Device for fixing the front end assembly of a motorcycle includes an upper plate, a lower plate, a column shaft linking the two plates by enclosing the chassis column tube. The bearings originally mounted are replaced by an assembly of parts and the swivel joint element. The rotating elements are placed in the plate and the plate respectively to allow them to rotate on the column shaft locked in rotation by the part. The groove of the part and the cylindrical surfaces of parts with axis perpendicular to a median plane of the vehicle and passing through the center of the swivel joint allow the entire device to pivot about the axis to offset the column shaft with the axis of the tube thereby modifying the caster angle. The rotating element mounted in an oblong configuration enables the offset on the plate to be modified and by tilting about the axis and tilting of the plate about the axis enables the value of the ground caster distance and the inclination of the suspension element to be modified.
