Wunderlich Suspension Shock absorber S2 PRO PDS - rear - Low -25mm

Facts and Product Features of Wunderlich Suspension powered by TracTive S2 PRO PDS Shock Absorbers

The S2 shock absorber line is an integrated, modular retrofit solution. Except for the standard electric preload adjuster (EPA), all other components are replaced with TracTive high-performance components.

For Extreme Use: The PRO Variant. Extra-reinforced high-performance shock absorber of the latest generation as an integrated, modular upgrade or replacement for the stock suspension. Designed for the highest demands of adventure riders who frequently venture off-road, touring riders who regularly carry heavy loads, and riders who desire extra safety margins. With the PDS bottoming control system.

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

• Damping Characteristics
• Our shock absorbers are specially designed for the specific vehicle and purpose, offering high performance and impressive reserves
• The balanced, sensitive damping behavior of our suspension components ensures neutral, predictable handling and enhances confidence in your own motorcycle, thereby increasing personal riding enjoyment
• The shocks score with excellent transparent feedback, optimizing tire-road interaction, wheel control, and track accuracy while reducing tire wear
• Individual damping adjustment: The high-quality shock absorber features high and low-speed compression damping adjustment, allowing the compression damping to be adjusted based on the speed of the compression process (or the speed at which the damping piston moves during the process)
• The rebound damping adjustment with 18 clicks allows individual fine-tuning of the damping with the suspension tool
• The shock absorber is equipped with a PDS system, which reduces the risk of bottoming out and the associated stress from hard hits during demanding use
• The PDS system, along with extensive options for individual adjustment of rebound and compression damping, meets the highest demands of adventure and touring riders. It significantly enhances comfort and safety and can help reduce frame stress
• To achieve optimal, sensitive responsiveness,
  • the oil channels are generously dimensioned to minimize 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, which supports thermal stability performance through optimal heat dissipation of the system
• The generous oil volume and large cooling surface ensure
  • a low, optimal oil operating temperature,
  • leading to stable performance at the highest level,
  • as well as extended shock absorber and oil lifespan

• Spring Characteristics and Preload
• Integrated standard electric preload adjuster (EPA): Except for the standard electric preload adjuster on your motorcycle (EPA), all other components are replaced with TracTive high-performance components
• The operation of the standard EPA remains unchanged

• PRO
• The PRO shock absorbers are the best choice for extreme use. They are even more robustly built, and their responsiveness is optimized due to the selected components and low-friction seals. The PRO shock absorbers feature the following characteristics:
  • Shock absorber body made of steel
  • Stainless steel bearing bushes
  • Special low-friction seals with additional sealing (known as a back-up ring)

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

• Customization
• We select the spring rate for the spring based on your personal riding profile specifications: After choosing your shock absorber, simply specify your personal specifications during the order process – they are the basis for selecting the right spring for you

• Maintenance
• Each shock absorber can be professionally serviced at the Wunderlich Suspension Center
• The suspension tool is included
