Facts and Product Features of Wunderlich Suspension powered by TracTive S4 Shock Absorbers

Conventional high-performance shock absorber of the latest generation as an upgrade or replacement for the stock suspension. Designed for the high demands of demanding adventure riders who frequently go off-road and touring riders who regularly travel with heavy loads, as well as for riders who desire extra safety reserves. Equipped with the PDS bump stop system and manual spring preload. Including coded plug to suppress ESA message in the display.

We select the spring rate of the shock absorber based on your personal riding profile specifications.

  • Damping Characteristics
  • Our shock absorbers are specifically developed for each vehicle and application, offering high performance and impressive reserves
  • The balanced, sensitive damping behavior of our suspension components ensures a neutral, predictable handling, and supports confidence in your own motorcycle, enhancing personal riding enjoyment
  • The shock absorbers excel at providing excellent feedback, improving tire-road interaction, wheel control, and track accuracy , while reducing tire wear
  • Individual damping adjustment: The high-quality shock absorber features high and low-speed compression damping adjustment, allowing you to adjust compression damping based on the speed of the compression stroke (i.e., the speed at which the damping piston moves during the stroke)
  • The rebound damping adjustment with 18 clicks allows fine-tuning of the damping using the suspension tool
  • The shock absorber is equipped with a PDS system, which reduces the risk of bottoming out and the associated stress from hard hits during demanding use
  • The PDS system, along with extensive options for individual adjustment of rebound and compression damping, meets the highest demands of adventure and touring riders. They significantly enhance comfort and safety and can help reduce frame stress
  • To achieve optimal, sensitive responsiveness,
    • the oil channels are generously sized to minimize oil flow resistance
    • we use pistons with a large diameter (46 mm)
    • as well as low-friction seals and special shim stacks
  • These sealed shock absorbers feature an external forged aluminum reservoir, supporting thermal stability and system performance through optimal heat dissipation
  • The generous oil volume and large cooling surface
    • ensure a low, optimal oil operating temperature,
    • resulting not only in stable performance at the highest level,
    • but also in extended shock absorber and oil life
  • Spring Characteristics and Preload
  • Manual spring preload: Spring preload can be adjusted with the included suspension tool
  • The generous adjustment range can compensate for a wide range of load conditions
  • Tuning
  • Special Wunderlich Suspension tuning for adventure and touring riders with high demands on their suspension
