YSS Rear suspension units are a high quality but affordable emulsion gas shock replacement for OE parts. They are available as either mono or twin shocks, for machines from the 1970s right up to modern superbikes. All YSS Shock Absorbers are built with carefully chosen materials to protect against corrosion as well as reducing the overall weight of the shock, making this unit a cost effective alternative to its OEM equivalent, while at the same time offering greater range of adjustment.
