Wunderlich Suspension Shock Absorber S4 - standard - rear

Facts and product features of the Wunderlich Suspension powered by TracTive S4 shock absorbers

High-performance shock absorber of the latest generation as an upgrade or replacement for the standard suspension. Developed to meet the high demands of discerning adventure riders who frequently go off-road, touring riders who often travel with heavy loads, and riders who want additional safety reserves. With PDS bottoming protection system and manual spring preload adjustment.

The spring rate is individually selected based on your personal riding profile specifications.

• Damping characteristics
• Our shock absorbers are specially developed for each specific motorcycle and its intended use, offering high performance and impressive reserves.
• The balanced and sensitive damping response of our suspension components ensures neutral, predictable handling, supporting rider confidence and enhancing riding enjoyment.
• The shock absorbers impress with their excellent feedback, optimising the connection between tyre and road surface, improving wheel control and directional stability, and reducing tyre wear.
• Individual damping adjustment: The high-quality shock absorber features both high- and low-speed compression damping adjustment, allowing fine-tuning of compression depending on the speed of the suspension movement (i.e. the speed of the damping piston during operation).
• The rebound damping adjustment with 18 clicks allows precise fine-tuning of the damping using the supplied suspension tool.
• The shock absorber is equipped with a so-called PDS system, which reduces the risk of bottoming out and the associated impact loads during hard use.
• The PDS system and the extensive options for individual rebound and compression adjustment meet the highest demands of adventure and touring riders. They noticeably enhance comfort and safety and help reduce stress on the frame.
• To achieve an optimal, sensitive response:
  • 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 enhances the system’s thermal stability and performance through optimal heat dissipation.
• The large oil volume and extensive cooling surface ensure:
  • an ideal operating temperature of the oil,
  • consistent top-level performance,
  • and extended service life of both the shock and the oil.

• Spring characteristics and preload
• Manual preload adjustment: The spring preload can be adjusted using the supplied suspension tool.
• The wide adjustment range compensates for a large variety of load conditions.

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

• Individualisation
• The spring rate is individually selected based on your personal riding profile specifications. After selecting your shock absorber, simply specify your individual parameters during the ordering process – they form the basis for selecting the spring that suits you best.

• Maintenance
• Each shock absorber can be completely serviced by professionals at the Wunderlich Suspension Centre.
• The suspension tool is included in the delivery.
