Wunderlich Suspension Shock absorber eS3 Adventure + EPA2 - For vehicles with factory lowering (-40 mm) - rear

Facts and product features of the Wunderlich Suspension powered by TracTive eS3-Adventure EPA2 shock absorbers

Electronically controlled and regulated high-performance shock absorber of the latest generation, designed as an upgrade or replacement for the standard suspension. Developed to meet the highest demands of discerning adventure and touring riders, as well as riders who desire additional safety reserves. With electric spring preload EPA.

The exceptional performance of this shock absorber is impressive. It can be connected electronically to the motorcycle plug & play without any further adjustments. The selection and adjustment of the desired riding mode are carried out conveniently and as usual via the handlebar controls.
We individually select the spring rate based on your personal riding profile specifications.

• Damping characteristics
• Our shock absorbers are specifically developed for the respective vehicle and intended use and offer high performance with impressive reserves
• The balanced, sensitive damping behaviour of our suspension components ensures neutral, predictable handling and supports confidence in the motorcycle, thereby enhancing personal riding enjoyment
• The shock absorbers stand out thanks to their excellent, transparent feedback; they optimise tyre contact with the road surface, wheel guidance 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 outstanding damping dynamics and remarkable performance, raising response behaviour to a completely 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 offers 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 adjustment, meaning that compression damping can be adjusted depending on the speed of the compression process (or the speed at which the damping piston moves during the process)
• The DDA damping valve and the extensive options for individual compression adjustment meet the highest demands of sport and touring riders. They noticeably increase comfort and safety and can also help reduce stress on the frame
• To achieve optimal, sensitive response behaviour,
  • the oil channels are generously dimensioned to minimise oil flow resistance
  • we use large-diameter pistons (46 mm)
  • as well as low-friction seals and special shim stacks
• These closed shock absorbers feature an external, forged aluminium reservoir that supports the system’s thermal stability and performance through optimal heat dissipation
• The generous oil volume and large cooling surface ensure
  • a low, optimal operating temperature of the oil,
  • which not only results in stable top-level performance,
  • but also in a longer service life of the damper and the oil

• Spring characteristics and preload
• Electric spring preload: the shock absorber is equipped with a sealed, extremely robust stepper motor drive for adjusting spring preload. Unlike many original electronic shock absorbers, the stepper motor is optimally protected inside the damper against the ingress of water or dirt. The robust preload adjustment mechanism withstands the harshest conditions
• The generous adjustment range compensates for a wide variety of load conditions

• Tuning
• Special Wunderlich Suspension tuning for adventure and touring riders who place the highest demands on their suspension

• Customisation
• We individually select the spring rate based on your personal riding profile specifications: after selecting your shock absorber, you simply define your personal specifications during the ordering process – they form the basis for selecting the spring that best suits you

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

Compatibility note

For all Euro 5 models, the original shock absorber splash guard cannot be reused in combination with the Wunderlich Suspension by TracTive shock absorber. Please therefore order the shock absorber splash guard set from your BMW dealer (Original BMW part no. 33548532478).
