SIP Performance shock absorbers for all Vespa models with a separate spring and damper suspension. Aluminium, CNC machined, anodised

Almost all shock absorbers currently available for Vespa models with a separate spring and damper suspension have no effective damping function, mostly due to their technical layout. Even shock absorbers with adjustable compression damping provide a noticeably stiffer suspension, although the expanding spring is not damped or slowed. This leads to the shock absorber expanding quickly, sending a jolt through the handlebars.

One of the main aims in designing the SIP performance shock absorber was to provide optimal damping during the rebound phase. The rebound damping ensures a clean and even shock absorber expansion at a controllable rate. This causes, for example during braking, the front end of the scooter to recover softly and remain controllable without acting like a pogo stick! The damping process takes place in two seperate chambers, one filled with gas, the other with oil. Shock bushes are made out of polyurethane rubber.

These shock absorbers are available with two separate grades of stiffness :

60 PSI: for comfortable riding or race track useage

100 PSI: for XXL guys or lots of luggage

The stiffer the damper the higher the PSI rating (the quicker the rebound). Another important factor is the choice of spring. We recommend springs with at least a 25-33% increase in stiffness.

Mounting instructions: Before installing, check the upper and lower screws for fastening the shock absorber to the eye. Unfortunately, depending on the supplier, these are not always true to size and have to be reworked.

When the spring is too weak the shocker over compresses creating an ineffective angle on the trailing link suspension. A stiffer spring is required.
