Since 1983, Thai manufacturer YSS develops and produces replacement and tuning shock absorbers in outstanding quality. In 1995, YSS received the quality control system YS9000 and ISO 9002 by German technical control board TÜV Rheinland. This was extended in 2005 by ISO/TS16949. Due to modern machinery, a high quality control standard and experienced employees working in R&D, YSS shock absorbers are increasingly found in all sorts of two-wheelers.

The absorber is made from aluminium and comes in top quality anodization. Piston diameter 30mm, piston rod 12mm.
