Wunderlich Suspension Cartridge C4

Facts and product features of the Wunderlich Suspension powered by TracTive C4 cartridge set

Latest-generation high-performance cartridge set as an upgrade or replacement for the standard suspension. Developed for the demanding requirements of ambitious adventure riders who frequently ride off-road, touring riders who regularly travel with high payloads, and riders seeking additional safety reserves. Featuring Hydro-Stop, a second damping stage that reduces the risk of bottoming out.

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

• Damping characteristics
• Our cartridge sets are developed specifically for each vehicle and its intended use, delivering high performance and impressive reserves
• The balanced, sensitive damping behaviour of our suspension components ensures neutral, predictable handling and strengthens rider confidence, enhancing overall riding enjoyment
• The cartridges impress with excellent, transparent feedback, optimising tyre contact with the road surface, wheel guidance and directional stability while reducing tyre wear
• Rebound and compression damping adjustment with 18 clicks allows precise individual fine-tuning using the suspension tool
• To achieve optimum, sensitive response behaviour,
• the oil channels are generously dimensioned to minimise oil flow resistance
• large-diameter pistons are used (35 mm pistons – the largest on the market)
• as well as low-friction seals and special shim stacks
• The cartridge set features a so-called Hydro-Stop to prevent harsh bottoming out, in which a second integrated damping piston forms an additional damping stage at high compression speeds
• The rebound and compression adjustment options in combination with the Hydro-Stop reduce the risk of overloading the fork and frame while simultaneously increasing comfort and safety – not only off-road
• The closed aluminium cartridge housings support the system’s thermal stability and performance through optimal heat dissipation
• The generously dimensioned oil volume ensures
• a low, optimal operating oil temperature,
• which not only guarantees stable high-level performance,
• but also extends the service life of both damper and oil

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

• Tuning
• Wunderlich Suspension for the highest demands

• Customisation
• We individually select the spring rate based on your personal riding profile specifications: after selecting your cartridge set, you simply define your personal specifications during the ordering process – they form the basis for selecting the spring that perfectly suits you

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