Adjustable shock BMW R1200GS (2004 – 2010) eX-TREME + EPA – Rear

This shock absorber uses a damping shim stack specifically developed for its application. The aluminum shock absorber housing creates maximum thermal stability by optimal heat removal. Not only leads this to stable performance but also to a longer lifetime of the shock and its oil. To create the best performance for every model we use high flow pistons, low friction seals, and dedicated shimstacks. We use heavy duty components like microfinished induction hardened quenched&tempered 42CrMo 16mm piston rods, best quality bearings and stainless steel bushings. Every shock can be opened and serviced, or tuned for the customer’s application. For all shocks there is a range of springs from softer than standard till harder.

This shock absorber fits plug and play into the motorbike with the original connector. This ensures that the original controls on the handlebar remain operational. There is no need for a cancelation kit or any other modification to the motorbike or its wiring harness. The shock absorber contains a very robust stepper motor actuator. Contrary to the orignal electronic shock absorber, the stepper motor is well protected inside the shock absorber and there are no issues with water ingress.

The main advantage of a damper with an external reservoir is that the shock absorber contains significantly more oil and also shows significantly more cooling surface than a shock absorber without a reservoir. It additionally offers the tuning capabilities to control the compression (ingoing) oil flow. Two separate adjusters control the damping respectivily at low shock absorber speed (slow undulations in the track/road) and at high shock absorber speed (sudden bumps or holes). The fixed piggybag fits nicely within the motorbike frame. The shock absorber is equipped with a so-called PDSII system against bottoming out. It has a 2nd damping piston mounted on top of the main damping piston. At the end of the ingoing shock absorber stroke, this 2nd damping piston enters a cup and creates an extra damping level. This happens only during the ingoing movement and only at high ingoing speeds. It effectivily is a cushion that absorbs the high ingoing energy and prevents a hard bottoming of the shock absorber. This leads to increased comfort and safety. At the same time the bottoming impacts on the motorbike frame are minimised, leading to less bent bolts and damages.

This shock absorber comes with a new electric preload adjuster with increased robustness and adjustment range.
