difficult to move, moving it
back and forth will help.
Installing the battery
An overview of the types of
screw used and the corre-
sponding tightening torques can
be found on (
b 125).c
During the work described
below, a motorcycle that
has been parked unsafely can
fall over.
Make sure that the motorcycle is
parked securely.c
• If necessary, ignition key in the
"ignition off" position.
• Place the battery in the battery
compartment, positive termi-
nal on the right in the direction
of travel.• Push the retaining bracket
over the battery; tighten the
screws to the appropriate
tightening torque.
• Fit the positive battery lead first
of all; tighten to the appropri-
ate tightening torque.
• Then fit the negative battery
lead; tighten to the appropriate
tightening torque.
• Fit the battery compartment
lid; tighten the screws to the
appropriate tightening torque.
• Switch on the ignition.
• Fully open the throttle once or
twice.
» The engine management
system records the throttle-
valve position.
After connecting the

Care
Do not use steam jet cleaners
or high-pressure cleaners.cPlasticsClean plastic parts with water
and BMW plastic care
emulsion. This includes in
particular:
– Windscreens
– Headlight lenses made of
plastic
– Covering glass of the
instrument cluster
– Black, unpainted parts
If plastic parts are
cleaned using unsuitable
cleaning agents, the surfaces
can be damaged.
Do not use cleaning agents
that contain alcohol, solvents
or abrasives to clean plastic
parts. "Fly sponges" or spong-
es with hard surfaces can also
lead to scratches.cSoften resilient dirt and
insects by applying a wet
cloth.c
WindscreenRemove dirt and insects with a
soft sponge and lots of water.
Fuel and chemical
solvents attack the
windscreen.
Do not use cleaning agents.cChromeEspecially in the case of road
salt, carefully clean chrome
with plenty of water and BMW
vehicle shampoo. Use chrome
polish for additional treatment.RadiatorClean the radiator regularly to
prevent overheating of the
engine due to inadequate cooling. For example, use a
garden hose with low water
pressure.
Cooling fins can be bent
easily.
When cleaning the radiator,
ensure that the fins are not
bent.c
Paint careRegular washing of the motor-
cycle counteracts the long-
term effects of materials that
damage the paint, especially if
your motorcycle is ridden in
areas with high air pollution or
natural sources of dirt, e.g.
tree resins or pollen.
However, remove particularly
aggressive materials immedi-
ately; otherwise changes in
the paint or discolouration can
occur. These include, e.g.,
spilt fuel, oil, grease, brake
