if neither can be avoided. The lowsider has the advantage of the motorcycle sliding before the rider, thus not threatening to crush them. Also, a lowsider tends to send the rider sliding across the road whereas a highsider is considered more severe as it violently throws the rider from the motorcycle

Lowsider crashes are not usually caused by braking in a straight line in dry conditions. It is more likely that the rider will go over the handlebars through too much front wheel brake force or will lock the rear wheel resulting in a straight skid. The name derives from the fact that it is the low
