High siders and low siders are crashes that occur due to a loss of traction and cause the rider to detach from the motorcycle
If there is one sport where the effect of physics is felt most intensely, it has to be motorcycling. To the casual observer, motorcyclists are a bunch of fancy-looking Power Rangers putting their lives in the hands of two wheels. In truth, however, there is much more to motorcycles than that. Riding one is a fine balance of making friends with some forces of nature, while trying to dodge others. But what happens when something goes wrong?

Are motorcycle collisions the only type of accidents?
There is no stipulated way in which accidents occur. Motorcycle crashes are generally attributed to collisions, bad roads or veering off-course. However, accidents may happen even if none of the above conditions are present. Such accidents are mostly witnessed at the race track; but they can also occur on public roads if similar conditions prevail.
Commonly called low siders and high siders, both involve the rider detaching from the motorcycle as they are attempting to turn. The rider and the motorcycle often continue to move in their own trajectories, even after the crash, owing to the residual momentum.
A low sider happens when a bike slips out from under the rider while taking a corner due to a loss of traction at the wheels. This generally happens due to excessive leaning, but can also happen due to a loss of traction arising from aggressive braking or acceleration while the bike is banked into the corner.
Demonstrated below is a low sider in action, wherein the motorcycle slides out from under the rider.
Impact of a lowsider
Due to the excessive leaning, the bike can slide onto its body work from under the rider, taking its wheels completely off the road surface. The rider generally gets detached from the motorcycle and follows a similar path. Unless there are objects to crash into, low siders are primarily abrasive, due to the sliding, and do not result in major injuries. Sometimes, however, the rider may fail to detach from the motorcycle and get dragged along with it, further compounding potential injuries.
High siders generally result from a rider trying to correct a low sider by counter steering. A high sider happens when the rear wheel of a motorcycle momentarily slides out of its line behind the front wheel due to a loss of traction while turning the corner.
However, it quickly regains traction and falls back in line with the front wheel. The resultant momentum is quite violent and causes the bike and the rider to flip over on its longitudinal axis, often resulting in very severe crashes.
Demonstrated below is a high sider in action, causing the rider to get thrown off the bike.
Impact of a high sider
The impact of a high sider is directly proportional to its intensity. Since the bike regains its grip suddenly after a slide, the residual momentum is passed on to the rider, who may get thrown off. The riders usually get launched into a trajectory that throws them to one side or in front of the bike. This typically results in impact-related injuries, such as fractures and concussions. Though riders sometimes manage to hang on to the motorcycle stubbornly and even regain stability, such lucky cases are few and far between.
Both low siders and high siders are caused due to a lack of traction. While the former causes the bike to tip over in the inside of the corner, the latter can throw the bike haphazardly. While there is no sure way of correcting a low sider, a high sider can be corrected. However, it is a highly skilled maneuver that is fraught with extreme risk. It involves the rider holding the motorcycle at its existing lean angle and letting it slide, while detaching themselves from it. The resulting crash is a low sider and much less severe than the high sider they avoided.
Thus, the more reliable way to save oneself from these crashes is to prevent them. Low siders and high siders result from sliding, which occurs when the traction available to the tire is no longer sufficient to carry the momentum. Heavy braking or acceleration when in the turn, worn out tires, and a reduction in the contact made with the ground due to excessive leaning are the most common causes. Thus, these crashes can be prevented by eliminating these factors.
Which is more dangerous?
It is now known to us that the primary cause of high siders and low siders are a loss of traction. However, in similar conditions, such as on a race track, a high sider is much more dangerous, as its launches the rider into an uncontrolled trajectory that can intersect with that of the bike.
That said, the occurrence of these accidents is not restricted to the race track. When on public roads with fellow motorists and obstacles to crash into, even a low sider can be extremely dangerous.
Occurrence in other vehicles
High sider and low sider crashes are not restricted to motorcycles. They are also observed in other single-track vehicles, such as bicycles, and those incidents have similar dynamics as in motorcycles.
As we now know, the occurrence of high siders and low siders is more about skill than external factors. Since these crashes are not only limited to race tracks, they can be quite fatal if they happen on public roads.
The riders, on their part, must seek to up-skill themselves while investing in high-quality motorcycle gear that will mitigate the impact of such crashes. At the same time, they must ensure that their tires are in optimum shape so that maximum traction is available to them during the course of their ride.
