FOR RACE USE ONLY

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 25 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.

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 2 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.

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.

Conclusion: A successful alternative to conventional shock absorbers which not only convince thanks to their technical features but also through their style and their design quality.

 

 

 

 

 

SIP Performance shock absorber, rear

- gas shock absorber filled with nitrogen gas, spring preload continuously adjustable, progressive spring, 2 lock rings for adjustment -> safeguard against unintended adjustment, rebound adjustment: 20 different levels (?Clicks?), strong 12.5mm damper rod, additional guide plate for upper rubber (front), optimized fitting accuracy through CNC machining, high-quality materials and addtional surface refinement and anti-corrosion coating, adjusting tool included in delivery, L=204mm

 

SIP-TIPP: there are steering columns and distance bushings for the rear shock absorber by various manufacturers and with different tolerances. If there is a clearance between the shock absorber and the seating, please adjust this clearance by using the adjusting washer kit 0.25 and 0.5mm at the front as well as by using a washer at the rear. Customers purchasing a SIP Performance shock absorber will get the adjusting washer kit for free.

 

Mike Betz, German Scooter Forum, August 2010:

"This weekend the Berlin GP took place on a track that was literally made of bumps and potholes. I easily won both races and drove top times on my standard class scooter, even faster than most of the Falcs and Quattrinis. This was certainly due to the new suspension. After a little adjustment, the scooter was running as smoothly as a train on tracks. The force is strong with the rear SIP shock and its new -20% spring!"

 

Dirk Schlemme, German Scootermagazine VESPINA - August´2010:

"I fit some Performance - Shock absorbers on PX modells the last weeks for good friends and I have to say - these shock absorbers are the best which you can get at the moment!"
