Customizing the front suspension
The Scorpion fs' front suspension can be
customized by different measures:
- adjusting the preload (see page 21)
- exchanging the elastomers or spacers
- exchanging the steel springs
- exchanging the stabilizer bar
- exchanging the damping elastomer bands
According to your order, the Scorpion fs
comes with standard suspension setup either
up to 90 kg or above 90 kg.
Standard suspension setup up to 90 kg:
- steel spring soft (red)
- 4 MCU elastomers 30 mm
- 1 spacer 30 mm
- stabilizer bar soft (white)
- low damping rate (elastomer bands 1,6 mm)
Standard suspension setup above 90 kg:
- steel spring hard (yellow)
- 4 MCU elastomers 30 mm
- 1 spacer 30 mm
- stabilizer bar hard (grey)
- low damping rate (elastomer bands 1,6 mm)
Enclosed for individual setup:
- 2 MCU elastomers 30 mm
- 2 spacers 30 mm
- 2 elastomer bands 1,7 mm, high damping rate
These standard setups can be customized.As
an example, you can find curves of different
options in the diagram.The curve shape shows
the characteristic of the suspension setup.
The characteristic is referred to as linear when
the curve of suspension force related to sus-
pension travel forms a straight line. Force and
travel are related to each other by a constant
factor, called spring rate, throughout the whole
suspension travel.This is a typical characteristic
of steel springs.
The characteristic is referred to as progressive
(or rising rate) when the spring rate increases
with suspension travel. In the diagram, this re-
sults in a curve with a left bend. Due to their
design, elastomers and air springs show this
characteristic (MCU elastomers show an al-
most linear characteristic in the first part of
their travel, see curve nr. 4).
Tuning your suspension bases on the choice of
the steel spring according to your usual load.
The soft spring moves the area of operation
to low rider and luggage weight, the hard
spring to high rider and luggage weight.The
suspension characteristic is not affected by
choosing another steel spring with different
spring rate.Varying the number of elastomers
and their relation to the number of spacers in-
side the steel spring changes the area of oper-
ation as well as the suspension characteristic.
It is allowed to have one or more blank spaces
out of the five spaces available for elastomers
or spacers. In this case the load during the first
part of the travel is only taken by the steel
spring and the elastomers only affect the sus-
pension after the travel of the blank spaces is
used up.

Caution!
Do not install more than two spa-
cers in one strut, otherwise the full suspen-
sion travel can not be reached. Spacers
should always be installed at the top of the
stack inside the spring to give room for the
screw in the top cap.The setup must be si-
milar in both suspension struts of your trike.
Caution!
The suspension must be set up in
a way that avoids permanent bottoming out
(a clearly recognizable bumping into the end
stops). Permanent bottoming out may redu-
ce the components' life time.
