The Thai manufacturers YSS have been producing high quality replacement and sporting upgrade shock absorber systems since 1983. Due to their German MOT certification and approval for use with almost all modern Vespa models, they are not only 100% road-legal but can be considered a valid alternative to the (also road-legal) BITUBO units. 

Mono X-Pro series oil-pressured shock absorbers represent an economically priced upgrade from the original items. These specially developed units possess a 'double-action' damping system and the pre-load on the spring can also be adjusted with either continuously adjustable or pre-set levels, according to the model. The progressive damping, combined with a solidly proportioned damping piston rod, guarantees a safer riding experience and better handling, whatever the load or road conditions. 

Mono/Twin Pro E-series gas-pressured shock absorbers. Top-quality meets top performance. The 'E-series' gas-pressured Emulsion shock absorbers are damped with a combination of nitrogen gas and a hydraulic oil which results in solid reactions and high durability. The finest components, such as the sintered seal solid gasket and the 12mm hard-chromed damping piston rod are also included. The spring pre-load is continuously adjustable and the main body of the damping reservoir is constructed using high quality, anodised aluminium alloy. The diameter of the damping piston is 30mm, and its supporting rod is 12mm.

J-series gas-pressured shock absorbers with an encapsulated aluminium damping reservoir body and progressive damping characteristics. The main body of this unit is produced using high quality, anodised aluminium alloy.

The DTG – Series Double Tube Gas (DTG) shock absorbers, are filled with both nitrogen gas and oil. These elements, combined with a progressively-wound spring and the two-chamber gas-hybrid system from the DTG series deliver improved feedback along with a noticeably improved suspension, especially when compared to the original solution.
