Wunderlich Suspension Cartridge C4 - Lowering by -30 mm - front

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

High-performance cartridge set of the latest generation 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 who desire additional safety reserves. With Hydro-Stop, a secondary 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 specially developed for each vehicle and intended use, offering high performance and impressive reserves.
• The balanced, sensitive damping behaviour of our suspension components ensures neutral and predictable handling, supporting confidence in your motorcycle and thereby enhancing your riding pleasure.
• The cartridges impress with their excellent transparent feedback; they optimise tyre-to-road contact, wheel control and tracking stability, and reduce tyre wear.
• The rebound and compression damping adjustment with 18 clicks allows individual fine-tuning using the suspension tool.
• To achieve optimal, sensitive responsiveness,
  • the oil channels are generously dimensioned to minimise flow resistance,
  • we use large-diameter pistons (35 mm – the largest on the market),
  • and low-friction seals with special shim stacks.
• The cartridge set is equipped with a so-called Hydro-Stop to prevent harsh bottoming out: a second integrated damping piston provides an additional damping stage at high compression speeds.
• The combination of rebound and compression damping adjustment with the Hydro-Stop reduces the risk of overloading the fork and frame, while increasing comfort and safety – not only off-road.
• The closed aluminium cartridge housings support thermal stability and system performance through optimal heat dissipation.
• The generously dimensioned oil volume ensures
  • a low, optimal operating temperature of the oil,
  • which not only ensures stable performance at the highest level,
  • but also extends the service life of both damper and 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 large variety of load conditions.

• Adjustment
• 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, simply specify your personal data during the order process – this forms the basis for selecting the spring best suited to you.

• Maintenance
• Each cartridge can be completely and professionally serviced at the Wunderlich Suspension Centre.
• The suspension tool is included in the delivery.
