MOTORCYCLE CARE AND STORAGE
Care
While the open design of a motorcycle re-
veals the attractiveness of the technology,
it also makes it more vulnerable. Rust and
corrosion can develop even if high-quality
components are used. A rusty exhaust
pipe may go unnoticed on a car, however,
it detracts from the overall appearance of a
motorcycle. Frequent and proper care
does not only comply with the terms of the
warranty, but it will also keep your motor-
cycle looking good, extend its life and opti-
mize its performance.Before cleaning
1. Cover the muffler outlets with plastic
bags after the engine has cooled
down.
2. Make sure that all caps and covers as
well as all electrical couplers and con-
nectors, including the spark plug
caps, are tightly installed.
3. Remove extremely stubborn dirt, like
oil burnt onto the crankcase, with a
degreasing agent and a brush, but
never apply such products onto
seals, gaskets and wheel axles. Al-
ways rinse the dirt and degreaser off
with water.CleaningECA00010
•Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If such products are used
on hard-to-remove dirt, do not
leave the cleaner on the affected
area any longer than instructed.
Also, thoroughly rinse the area off
with water, immediately dry it, and
then apply a corrosion protection
spray.
•Improper cleaning can damage
windshields, cowlings, panels and
other plastic parts. Use only a soft,
clean cloth or sponge with mild
detergent and water to clean plas-
tic.

MOTORCYCLE CARE AND STORAGE
•Do not use any harsh chemical
products on plastic parts. Be sure
to avoid using cloths or sponges
which have been in contact with
strong or abrasive cleaning prod-
ucts, solvent or thinner, fuel (gaso-
line), rust removers or inhibitors,
brake fluid, antifreeze or elec-
trolyte.
•Do not use high-pressure washers
or steam-jet cleaners since they
cause water seepage and deterio-
ration in the following areas: seals
(of wheel and swingarm bearings,
fork and brakes), electric compo-
nents (couplers, connectors,
instruments, switches and lights),
breather hoses and vents.
•For motorcycles equipped with a
windshield: Do not use strong
cleaners or hard sponges as they
will cause dulling or scratching.
Some cleaning compounds for
plastic may leave scratches on the
windshield. Test the product on asmall hidden part of the wind-
shield to make sure that it does
not leave any marks. If the wind-
shield is scratched, use a quality
plastic polishing compound after
washing.
After normal use
Remove dirt with warm water, a mild deter-
gent, and a soft, clean sponge, and then
rinse thoroughly with clean water. Use a
toothbrush or bottlebrush for hard-to-reach
areas. Stubborn dirt and insects will come
off more easily if the area is covered with a
wet cloth for a few minutes before clean-
ing.After riding in the rain, near the sea or on
salt-sprayed roads
Since sea salt or salt sprayed on roads
during winter are extremely corrosive in
combination with water, carry out the fol-
lowing steps after each ride in the rain,
near the sea or on salt-sprayed roads.
NOTE:
Salt sprayed on roads in the winter may
remain well into spring.
1. Clean the motorcycle with cold water
and a mild detergent, after the engine
has cooled down.
ECA00012
Do not use warm water since it increas-
es the corrosive action of the salt.
2. After drying the motorcycle, apply a
corrosion protection spray on all met-
al, including chrome- and nickel-plat-
ed, surfaces to prevent corrosion.

MOTORCYCLE CARE AND STORAGE
6. Lubricate all control cables and the
pivoting points of all levers and ped-
als as well as of the sidestand/center-
stand.
7. Check and, if necessary, correct the
tire air pressure, and then lift the mo-
torcycle so that both of its wheels are
off the ground. Alternatively, turn the
wheels a little every month in order to
prevent the tires from becoming de-
graded in one spot.
8. Cover the muffler outlets with plastic
bags to prevent moisture from enter-
ing them.9. Remove the battery and fully charge
it. Store it in a cool, dry place and
charge it once a month. Do not store
the battery in an excessively cold or
warm place (less than 0 °C or more
than 30 °C). For more information on
storing the battery, see page 6-27.
NOTE:
Make any necessary repairs before stor-
ing the motorcycle.

Be sure to use motor oils that do not contain anti-friction modifiers.
Passenger car motor oils (often labeled “ENERGY CONSERVING II”)
contain anti-friction additives which will cause clutch and/ or starter
clutch slippage, resulting in reduced component life and poor
engine performance.8
