This aluminium cartridge system can be added to original forks. The cartridge system considerably improves the whole suspension of the motorcycle. This WP system has an internal reservoir. By pressurizing the oil in this reservoir the damping is much more consistent. WP is the first and only manufacturer to offer a closed-cartridge-system for standard front forks. Developed for the racetrack, the cartridge system has no hydraulic stroke limitation, so that the rider can continually control the suspension characteristics. The system can be fully adjusted externally. By use of high quality, lightweight material it considerably reduces the weight of the original fork.
