed out and dumped him unceremoniously on his face.
Immediately after the bike was back in the rider's control it should have been turned very slightly to the left in the direction of the road and all would have been well. Any rider possessing a natural affinity for riding a motorcycle would have done this and been on his merry way. Then he had a second chance as the bike was once more back on the asphalt and crossing the road but the passenger, I do mean passenger as there was no one home to steer the bike, sat frozen in fear or panic, take your pick. A squid without this natural ability will not react properly or at all and turn this minor loss of traction into a disaster as this one did. I emphasize natural ability as those without it can take lessons, attend schools or generally absorb information from many sources yet remain incapable of applying the appropriate reflex action to avoid disaster when an emergency arises. From what I have seen of people either riding or driving over the years indicates that the vast majority of those who ride motorcycles and who drive cars do not have the ability to ride or drive their chosen mode of transport with the skill required to do so competently. This clown and many like him should not be riding motorcycles because by doing so, the motorcycles they're riding become very dangerous.
