Abstract
Abstract In a motorcycle, in order to adapt the angle of in-clination of the steering device (10, 13) for different speeds, the steering support (11) is mounted to be swing-able (15) on the frame of the motorcycle and the mentioned angle is adjusted by means of an angle adjusting device.
The adjusting device preferably comprises an eccentric arrangement with adjusting means (37, 35) that are control-led manually or in dependence upon output signals from a speed sensor (39).
