Catalytic converterIf misfiring causes unburned fuel
to enter the catalytic converter,
there is a danger of overheating
and damage.
For this reason, observe the fol-
lowing points:Do not run the fuel tank dry.
Do not attempt to start or run
the engine with a spark-plug
cap disconnected.
Stop the engine immediately if
it misfires.
Use only unleaded fuel.
Comply with all specified main-
tenance intervals.
Unburned fuel will destroy
the catalytic converter.
Note the points listed for protec-
tion of the catalytic converter.
Risk of fireTemperatures at the exhaust are
high.
Flammable materials (e.g.
hay, leaves, grass, clothing
and luggage, etc.) could ignite
if allowed to come into contact
with the hot exhaust pipe.
Do not permit flammable materi-
als to come into contact with the
hot exhaust system.
Cooling would be
inadequate if the engine
were allowed to idle for a lengthy
period with the motorcycle at
a standstill: overheating would
result. In extreme cases, the
motorcycle could catch fire.
Do not allow the engine to idle
unnecessarily. Ride away imme-
diately after starting the engine.
Tampering with the
control unit of the
electronic engine-
management system
Tampering with the engine
control unit can damage
the motorcycle and cause acci-
dents.
Do not tamper with the engine
control unit.
Tampering with the engine
control unit can result in
mechanical loads that the mo-
torcycle's components are not
designed to withstand. Damage
caused in this way is not covered
by the warranty.
Do not tamper with the engine
control unit.

to overheating and shortens the

agents, the surfaces can be dam-
aged.
Do not use cleaning agents that
contain alcohol, solvents or ab-
rasives to clean plastic parts.
Even fly-remover pads or clean-
ing pads with hard surfaces can
produce scratches.Soften stubborn dirt and
insects by covering the af-
fected areas with a wet cloth.ChromeUse plenty of water and BMW
shampoo to clean chrome, par-
ticularly 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 cooling.
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.Paint careWashing the motorcycle regularly
will help counteract the long-term
effects of substances that dam-
age 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, how-
ever, as otherwise the paint can
be affected or become discol-
oured. 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 par-
ticularly easy to see after the
motorcycle has been washed.
Remove stains of this kind im-
mediately, using cleaning-grade
benzene or petroleum spirit on a
clean cloth or ball of cotton wool.
BMW Motorrad recommends
BMW tar remover for removing
specks of tar. Remember to wax
the parts treated in this way.
