Adjusting mirror armSlacken nut1.
Turn the mirror arm to the ap-
propriate position.
Tighten the nut to the spe-
cified tightening torque, while
holding the mirror arm to en-
sure that it does not move out
of position.

Spring preloadAdjustment for rear
suspensionIt is essential to set spring pre-
load of the rear suspension to
suit the load carried by the mo-
torcycle. Increase spring preload
when the motorcycle is heavily
loaded and reduce spring preload
accordingly when the motorcycle
is lightly loaded.Adjusting spring preload
for rear wheelMake sure the ground is level
and firm and place the motor-
cycle on its stand. Your motorcycle's hand-
ling will suffer if you do not
match the spring-preload and
damping-characteristic settings.
Adjust the damping characteristic
to suit spring preload.
Adjusting spring preload
while the motorcycle is be-
ing ridden can lead to accidents.
Do not attempt to adjust spring
preload unless the motorcycle is
at a standstill.
Note that there is a danger
of coming into contact with
the hot exhaust silencer when
you turn the knob.
434zOperation

Allow the silencer to cool.Adjust spring preload by turn-
ing knob 1.
If you want to increase spring
preload, turn the knob toward
HARD.
If you want to reduce spring
preload, turn the knob toward
SOFT.
Basic setting of spring
preload, rear
Turn the knob as far as it
will go in the "SOFT" direc-
tion and then turn it 10 full
turns in the "HARD" direc-
tion. (Full load of fuel, with
rider 85 kg)
DampingAdjustment for front
suspensionYou can fine-tune the suspension
to the road surface by adjusting
both the compression-stage and
rebound-stage damping charac-
teristics of the telescopic forks.
The rebound-stage setting con-
trols the way the suspension re-
acts as it extends, whereas the
compression-stage setting influ-
ences compression of the front
forks under load.
The harder the setting, the more
the movement that the forks can
make to absorb surface irreg-
ularities is damped. When you
choose a soft setting the forks
respond all the more rapidly to
surface irregularities.
Adjusting rebound stage
for front wheelMake sure the ground is level
and firm and place the motor-
cycle on its stand.
You adjust the rebound-stage
characteristic by turning adjust-
ing screw 1.
435zOperation

If you want harder damping,
use a screwdriver to turn the
adjusting screw in the+direc-
tion.
If you want softer damping, use
a screwdriver to turn the ad-
justing screw in the - direction.
Rebound stage, basic
setting, front
Turn adjusting screw as far
as it will go in the "+" dir-
ection, then back it off 11
clicks in the "-" direction.
Adjusting compression
stage for front wheelAdjust the compression stage
by turning adjusting screw 1.
If you want harder damping,
use a screwdriver to turn the adjusting screw in the
+direc-
tion.
If you want softer damping, use
a screwdriver to turn the ad-
justing screw in the - direction.
Compression stage, basic
setting, front
Turn adjusting screw as far
as it will go in the "+" dir-
ection, then back it off 11
clicks in the "-" direction.
Adjustment for rear
suspensionDamping must be adapted to suit
spring preload and the surface on
which the motorcycle is ridden.
An increase in spring preload re-
quires firmer damping, a reduc-
tion in spring preload requires
softer damping.
The harder the setting, the more
the movement that the spring
strut can make to absorb sur-
face irregularities is damped.

NotesThe Maintenance chapter de-
scribes straightforward proced-
ures for checking and replacing
certain wear parts.
Special tightening torques are lis-
ted as applicable. The tightening
torques for the threaded fasten-
ers on your motorcycle are listed
in the section entitled "Technical
data".
You will find information on more
extensive maintenance and re-
pair work in the Repair Manual
on DVD/CD-ROM (RepROM) for
your motorcycle, which is avail-
able from your authorised BMW
Motorrad dealer.
Some of the work calls for spe-
cial tools and a thorough know-
ledge of motorcycles. If you
are in doubt consult a specialist
workshop, preferably your author-
ised BMW Motorrad dealer.
