The spacers allow motorcycles to be lowered at the rear. The spacer is simply installed in the shock absorber, more precisely between the retaining ring of the sealing head and the sealing head itself. This limits the stroke of the shock absorber as the shock absorber can now rebound less by the height of the spacer.
Example: With the 6mm spacer, the stroke of the shock absorber is shortened by 6mm; on most motorcycles, this corresponds to a reduction in suspension travel of around 20mm and therefore a 20mm lower position of the rear end. With the 10mm spacer, the rear end would be lowered by around 30mm. The installation of the spacer has no effect on the function of the shock absorber. The spacer can be removed again to return the bike to its original height.
