Fork offset
The fork offset has an impact on the handling of the vehicle.
The fork offset can optionally be adjusted.
Fork offset is defined as the slanted position of the swivel axis in the direction of the longitudinal axis of the vehicle in relation to a verti-
cal line to the driving surface.
When both sleeves are installed in front of the A-arms, the fork offset increases. This enhances driving stability on fast raceways.
When both bushings are installed behind the A-arms, the fork offset decreases. This improves handling in bends.
Upon delivery one bushing is installed in front of the A-arm and one behind it.
