The Black-T shock absorber stage3 is a significant suspension upgrade for your BMW R18. The expansion tank of the stage3 shock absorber also facilitates fine compression adjustment and makes the high-performance separating piston design possible. The original BMW hydraulic spring preload with its hand wheel is still used and is integrated into the shock absorber. This allows for easy and precise adjustment of balance and damping to suit your requirements. The hydraulic spring preload allows loading to be adjusted for trips with two persons and/or luggage. Separate adjustability of tension and compression adds the finishing touches to this high-end fine tuning.
