Cleaning easily
damaged componentsPlasticsClean plastic parts with water
and BMW plastic care emul-
sion. This includes in particu-
lar:Windscreen
Headlight lens made of
plastic
Glass cover of the instru-
ment 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.
Even fly-remover pads or
cleaning pads with hard surfaces can produce
scratches.
Soften stubborn dirt and
insects by covering the
affected areas with a wet
cloth.
WindscreenClean off dirt and insects with
a soft sponge and plenty of
water.
Fuel and chemical
solvents attack the
material of the windscreen;
the windscreen becomes
opaque or dull.
Do not use cleaning agents.ChromeUse plenty of water and BMW
shampoo to clean chrome,
particularly if it has been
exposed to road salt. Use
chrome polish for additional
treatment.
RadiatorClean the radiator regularly to
prevent overheating of the en-
gine due to inadequate cool-
ing.
For example, use a garden
hose with low water pressure.
Cooling fins can be bent
easily.
Take care not to bend the fins
when cleaning the radiator.RubberTreat rubber components with
water or BMW rubber-care
products.
Using silicone sprays for
the care of rubber seals
can cause damage.
Do not use silicone sprays
or other care products that
contain silicon.
8135zCare

Paint careWashing the motorcycle
regularly will help counteract
the long-term effects of
substances that damage
the paint, especially if your
motorcycle is ridden in areas
with high air pollution or
natural sources of dirt, for
example tree resin or pollen.
Remove particularly
aggressive substances
immediately, however, as
otherwise the paint can
be affected or become
discoloured. Substances
of this nature include spilt
fuel, oil, grease, brake fluid
and bird droppings. We
recommend BMW vehicle
polish or BMW paint cleaner
for this purpose.
Marks on the paintwork are
particularly easy to see after
the motorcycle has been
washed. Remove stains ofthis kind immediately, using
cleaning-grade benzene or
petroleum spirit on a clean
cloth or ball of cotton wool.
We recommend that specks
of tar be removed with BMW
tar remover. Remember to
wax the parts treated in this
way.
Protective wax
coatingFor the protective wax coating
of paint, we recommend that
you use only BMW vehicle
wax or agents that contain
carnauba wax or synthetic
waxes.
It is time to rewax the paint-
work when water "puddles"
on the surface, instead of
forming beads.
Laying up the
motorcycleClean the motorcycle.
Remove the battery.
Spray the brake and clutch
lever pivots and the main
and side stand pivots with a
suitable lubricant.
Coat bright metal and
chrome-plated parts with
an acid-free grease (e.g.
Vaseline).
Stand the motorcycle in a
dry room in such a way that
there is no load on either
wheel.
Before laying the vehicle
up out of use, have the
engine oil and the oil filter ele-
ment changed by a special-
ist workshop, preferably an
authorised BMW Motorrad
dealer. Combine work for lay-
ing up/restoring to use with a
BMW service or inspection.
