Adjusting the rear suspension ele-
ment
For the rear suspension of the Street Machine
GT a steel spring is combined with a hydraulic
damping unit in a spring element.The damping
results from fluid friction of an oil flow
through thin holes of a throttle valve in bet-
ween 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 very ca-
refully.
Adjusting the suspension
Danger! While adjusting the rear suspen-
sion element never load the bicycle e.g.
through resting on the seat or loading the
rear rack when your hands or tools are clo-
se to the suspension element. Otherwise
your hands may get caught and squeezed
when the suspension compresses.
The suspension travel is adjusted by adding clips to the piston
rod of the spring element.
Danger! Take care that the rear wheel or
mudguard never hits frame, rear rack or lug-
gage box while the suspension is fully com-
pressed.
Therefore relax the spring completely by
turning the spring retention disc on the
thread of the spring element as far as it will
go (before this, push the possibly existing sa-
fety spring ring from its slot in the threaded
section as far as it will go). Have a second
person mount the bicycle and make the sus-
pension bottom out by leaning on the seat
or the rear rack.
If the distance between the wheel or mud-
guard and the frame or rear rack is smaller
than 1 cm you will have to mount an addi-
tional spacer. In case you don't, the mud-
guard may break suddenly or the rear wheel
might be blocked which can lead to serious
crashes.
Danger! The suspension elements are filled
with gas under high pressure. 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 suspen-
sion element to your dealer.
