KYB offers a mounting tool specially designed to facilitate the installation of spi seals on forks with diameters of 41, 43, 46 and 48 mm. It ensures perfectly centered guidance of the joint during installation, guaranteeing even, stress-free positioning. This tool effectively limits the risk of deformation, pinching or premature wear of the sealing lips during operation. It is ideal for maintenance and reconditioning operations on off-road motorcycle suspensions. Its robust design allows repeated use in the workshop, while maintaining high assembly reliability. Compatible with both 2-stroke and 4-stroke motocross and enduro bikes fitted with KYB forks, it is an essential tool for clean, professional suspension work.
