Shock Absorber Vespa (Rear) SIP Performance - PX, PE, DISC, T5, T5 CLASSIC

New Version 2 type

"Gas shock absorber filled with nitrogen gas, spring preload continuously adjustable, progressive spring, rebound adjustment- 20 different levels (Clicks), strong 14mm damper rod (with the 2.0 version), L=340mm, CNC machining, aluminium, incl. screw for lower rear seating, seating: thread/fork

On the basis of a German development we are now able to present a modern and innovative suspension which catapults the Vespa straight into the 'here and now'! The result is the SIP PERFORMANCE range of shock absorbers from precisely CNC milled construction elements, almost unlimited settings options and a range of additional gimmicks. All of the experience we have gained over 30 years was incorporated in the development. Prior to entering batched production, the SIP Performance shock absorbers were also tested at clutch and suspension specialists Sachs (since 2001, ZF Friedrichshafen AG) in Schweinfurt. Bitubos and similar gas pressure shock absorbers were used as objects of comparison. The test results supported our initial work and the idealistic conception of a Vespa shock absorber.

Features such as the continuously variable spring preload, a genuinely progressive spring and adjustable rebound damping are just a part of the sophisticated features. Technical refinements such as a 12.5 mm thick rise bar, hardened light weight materials and an additional guide plate for the upper rubber bearings all provide additional stability in the suspension. High quality materials are as straightforward as the precise and detailed CNC production and a perfect finish including surface protection. A comprehensive fixings kit for the lower engine fastening is included in the delivery of the SIP Rear Shock Absorber unit. This kit contains nuts and bolts suitable for all common lower engine fastening sizes (M9 and M10). We also include spacer washers in order to compensate for the varying production tolerance guidelines of the different producers of steering columns and shock absorber fixings.

We have concentrated on providing a more comfortable ride for tourers over longer distances and poor road surfaces with the 2.0 series of our shock absorbers. The diameter of the damper rod has been increased to 14 mm, the lower mounting bracket has been reinforced and the overall design and the inner technology have also been redeveloped. The unit has a wide variety of set-up possibilities, right from very comfortable to sportingly taut.

Spring preload: The continuously variable spring preload means the shock absorber springs can be given a tighter basic setting - the forces compressing the spring thus meet an early counterforce. The spring preload occurs via counter rings, which, when effectively counter-rotated, guarantee an effective degree of safety against unwanted adjustments. The adjustment tool is naturally also supplied.

Progressive springs: Our shock absorbers are also equipped with a progressive spring which means the clearances between the spring coils become progressively lower (progressive). Only progressively coiled springs permit a genuinely comfortable response when braking or riding either with luggage or a passenger, which means the spring initially responds very sensitively but gets 'stiffer' in the case of further spring compression/loading. In order to be able to tailor their individual performance to cater for the larger riders amongst us, or other heavy loads, we also have a selection of springs available in varying stiffness壽_蹄太s and colours.

Setting the rebound damping: The rebound damping gives a positive finish to the overall picture and influences the extension characteristics of the shock absorber, which means it regulates the response when driving over uneven road surfaces and potholes and also when braking. Depending on the model between 10 and 20 different possible settings ('clicks') for the rebound level are available. On turning the rebound damping in a clockwise direction the damping level increases, when turning it in an anticlockwise direction it lessens (direction of view = plan view).

Info: On the Grimeca disc brakes it may be necessary to adjust the shock absorber attachment slightly. The ex-works plastic coating often has very big variations in terms of the thickness of the coating. This is straightforward and easy to do by yourself."
