Tractive Rear Shock X-CELLENT + HPA (OEM Low) for BMW S1000XR (2015-2019)

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 is the choice for customers that want to adjust damping between different tracks or want to have optimal damping control. Using the rebound adjuster, the damping is adjusted with approximately 18 clicks. Every clicker adjustment brings a noticeable change in damping level.

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 robustness of the preload adjuster allows to ride in the harshest conditions and highest loads without any issues. The large preload adjustment range of 15 mm (unless otherwise specified) is typically double the stock range and a lot more than almost all aftermarket brands. It allows for load compensation and for optimising the balance in the motorcycle. The PA can be finely adjusted in more than 60 clicks. The hose connection allows for a convenient positioning of the adjuster knob.
