TracTive X-TREME Front Shock / R1250GS ’18-On

This shock comes with a cancellation box allowing you to have fully manual rebound and hi & low speed compression adjustability while still having auto-load leveling and ESA rebound dampening in the rear. Combine with 46BM18-T5729 for full manual dampening while keeping electronic preload adjustability.

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 micro finished 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 shows also 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 respectively at low shock absorber speed (slow
undulations in the track/road) and at high shock absorber speed (sudden bumps
or holes). By using a hose-connection the reservoir and adjusters can be
conveniently positioned. The hoses and fittings used in the shock absorbers
have a very large internal cross-section, and therefore there is no hydraulic
restriction in this construction except at the compression adjusters. 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 effectively 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 minimized, leading to less bent bolts and damages.
