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 as 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 a continuously adjustable or pre-set levels, according to 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 a 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 a high quality, anodised aluminium alloy. The diameter of the damping piston is 30mm, its supporting rod 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 a high quality, anodised aluminium alloy. The DTG – Series Double Tube Gas (DTG) shock absorbers, 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 an improved feedback along with a noticeably improved suspension, especially when compared to the original solution. SIP-TIP : Do not forget to order new damping rubbers, fixing nuts and bolts when replacing your shock absorber units.
