Wunderlich Suspension Shock absorber eS2 PRO

Facts and Product Features – Wunderlich Suspension powered by TracTive eS2 PRO Shock Absorbers

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

For extreme use: the PRO version. Extra reinforced, integrated, adaptive, electronically controlled high-performance shock absorber of the latest generation – as an upgrade or replacement for the original suspension. Developed for the highest demands of discerning adventure and touring riders as well as those who want additional safety reserves.

The exceptional performance of this shock absorber is convincing. It can be connected electronically to the motorcycle as plug & play without further adjustments. Selection and adjustment of the desired riding mode is done comfortably and as usual via the handlebar controls.

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

• Suspension Characteristics
• Our shock absorbers are specially developed for each vehicle and use case, offering high performance and impressive reserves
• The balanced, sensitive damping behaviour ensures a neutral, predictable ride and builds rider confidence and enjoyment
• They provide outstanding transparent feedback, optimise tyre grip, improve wheel guidance and tracking stability, and reduce tyre wear
• The shock absorber features the patented TracTive DDA valve (Dynamic Damping Adjustment) with impressive damping dynamics and performance, taking responsiveness to a new level
• The DDA valve is fully compatible with the motorcycle’s ECU and processes its control signals
• Compared to the stock suspension, the DDA valve has a wider adjustment range and responds significantly faster (6–10 ms)
• Individual damping adjustment: the high-quality shock offers high- and low-speed compression adjustment, depending on the speed of the compression stroke (i.e., the piston movement speed)
• The DDA valve and extensive individual compression settings meet the highest demands of adventure and touring riders. They noticeably increase comfort and safety and help reduce chassis stress
• For optimal, sensitive responsiveness:
• Generously sized oil channels reduce flow resistance to a minimum
• We use pistons with large diameters (46 mm)
• Low-friction seals and special shim stacks
• These closed systems feature an external forged aluminium reservoir for excellent thermal stability and optimal heat dissipation
• The large oil volume and extensive cooling surface ensure:
• Low, optimal oil operating temperature
• Stable high-level performance
• Extended shock absorber and oil service life

• Spring Properties and Preload
• Integrated electronic preload (EPA): except for the motorcycle’s original EPA unit, all components are replaced by TracTive high-performance parts
• Operation of the original EPA remains unchanged

• PRO
• PRO shock absorbers are the ultimate for extreme use: even more robust and optimised for reduced friction response through specially selected components and seals:
• Shock body made of steel
• Stainless steel bushings
• Special low-friction seals with added backup rings

• Tuning
• Special Wunderlich Suspension tuning for adventure and touring riders with high expectations

• Customisation
• We select the spring rate individually based on your personal riding profile – specify your data during the order process. This is the foundation for choosing the right spring for you

• Maintenance
• Every shock absorber can be fully serviced by the Wunderlich Suspension Centre
• Suspension tool included
