Rear suspension element
Adjusting the rear suspension element
of all Scorpion models
Danger!
While adjusting the rear
suspension element never load the tricycle
e.g. by resting on the seat or loading the
rear rack when your hands or tools are
close to the suspension element. Your
hands may get caught and squeezed when
the suspension compresses.
For the rear suspension a spring element is
combined with a hydraulic damping unit in a
suspension element. The damping results from
fluid friction of oil flowing through thin holes
of a valve in between two chambers inside the
damper. A slightly noticeable sound that may
occur from this oil flow is normal. Due to the
fluid friction the spring element may heat up,
therefore touch the spring element after a
ride only very carefully.
Danger!
The suspension ele-
ments are filled with gas under high pres-
sure. Never try to open the damper or to
remove the screw at the gas tank. Inside
the damper there are no user serviceable
parts. In case of damage you will have to
take the complete suspension element to
your dealer.
The tricycle comes standard with a steel
spring rear shock. As an option you can get
the air shock R

Monarch that uses
air as spring medium.
For a maximum of riding comfort the system
should use about 30% of its travel while you
sit on the tricycle in driving position. ("sag").

Adjustment
The preload determines how far the suspen-
sion compresses when you are sitting on the
tricycle while standing still.
Therefore it is necessary that you have the
correct spring stiffness according to your
weight. (On page 69 you will find more infor-
mation about changing the springs).
Measure the distance between the two sus-
pension element bolts or between rear rack
and rear wheel while the tricycle is unloaded
as well as while sitting on the tricycle in riding
position. Also take into account possible lug-
gage. Find out the total suspension travel pos-
sible for your tricycle with the method
described above, depending on the mounted
add-on-parts and clips on the piston rod. The
static compression should amount to about
one third of the overall suspension travel.
You can affect this negative suspension travel
depending on how much you weigh and how
much you load your tricycle either by adjust-
ing the suspension pre-load for fine tuning or
by replacing the spring with a spring with a
different stiffness in the rough tuning.
In order to adjust the suspension pre-load
turn the adjustment ring on the threaded part
of the suspension element by hand. Turning
the adjustment ring clockwise (looking at it
from behind) reduces the preload, turning it
counter clockwise you screw the adjustment
ring towards the spring and increase the sus-
pension pre-load. It is helpful to turn the
spring together with the adjustment ring.
