Wunderlich Suspension Cartridge C4 - standard - front

Facts and product features of the Wunderlich Suspension powered by TracTive C4 Cartridge Set

High-performance cartridge set 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 ride off-road, touring riders who regularly travel with heavy loads, and riders who want additional safety reserves. Equipped with a Hydro-Stop system, a second damping stage that reduces the risk of bottoming out.

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

• Damping characteristics
• Our cartridge sets are developed specifically for each vehicle model and its intended use, offering high performance and impressive reserves
• The balanced, sensitive damping behaviour of our suspension components ensures neutral, predictable handling, building rider confidence and enhancing riding enjoyment
• The cartridges deliver excellent feedback, optimising tyre grip, wheel guidance, directional stability and reducing tyre wear
• The rebound and compression damping adjustment with 18 clicks allows precise fine-tuning of the damping using the supplied suspension tool
• To achieve optimal, sensitive response,
  • the oil channels are generously dimensioned to minimise flow resistance
  • we use large-diameter pistons (35 mm – the largest on the market)
  • as well as low-friction seals and special shim stacks
• The cartridge set features a so-called Hydro-Stop system that provides protection against harsh bottoming out, with a second integrated damping piston forming an additional damping stage at high compression speeds
• The combination of rebound and compression adjustment options and the Hydro-Stop system reduces the risk of excessive stress on the fork and frame while improving comfort and safety – both on and off the road
• The closed aluminium cartridge housings ensure thermal stability and consistent performance through optimal heat dissipation
• The generously dimensioned oil volume provides
  • an optimally low operating temperature for the oil,
  • which results in consistent top-level performance,
  • and extends the service life of both the damper and the oil

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

• Setup
• Wunderlich Suspension tuning for demanding riders

• Individualisation
• We select the spring rate individually based on your personal riding profile specifications: after you have chosen your cartridge set, simply specify your personal parameters during the ordering process – they serve as the basis for selecting the spring that perfectly matches you

• Each cartridge can be professionally and fully serviced at the Wunderlich Suspension Center
• The suspension tool is included in the delivery
