SPRING PRELOAD
Adjustment
Front spring preload has to
be adjusted to suit the rider's
weight. Increase spring pre-
load for heavier loads, decrease
spring preload for lighter loads.
It is essential to set spring pre-
load of the rear suspension to
suit the load carried by the mo-
torcycle. Increase spring pre-
load when the vehicle is heav-
ily loaded and reduce spring
preload accordingly when the
vehicle is lightly loaded.
Lifting the motorcycle
To adjust the spring preload, an
engine lifter is required; how-
ever this subject will not be
dealt with in detail. If you are
not sure whether this work is
within your capability, contact a
specialist workshop, preferably
an authorised BMW Motorrad
retailer.
Adjusting spring preload for
front wheel
Make sure the ground is level
and firm and place the motor-
cycle on its stand.
Lift the motorcycle with an
engine lifter until there is no
load on the front wheel.
Measure distance D from bot-
tom edge 1 of the slider tube
to front axle 2 .
Remove the engine lifter.
Make sure the ground is level
and firm and place the motor-
cycle on its stand.
Apply the rider's weight to the
motorcycle.
With the assistance of a
second person, measure
the distance D between
the points 1 and 2 again
and calculate the difference
(compression) between the
measured values.
