Danger!
The adjustment ring has
always to be screwed on so far that the
spring has no play when unloaded. Other-
wise the adjustment ring could come loose
through shocks while riding and the slotted
rear spring retention disc comes off. In
that case the suspension element may be
damaged or the rear wheel can hit the
frame or rear rack, which may lead to se-
rious falls. Always have an initial preload of
at least half a turn on the spring.
The adjustment ring should be turned not
more than five turns (measured from the
relaxed position) towards the spring. If the
suspension compresses still too far even after
six turns, the spring is too soft and has to be
replaced by a harder spring. A too high pre-
load with a too soft spring will not take ad-
vantage of the full comfort potential.
Danger!
Take care that the rear
wheel or mudguard or suspension element
never hit the frame, seat, rear rack or lug-
gage box while the suspension is fully com-
pressed.
Therefor relax the spring completely by turn-
ing the spring retention disc on the thread of
the spring element as far as possible (before
this, push the possibly existing safety spring
ring from its slot in the threaded section as far
as possible). Have a second person sit down
on the bicycle and make the suspension bot-
tom out by leaning on the seat or the rear
rack.
If the distance between the wheel or mud-
guard and the frame, seat, or rear rack is
smaller than 1 cm you will have to mount an
additional 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.

Changing the steel spring (DV-22)
You can buy the spring for the rear suspen-
sion element in different spring rates at your
dealer.
We recommend the following spring rates,
depending on the overall weight:
Load
Spring stiffness
Grasshopper fx:
•
up to 80 kg: 450 lbs/inch
•
up to 110 kg: 650 lbs/inch
•
up to 140 kg: 850 lbs/inch
•
Streetmachine Gte
•
up to 80 kg: 350 lbs/inch
•
up to 110 kg: 450 lbs/inch
•
up to 140 kg: 550 lbs/inch
•
Speedmachine:
•
up to 80 kg: 450 lbs/inch
•
up to 110 kg: 550 lbs/inch
•
up to 140 kg: 650 lbs/inch
In addition to this, your dealer can also use
springs with other spring rates or special
lightweight springs made of titanium.
In most cases the rate is printed onto the
spring. Pay attention to the correct imprint
since the term "B650" that sometimes occurs
does not necessarily mean 650 lbs./inch!
