Wunderlich Suspension eS2 PRO shock absorber

Facts and product features of Wunderlich Suspension powered by TracTive eS2 PRO shock absorbers

The eS2 shock absorber line is an integrated, modular retrofit solution. With the exception of the standard electric spring preload (EPA), all other components are replaced by TracTive high-performance components.

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

The exceptional performance of this shock absorber is convincing. It can be connected electronically to the motorcycle Plug & Play and without any further adjustments. The desired riding mode can be selected and adjusted conveniently and as usual via the handlebar controls.

We select the spring rate individually with the help of your personal riding profile specifications.

• The damping characteristics
• Our shock absorbers are developed specifically for the respective vehicle and intended use, offering high performance and impressive reserves
• The balanced, sensitive damping behaviour of our suspension components ensures neutral, predictable handling and supports confidence in your own motorcycle, thereby enhancing personal riding enjoyment
• The shock absorbers impress with excellent, transparent feedback; they optimise the tyre’s contact with the road surface, wheel control and directional stability, and reduce tyre wear
• The shock absorber is equipped with the patented TracTive DDA damping valve (Dynamic Damping Adjustment), which impresses with its convincing damping dynamics and remarkable performance, taking responsiveness to a completely new level
• The DDA damping valve is fully compatible with the motorcycle’s control unit and processes its control signals
• Compared with the factory suspension, the DDA valve has a wider adjustment range and regulates significantly faster at 6-10 milliseconds
• Individual damping adjustment: The high-quality shock absorber features high- and low-speed compression damping adjustment, meaning the compression damping can be adjusted according to the speed of the compression movement, respectively the speed at which the damping piston moves during the process
• The DDA damping valve and the extensive options for individual compression damping adjustment meet the highest demands of adventure and touring riders. They noticeably increase comfort and safety and can help to reduce stress on the frame
• To achieve optimum, sensitive response,
• the oil channels are generously dimensioned to reduce the flow resistance of the oil to a minimum
• 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, which supports the system’s thermal stability and performance through optimum heat dissipation
• The generously dimensioned oil volume and the large cooling surface ensure
• a low, optimum operating temperature of the oil,
• which not only results in stable performance at the highest level,
• but also in a longer service life for the damper and the oil

• The spring characteristics and preload
• Integrated, standard electric spring preload (EPA): With the exception of your motorcycle’s standard electric spring preload unit (EPA), all other components are replaced by TracTive high-performance components
• Operation of the standard EPA remains unchanged

• PRO
• The PRO shock absorbers are the best shock absorbers for extreme use. They are built even more robustly and their response behaviour is optimised thanks to the selected components and seals with reduced friction. The following features distinguish the PRO shock absorbers:
• Steel shock absorber body
• Stainless steel bearing bushes
• Special seals with reduced friction and additional sealing, known as a back-up ring

• Set-up
• Special Wunderlich Suspension set-up for adventure and touring riders who place high demands on their suspension

• Customisation
• We select the spring rate individually with the help of your personal riding profile specifications: Once you have selected your shock absorber, simply define your personal specifications during the ordering process – they form the basis for our selection of the spring that suits you

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