The composite shaft for the XLK900 Classic Series is made with six different materials. All six materials have exceptional vibration damping properties and three of the materials provide high strength and fatigue resistance. The foundation for the XLK is a precision lightweight core that is wrapped with several layers of unidirectional fibers with tensile strength equal to carbon fibers, but with better vibration damping properties. We chose Kevlar™ for the biaxial sleeve due to its exceptional tensile strength and tenacity. The epoxy we use to bond the fibers to each other and to the core is 3X stronger than conventional epoxy. The Kevlar™ is protected from UV degradation by a 0.25mm thick polymer applied over the fibers and UV resistant epoxy. The injection molded wheel forks are made from Du Pont’s™ toughest polymer and further strengthened during the molding process with short length carbon fibers.
