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-

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

If the front of the motor-
cycle is raised too far the
auxiliary stand will lift clear of the
ground and the motorcycle could
topple to one side.
When raising the motorcycle,
make sure that the auxiliary stand
remains on the ground. If ne-
cessary, adjust the height of the
front-wheel stand or the auxiliary
stand.
Apply uniform pressure to push
the front-wheel stand down
and raise the motorcycle.
FusesRemoving fuse
Risk of fire if an attempt is
made to jumper defective
fuse.
Always replace defective fuses
with new fuses of the correct
amperage rating.
Switch off the ignition.

Push latching lever1and open
the fuse cover.
Check the fuse-assignment

circuits checked by a specialist
workshop, preferably an author-
ised BMW Motorrad dealer.
