TECHNOLOGY

Closed Cartrigde

CLOSED CARTRIGDE

By compartmentalizing the damping system on CLOSED CARTRIDGE forks, it is possible to reduce the oil volume. Pressure in the system prevents cavitation and ensures reliable damping performance in demanding track conditions.

KEY FEATURES

    • Open Cartridge system
    • Fully accessible adjustment units
    • Extremely fine sensitivity due to friction-optimized coating on inner and outer tubes
    • Light weight construction
    • Fully adjustable with standard tools
    • Standard in the KTM RC 390 Cups around the world
The WP APEX PRO 6543 Fork has been developed based on our know-how from the race track and provides excellent damping results combined with outstanding response. The driver can handle the motorcycle more skillfully and has outstanding control. The WP APEX PRO 6543 Fork was first developed for the German ADAC cup. A open cartridge system combined with high quality coated tubes ensures highest performance and responsiveness. It is completely adjustable in compression, rebound and spring preload, which enables an individual setup.

WP TECHNOLOGY

 
AER TECHNOLOGY
The AER technology significantly reduces the overall weight. In addition, the AER system allows an uncomplicated optimization of the damping performance and adaptation to the track without opening the fork.
 
CLOSED CARTRIGDE
By compartmentalizing the damping system on CLOSED CARTRIDGE forks, it is possible to reduce the oil volume. Pressure in the system prevents cavitation and ensures reliable damping performance in demanding track conditions.
 
CONE VALVE
The CONE VALVE technology improves the turbulence-free oil flow through the damping piston by using a conical valve. This results in a much better response and a lower initial breakaway torque.
 
LINKED DAMPING SYSTEM
The LINKED DAMPING technology optimizes the progression of the entire shock absorber via a linkage attached to the swing arm. This enables perfect grip and sufficient damping reserves.
 
OPEN CARTRIDGE
Due to the increased oil volume in the damping system, the OPEN CARTRIDGE technology enables optimized heat dissipation with reduced friction. This ensures constant damping performance despite increased stress.
 
PROGRESSIVE DAMPING SYSTEM
PROGRESSIVE DAMPING technology generates a progressive damping characteristic with increased damping performance in the last third of the suspension travel, resulting in a reduction in weight and maintenance.
 
SUPERTRAX
SUPERTRAX technology perfects the TRAX System. SUPERTRAX detects missing ground contact and enables faster rebound by opening a bypass oil valve. The rider has 100% control over the speed of the rebound movement thanks to fully variable adjustment of the rebound damping.
 
TRAX TECHNOLOGY
The TRAX technology detects missing ground contact and enables a faster rebound by opening a bypass oil valve. Traction and acceleration are improved and handling is optimized.
