KYB offers a mounting ring specially designed to facilitate the installation of spinnaker seals on forks with diameters of 41, 43, 46 and 48 mm. It guides the joint during installation, ensuring perfectly straight and uniform positioning. This tool reduces the risk of deformation, pinching or damage to the sealing lips during installation. Its design is ideal for maintenance and reconditioning work on off-road motorcycle suspensions. It ensures faster, cleaner and more reliable assembly, even under intensive workshop conditions. Compatible with both 2-stroke and 4-stroke motocross and enduro bikes fitted with KYB forks, it is indispensable for professional suspension work.
