Wunderlich Suspension Shock Absorber S4 - Lowering by -25 mm - 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 ride off-road, touring riders who regularly travel with heavy loads, and riders who want additional safety reserves. With PDS anti-bottoming system and manual preload adjustment.

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

• Damping characteristics
• Our shock absorbers are specifically developed for each vehicle and intended use, offering high performance and impressive reserves.
• The balanced and sensitive damping response of our suspension components ensures neutral and predictable handling, supporting rider confidence and enhancing riding pleasure.
• The shocks impress with their excellent, transparent feedback – they optimise tyre-to-road contact, wheel guidance, and directional stability while reducing tyre wear.
• The rebound and compression adjustment allows for fine individual tuning of the damping using the suspension tool.
• With 18 clicks of adjustment, the damping can be individually balanced, with each click producing a noticeable change in the damping response.
• To achieve an optimal, sensitive response:
  • the oil channels are generously dimensioned to minimise oil flow resistance,
  • we use large-diameter pistons (46 mm),
  • and low-friction seals combined with specially tuned shim stacks.
• The closed shock absorber features an external forged aluminium reservoir that improves thermal stability and performance through optimal heat dissipation.
• The generous oil volume and large cooling surface ensure:
  • a consistently low and optimal oil operating temperature,
  • stable damping performance at the highest level,
  • and extended service life of both the damper and oil.

• Spring characteristics and preload adjustment
• Manual spring preload: The 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 setup.

• Individualisation
• We select the spring rate individually based on your personal riding profile specifications: after selecting your shock absorber, you simply specify your individual parameters during the ordering process – these form the basis for our spring selection to suit you perfectly.

• Maintenance
• Each shock absorber can be fully serviced by specialists at the Wunderlich Suspension Center.
• The suspension tool is included in the scope of delivery.
