Wunderlich Suspension Cartridge C4 - standard - front

Facts and Product Features of Wunderlich Suspension powered by TracTive C4 Cartridge Sets

High-performance cartridge set of the latest generation as an upgrade or replacement for the stock suspension. Designed to meet the high demands of discerning adventure riders who frequently go off-road, touring riders who regularly carry heavy loads, and for riders who seek extra safety reserves. With the Hydro-Stop, a second damping stage that reduces the risk of bottoming out.

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

• Damping Characteristics
• Our cartridge sets are specially developed for each vehicle and application, offering high performance and impressive reserves
• The well-balanced, sensitive damping behavior of our suspension components ensures neutral and predictable handling, increasing confidence in your own motorcycle and enhancing personal riding pleasure
• The cartridges excel with outstanding transparent feedback, optimizing tire-road grip, wheel control, and stability while reducing tire wear
• The rebound and compression damping adjustment with 18 clicks allows individual fine-tuning of damping with the suspension tool
• To achieve optimal responsiveness,
  • the oil channels are generously dimensioned to minimize oil flow resistance
  • we use pistons with a large diameter (35 mm piston - the largest on the market)
  • as well as low-friction seals and special shim stacks
• The cartridge set is equipped with a so-called Hydro-Stop to prevent harsh bottoming out, where a second integrated damping piston forms an additional damping stage at high compression speeds
• The options of rebound and compression damping adjustment in combination with the Hydro-Stop reduce the risk of frame- and fork overloading, simultaneously increasing comfort and safety – not only off-road
• The closed aluminum cartridge housings support thermal stability and performance of the system through optimal heat dissipation
• The generous quantity of oil used ensures
  • low, optimal oil operating temperature
  • resulting in stable performance at the highest level
  • and extended lifespan of both the damper and oil
