On sait qu'il est difficile de diriger les motocy-  We know that it is difficult to steer motorcycles.

alors qu' aux allures rapides la conduite est difficile.  while driving fast is difficult.

En effet, aux grandes vitesses, on constate des gauchissements  Indeed, at high speeds, there is warping

convénient d'imposer un choix-ou bien une solution intermédiaire qui ne permet pas, d'une manière simple et aisée d'adapter immédiatement le motocycle aux conditions du moment, et même éventuellement de l'adapter pendant la marche (DE-OS  agree to impose a choice - or else an intermediate solution which does not allow, in a simple and easy way to immediately adapt the motorcycle to the conditions of the moment, and even possibly to adapt it during the ride (DE-OS

On connaît par ailleurs un motocycle à direction variable dans lequel l'inclinaison du tube de direction peut être adaptée aux conditions d'utilisation Dans ce cas, la fourche  There is also known a variable direction motorcycle in which the inclination of the steering tube can be adapted to the conditions of use In this case, the fork

Ce réglage de la direction ne peut s'effectuer qu'à l'arrêt et à l'aide d'outils et représente ainsi une solution  This steering adjustment can only be done when stationary and using tools and thus represents a solution
