Wunderlich Suspension Shock absorber eS2 ST - rear - standard

Facts and Product Features of Wunderlich Suspension powered by TracTive eS2 ST Shock Absorbers

The eS2 ST shock absorber line is an integrated, modular retrofit solution. Except for the standard electrical spring preload adjuster (EPA), all other components are replaced with TracTive high-performance components.

Integrated, adaptive, electronically controlled high-performance shock absorber of the latest generation, designed as an upgrade or replacement for the standard suspension. Developed for the highest demands of demanding sports and touring riders, as well as riders seeking additional safety reserves.

The exceptional performance of this shock absorber is convincing. It can be connected electronically to the motorcycle via plug & play without further adjustments. The desired riding mode can be selected and set conveniently using the handlebar controls.

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

• Damping Characteristics
• Our shock absorbers are specifically developed for each vehicle and application, providing high performance and impressive reserves.
• The well-balanced, sensitive damping behavior of our suspension components ensures neutral and predictable handling, increasing confidence in your own motorcycle and enhancing personal riding pleasure.
• The shock absorbers excel with excellent feedback, optimizing tire-road grip, wheel control, and stability, while reducing tire wear.
• The shock absorber is equipped with the patented TracTive DDA damping valve (Dynamic Damping Adjustment), which stands out with convincing damping dynamics and impressive performance, raising responsiveness to an entirely new level.
  • The DDA damping valve is fully compatible with the motorcycle's control unit and processes its control signals.
  • Compared to the factory suspension, the DDA valve has a larger adjustment range and regulates significantly faster in 6-10 milliseconds.
• Individual damping adjustment: The high-quality shock absorber features high and low-speed compression damping adjustment, meaning that compression damping can be adjusted depending on the speed of the compression stroke (or the speed at which the damping piston moves during the stroke).
• The DDA damping valve and extensive options for individual compression damping adjustment meet the highest demands of sports and touring riders and noticeably increase comfort and safety.
• To achieve optimal and sensitive responsiveness,
  • the oil channels are generously dimensioned 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 closed shock absorbers feature an external, forged aluminium reservoir that supports thermal stability and performance through optimal heat dissipation.
• The generous oil quantity and large cooling surface ensure
  • a low, optimal oil operating temperature,
  • resulting not only in stable performance at the highest level,
  • but also in an extended service life for the damper and oil.

• Spring Characteristics and Preload
• Integrated standard electrical spring preload adjuster (EPA): Except for the standard electrical spring preload adjuster (EPA) of your motorcycle, all other components are replaced with TracTive high-performance components.
• The operation of the standard EPA remains unchanged.

• Tuning
• Special Wunderlich Suspension tuning for sports and touring riders with high demands on their suspension.

• Customization
• The spring rate of the shock absorber is selected individually based on your personal ride profile specifications. After choosing your shock absorber, simply determine your personal specifications during the ordering process. These serve as the basis for selecting the appropriate spring for you.

• Maintenance
• Each shock absorber can be professionally serviced at the Wunderlich Suspension Center.
• The suspension tool is included in the scope of delivery.
