EquipmentWhen you ordered your BMW
motorcycle, you chose various
items of custom equipment. This
Rider's Manual describes option-
al extras (OE) offered by BMW
and selected optional accessor-
ies (OA). This explains why the
manual may also contain de-
scriptions of equipment which
you have not ordered. Please
note, too, that your motorcycle
might not be exactly as illus-
trated in this manual on account
of country-specific differences.
If your BMW was supplied with
equipment not described in
this Rider's Manual, you will
find these features described in
separate manuals.
Technical dataAll dimensions, weights and
power ratings stated in the
Rider's Manual are quoted to the
standards and comply with the
tolerance requirements of the
Deutsche Institut für Normung
e.V. Versions for individual
countries may differ.CurrencyThe high safety and quality
standards of BMW motorcycles
are maintained by constant
development work on designs,
equipment and accessories.
Because of this, your motorcycle
may differ from the information
supplied in the Rider's Manual.
Nor can BMW Motorrad entirely
rule out errors and omissions.
We hope you will appreciate that
no claims can be entertained on
the basis of the data, illustrations
or descriptions in this manual.
17zGeneral instructions

shocks transmitted by the wheel
to the suspension.
Spring preload of the Air Damp-
ing System is adjusted to suit
total weight (motorcycle plus
rider, plus luggage) by changing
the air pressure in this system.
You can use the valve on the Air
Damping System to reduce pres-
sure, or you can increase pres-
sure by connecting the pump to
this valve.Fore-and-aft tilt indicatorThe fore-and aft tilt indicator on
the motorcycle has much the
same function as a spirit level,
and indeed it is very similar in ap-
pearance to an ordinary bubble
level. The air-pressure setting is
ideal when the fore-and-aft tilt
indicator shows that the motor-
cycle carrying rider and load is
horizontal.
Always check the air pressure
before riding off.
Adjusting air pressureIt is essential to set the pressure
in the Air Damping System to
suit the load carried on the mo-
torcycle. Increase air pressure
when the motorcycle is heavily
loaded and reduce air pressure
accordingly when the motorcycle
is lightly loaded.
You read the fore-and-aft tilt in-
dicator by sitting on the seat in
such a way that you can keep
the motorcycle balanced with
your feet, but the motorcycle
is supporting as much of your
weight as possible.
BMW Motorrad recommends
setting the air pressure in the Air
Damping System marginally high-
er than would be necessary for
the weight of the rider plus the
expected weight of the load. You
can then reduce the air pressure
while sitting on the motorcycle.
Air pressure and
temperatureWhen the Air Damping System is
working hard to absorb shocks,
the air inside the system be-
comes warmer. This causes the
air to expand with the result that
ride height increases, a welcome
effect for off-roading. In order
to ensure that air pressure is set
correctly, you must always check
and adjust the air pressure when
the Air Damping System is cold,
in other words not immediately
after the motorcycle has been
used for off-roading.
If extreme loads are imposed on
the system the increase in tem-
perature can be severe, and un-
der these conditions the effects
of the increase in ride height can
be perceived as uncomfortable.
Under these exceptional circum-
stances it is a good idea to let
air out of the system, using the
level gauge to correct the motor-

cycle's fore-and-aft tilt ( 35).
Remember to readjust accord-
ingly once the system has cooled
down again.Lengthy periods of disuseIf it is going to be out of use for
more than two months, support
the motorcycle in such a way
that the wheels are not taking
any weight, for example by lifting
it BMW Motorrad auxiliary stand.
Check the air pressures before
removing the motorcycle from
the auxiliary stand. You can use
the pressure gauge on the pneu-
matic pump for this check.Adjusting air pressure in

436zOperation

Turn pneumatic-pump hose3
toward the pneumatic pump
and close velcro fastener2.
Sit on the motorcycle, hold it
upright and allow as much of
your weight as possible to rest
on the motorcycle.
Push in the valve pin, allow air
to escape from the Air Damp-
ing System and check the
level.
You can use the point of
the valve cap to push in the
valve pin.Continue to allow air to escape
until the fore-and-aft tilt indicat-
or shows horizontal.
Screw the valve cap onto the
Air Damping System valve.

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.

HeadlightAdjusting headlight for
driving on right/driving on
leftThe motorcycle's headlight beam
is symmetric, so there is no need
for modification if you intend rid-
ing in a country where the op-
posite rule of the road applies.
Beam throw and air
pressure in the Air
Damping SystemHeadlight beam throw is kept
constant when the air pressure
in the Air Damping System is
adjusted to suit load.
Air-pressure adjustment might
not suffice only if the motorcycle
is very heavily loaded. Under
these circumstances, headlight
beam throw has to be adjusted
to suit the weight carried by the
motorcycle.
Consult a specialist work-
shop, preferably an au-
thorised BMW Motorrad deal-
er, if you are unsure whether
the headlight basic setting is
correct.Screws1on left and right al-
low the height of the headlight

should be carried out by a spe-
cialist workshop, preferably an
authorised BMW Motorrad deal-
er.

Safety instructionsRider's equipmentDo not ride without the correct
clothing. Always wear:
Helmet
Motorcycling jacket and
trousers
Gloves
Boots
This applies even to short jour-
neys, and to every season of the
year. Your authorised BMW Mo-
torrad dealer will be glad to ad-
vise you on the correct clothing
for every purpose.SpeedIf you ride at high speed, always
bear in mind that various bound-
ary conditions can adversely af-
fect the handling of your motor-
cycle:Settings of the spring-strut and
shock-absorber system
Imbalanced load
Loose clothing
Insufficient tyre pressure
Poor tyre tread
Etc.
Correct loading
Overloading and imbal-
anced loads can adversely
affect the motorcycle's handling.
Do not exceed the permissible
gross weight and be sure to
comply with the instructions on
loading.
Alcohol and drugs
Even small amounts of
alcohol or drugs will ad-
versely affect your perception
and your ability to assess situ-
ations and make decisions, and
slow down your reflexes. Med-
ication can exacerbate these ef-
fects.Do not ride your motorcycle after
consuming alcohol, drugs and/or
medication.
Risk of poisoningExhaust fumes contain carbon
monoxide, which is colourless
and odourless but highly toxic.
Inhaling the exhaust fumes
therefore represents a
health hazard and can even
cause loss of consciousness with
fatal consequences.
Do not inhale exhaust fumes.
Do not run the engine in an en-
closed space.High voltage
Touching live parts of the
ignition system with the
engine running can cause electric
shock.
Do not touch parts of the igni-
tion system when the engine is
running.
544zRiding

Wet brakes
After the motorcycle has
been washed, ridden
through water or ridden in
the rain, the brake discs and
pads might be wet and the
brakes might not take effect
immediately.
Apply the brakes in good time
until the brakes have dried out.
Salt on brakes
The brakes may fail to take
effect immediately if the
motorcycle was ridden on salt-
covered roads and the brakes
were not applied for some time.
Apply the brakes in good time
until the salt layer on the brake
discs and brake pads has been
removed.
Oil or grease on brakes
Oil and grease on the brake
discs and pads considerably
diminish braking efficiency.
Especially after repair and main-
tenance work, make sure that the
brake discs and brake pads are
free of oil and grease.
Dirt or mud on brakes
When riding on loose sur-
faces or muddy roads, the
brakes may fail to take effect
immediately because of dirt or
moisture on the discs or brake
pads.
Apply the brakes in good time
until the brakes have been
cleaned.
The brake pads will wear
more rapidly if you ride fre-
quently on unsurfaced tracks or
poor roads.
Check the thickness of the brakepads more frequently and replace
the brake pads in good time.
Parking your
motorcyclePlacing motorcycle on
side stand
If the ground is soft or un-
even, there is no guaran-
tee that the motorcycle will rest
firmly on the stand.
Always check that the ground
under the stand is level and
firm.
Switch off the engine.
Pull the handbrake lever.
Hold the motorcycle upright
and balanced.
Use your left foot to extend the
side stand fully.
The side stand is designed
to support only the weight
of the motorcycle.
Do not lean or sit on the
