Abstract: A suspension system for the front wheel of a motorcycle, comprising a ball joint fork, which is rotatably and swivellably connected with the vehicle frame; a suspension element which is connected with the vehicle frame and by way of a ball joint is connected with a lower fork bridge; and spring elements which are supported on a movable part of the suspension system and on the vehicle frame. The suspension element is constructed as a central suspension element with a linear suspension function and is rigidly connected to the forward frame of the motorcycle.

Abstract: A safety installation for single track vehicles, especially motorcycles, which enables the driver of the motorcycle to be thrown over an obstacle, particularly in case of lateral impact against a passenger motor vehicle; a support element with a deflection surface is provided for that purpose ahead of the driver; the support element, which can be constructed as tank-mounted carrier, is rotatably supported to the motorcycle frame about an axis of rotation which extends as a cross axis which is disposed ahead of and below the deflection surface.
