Tractive BMW R 1250 GS Adventure Rear Shock X-TREME

Note: Original mudguard to be re-used, Electronic damping cancelling kit included.Ultimate performance shock absorber with adjustable rebound and high- and low-speed compression damping. Electronic preload adjustment. PDSII anti bottoming.

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 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.

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