The WP XACT PRO 7543 fork combines two of WP’s greatest technologies: The Cone Valve damping system and the AER spring system. This fork with split technology has been developed in close collaboration with current World Championship riders aboard many different motorcycle brands.The Cone Valve damping leg is an evolution of the traditional Cone Valve fork with damping optimized for use in combination with an AER spring leg.The AER spring leg was developed with maximum possible performance, almost unlimited configurations and the easiest possible handling in mind.
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.
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.
The CONE VALVE technology improves the turbulence-free oil flow through the damping piston by using a conical valve. This enables a linear damping performance with stiffer settings without loss of comfort.
