Purpose of the adjustment of the
suspension
Your Street Machine GT is fitted with a sus-
pension fork for the front wheel and a rear
swing arm for the suspension of the rear
wheel.This system compensates small bumps
on the road so that riding is comfortable and
the strain on your bicycle is reduced.
A well-adjusted suspension improves the trac-
tion of your bicycle. Especially in bends this
does not only allow a higher speed but it also
increases your safety.
In order to achieve maximum riding comfort,
the suspension settings have to match your
weight as well as the road condition.
The goals of the adjustment are:
maximum use of the available suspension
travel without the suspension frequently
bottoming out
quick reaction of the suspension without
obvious oscillation after having passed
a bump
avoiding self inforcing oscillations, that means
increasing oscillations of the suspension
system due to pedaling influence, rhythmic
body movements or permanent wavy
underground
Suspension and damping
The suspension systems of the suspension fork
and the rear swing arm are fitted with the ac-
tual springs and dampers, which are mounted
separately.
Often, the terms suspension and damping are
used inappropriately in everyday language.
The spring is the elastic element that com-
presses and decompresses through the load,
which occurs on bumpy roads.While decom-
pressing the spring releases the same energy it
has saved during compression.
The Street Machine GT is fitted with coil
springs of steel at the suspension fork and the
rear fork swing arm. In addition to this the
suspension fork contains springs made of mi-
crocellular foam elastomers. (MCU).
The damper slows down the process of com-
pression and decompression.That means that
the bicycle after having passed a bump does
not immediately "spring" back to the initial po-
sition or even further than that.The damper
converts spring energy into friction and finally
into heat, and thus takes away energy from the
suspension system.That way the damper pre-
vents that the spring swings uncontrolled after
an initial stimulation. In addition the damper
helps to avoid self inforcing oscillations of the
suspension that may be caused by reoccurring
stimulation like pedaling forces within a crank
revolution or the rhythmic up and down mo-
vement of the legs.
The hydraulic damping of the rear suspension
is adjustable, in case you have mounted the op-
tional suspension element DMM ST8ARC.
