Front suspension elements

Handling instructions
Danger!
The mounted spring is
under tension. Do not remove the preload
adjuster when adjusting the spring preload.
Make sure the adjusting disc's thread is
fully screwed into the stanchion tube. Oth-
erwise it may become loose and hurt you.
The damping rate can be altered by exchang-
ing the elastomer bands inside the suspension
struts, see “Removing and disassembling the
suspension struts” on page 77.
Customizing the front suspension
The front suspension can be customized by
different measures:
•
- adjusting the preload (see page 22)
•
- exchanging the elastomers or spacers
•
- exchanging the steel springs
•
- exchanging the stabilizer bar
•
- exchanging the damping elastomer bands
According to your order, the tricycle 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
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).
