Increased safety thanks to optimum chassis adjustment!
The linear winding of the fork springs enables optimum functioning on the road and the racetrack.
The recommended Wilbers fork oil SAE 7.5 (order no. 55040300020) with an air chamber of 90 mm should be used to adjust the shock absorbers with respect to the fork springs – a viscosity different from the original oil is permitted.
Lowered version includes reducing sleeves (fork inserts).
