Wunderlich Suspension S4 Shock Absorber - Lowering by -20 mm - rear

Facts and Product Features of Wunderlich Suspension powered by TracTive S4 Shock Absorbers

High-performance shock absorber of the latest generation, designed 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 regularly travel with heavy loads, and riders seeking additional safety reserves. Equipped with PDS anti-bottoming system and manual spring preload adjustment.

We individually select the spring rate according to your personal riding profile specifications.

• Damping characteristics
• Our shock absorbers are specifically developed for each motorcycle and its intended use, offering high performance and impressive reserves
• The balanced, sensitive damping behaviour of our suspension components ensures neutral and predictable handling, promoting rider confidence and increasing riding enjoyment
• The shock absorbers stand out for their excellent, transparent feedback: they optimise tyre-to-road contact, wheel guidance and directional stability, while reducing tyre wear
• Individual damping adjustment: this premium shock absorber features high- and low-speed compression adjustment, meaning that the compression damping can be tuned depending on the speed of the compression stroke (i.e. the speed at which the damping piston moves during the stroke)
• The rebound adjustment with 18 clicks allows precise fine-tuning of the damping using the suspension tool
• The shock absorber is equipped with a PDS (Progressive Damping System) that reduces the risk of bottoming out and the associated stress from hard impacts during demanding use
• The PDS system, along with the extensive options for individual rebound and compression adjustment, meets the highest demands of adventure and touring riders. It noticeably increases comfort and safety and can also help reduce stress on the frame
• To achieve optimal, sensitive responsiveness,
  • 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 consistently stable performance at the highest level,
  • but also extends the service life of the damper and the oil

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

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

• Customisation
• We individually select the spring rate according to your personal riding profile specifications: after choosing your shock absorber, you can specify your personal parameters during the ordering process – these form the basis for selecting the spring best suited to you

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