In this tutorial video we want to explain the installation of a Sip Performance shockabsorber into a VESPA scooter.
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 33% increase in stiffness or STO springs.
