Facts and Product Features of Wunderlich Suspension powered by TracTive eS1 EPA Shock Absorbers

The eS1 EPA shock absorber is the first upgrade for riders looking to optimize their electronically controlled and regulated stock suspension or replace an aging stock suspension with a higher-quality alternative. This high-quality all-around shock absorber features damping settings specifically developed for the respective vehicle model and intended use, primarily targeting touring riders with the highest demands on their suspension. Equipped with electric spring preload (EPA).

The exceptional performance of this shock absorber is convincing. It can be connected electronically to the motorcycle as a plug & play solution without further adjustments.The desired riding mode can be selected and set conveniently using the handlebar controls.
We select the spring rate of the spring based on your personal riding profile specifications.

  • Damping Characteristics
  • Our shock absorbers are specially developed for each vehicle and purpose, offering 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 transparent 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 impresses with its convincing damping dynamics and impressive performance, taking responsiveness to a whole new level
    • The DDA damping valve is fully compatible with the motorcycle's control unit and processes its control signals
    • Compared to stock suspension, the DDA valve has a larger adjustment range and regulates much faster, with 6-10 milliseconds
  • The compression damping adjustment allows individual fine-tuning of damping with the suspension tool
  • With a range of 18 clicks, an individually balanced damping setting can be adjusted, with each click producing a noticeable change in damping
  • To achieve optimal responsiveness,
    • nitrogen and damper oil are separated by the piston in the shock absorber housing,
    • we use pistons with a large diameter (46 mm) to minimize oil flow resistance,
    • as well as low-friction seals
  • The generous quantity of oil used ensures
    • optimal oil operating temperature,
    • stable damper performance,
    • a longer lifespan of the shock absorber and oil
  • Spring Characteristics and Preload
  • Electric spring preload: The shock absorber is equipped with a sealed, robust stepper motor drive for adjusting spring preload. Unlike many original electronic shock absorbers, the stepper motor inside the damper is optimally protected from water or dirt ingress. The robust preload adjustment device can withstand the toughest conditions
  • The generous adjustment range can compensate for a wide range of load conditions
  • Tuning
  • Special Wunderlich Suspension tuning for touring riders with high demands on their suspension
  • Customization
  • We select the spring rate of the spring 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
