We are now an Official WP distributor for sales and repairs. Forks to fit KTM XCF250, SXF250. Husqvarna FX350The AER 48 Cone Valve 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 optimised for use in combination with an AER spring leg. The AER spring leg was developed with the highest possible performance, nearly unlimited possible set-ups and easiest possible handling in mind. The WP Motorsports Cone Valve technology permits almost limitless damping performance due to an unique valving system. The set-up of a conventional damping system has always been a compromise between sufficient comfort and bottoming resistance, whereas the Cone Valve technology now permits a combination of both factors, resulting in outstanding damping behaviour in all riding situations. The AER spring allows the rider to set up the fork for his individual requirements and for individual tracks without changing any internals. Two chambers that can be set up individually, allowing the rider to improve the comfort throughout the entire stroke in combination with great initial response. The bikes riding balance can be changed independently of the bottoming resistance. Also, the AER technology saves up to >1kg compared to other competition forks.
