ABSTRACT:
A front wheel suspension of a motorcycle includes a front wheel fork with an upper fork bridge and a lower fork bridge. A bell crank is pivotally connected at the lower fork bridge by way of a ball joint located in the wheel center plane; two guide arms are pivotally connected at the rear corner area of the bell crank by way of a bearing shaft which in their turn are pivotally connected at the motorcycle frame. Two lever arms project upwardly from the bell crank, at the end sections of which one guide member each is pivotally connected by way of a bearing bolt; the guide members in turn are also pivotally connected at the motorcycle frame. During the inward spring movement of the front wheel fork, the ball joint of the bell crank is displaced slightly forwardly and the resulting wheel base change is reduced thereby.
