Whether heading for a National Roadracing title or just taking your bike to the local race track, the cartridge kit offers loads of performance, stability and superior suppleness. This kit has a unique design, where the compression damping is taken care of the left fork leg while the other controls rebound damping. This allows not only for a more precise function and better stability, but also the possibility of having all adjustments conveniently placed at the top of the fork, together with the spring preload adjusters. The cartridge kit fits bolt on and is easy to install in most standard hypersport front forks.  Note! This kit requires springs and oil which are sold separately.  The 08423-series of front fork springs are available to order separately to suit the rider’s choice of spring rate.
