Handling instructions
Customizing the front suspension
The front suspension can be customized by
different measures:
x - adjusting the preload (see page 22)
x - exchanging the elastomers or spacers
x - exchanging the steel springs
x - exchanging the stabilizer bar
x - 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:
x - steel spring soft (red)
x - 4 MCU elastomers 30 mm
x - 1 spacer 30 mm
x - stabilizer bar soft (white)
x - low damping rate (elastomer bands 1,6
mm)
Standard suspension setup above 90 kg:
x - steel spring hard (yellow)
x - 4 MCU elastomers 30 mm
x - 1 spacer 30 mm
x - stabilizer bar hard (grey)
x - low damping rate (elastomer bands 1,6
mm)
Enclosed for individual setup:
x - 2 MCU elastomers 30 mm
x - 2 spacers 30 mm
x - 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
suspension travel forms a straight line. Force
and travel are related to each other by a con-
stant factor, called spring rate, throughout the
whole suspension travel. This is a typical char-
acteristic of steel springs.
The characteristic is referred to as progres-
sive (or rising rate) when the spring rate in-
creases with suspension travel. In the diagram,
this results in a curve with a left bend. Due to
their design, elastomers and air springs show
this characteristic (MCU elastomers show an
almost linear characteristic in the first part of
their travel, see curve nr. 4).
The tuning of 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
