Care
The exposure of its technology
makes a motorcycle charming but
also vulnerable. Although high-
quality components are used, they
are not all rust-resistant. While a
rusty exhaust pipe may remain
unnoticed on a car, it does look
unattractive on a motorcycle.
Frequent and proper care, howev-
er, will keep your motorcycle look-
ing good, extend its life and main-
tain its performance. Moreover, the
warranty states that the vehicle
must be properly taken care of. For
all these reasons, it is recommend-
ed that you observe the following
cleaning and storing precautions.Before cleaning
1. Cover up the muffler outlet
with a plastic bag.
2. Make sure that all caps and
covers as well as all electrical
couplers and connectors,
including the spark plug cap,
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, sprockets, the
drive chain and wheel axles.
Always rinse the dirt and
degreaser off with water.Cleaning
After normal use
Remove dirt with warm water, a
neutral detergent and a soft clean
sponge, then rinse with plenty of
clean water. Use a tooth or bottle
brush for hard-to-reach parts.
Tougher dirt and insects will come
off more easily if the area is cov-
ered with a wet cloth for a few
minutes before cleaning.

8Avoid using strong acidic
wheel cleaners, especially on
spoked wheels. If you do use
such products for hard-to-
remove dirt, do not leave it on
any longer than instructed,
then thoroughly rinse it off
with water, immediately dry
the area and apply a corrosion
protection spray.

9 8Improper 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 plastic.
8Do 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 abra-
sive cleaning products, solvent
or thinner, fuel (gasoline), rust
removers or inhibitors, brake
fluid, antifreeze or electrolyte.8Do not use high-pressure
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the
following areas: seals (of
wheel bearings, swingarm
bearings, forks and brakes),
electric components (couplers,
connectors, instruments,
switches and lights), breather
hoses and vents.
8For motorcycles equipped
with a windshield: Do not use
strong cleaners or hard
sponges as they will cause
dulling or scratching. Some
cleaning compounds for plas-
tic may leave scratches on the
windshield. Test the product
on a small hidden part of the
windshield to make sure they
do not leave any marks. If the
windshield is scratched, use a
quality plastic polishing com-
pound after washing.
After riding in the rain, near the
sea or on salt-sprayed roads
Since sea salt or salt sprayed on
the roads in the winter are
extremely corrosive in combina-
tion with water, carry out the fol-
lowing steps after each ride in the
rain, near the sea or on salt-
sprayed roads. (Salt sprayed in the
winter may remain on the roads
well into spring.)
1. Clean your motorcycle with
cold water and soap after the
engine has cooled down.
ECA00012
cC
Do not use warm water since it
increases the corrosive action of
the salt.
2. Be sure to apply a corrosion
protection spray on all (even
chrome- and nickel-plated)
metal surfaces to prevent cor-
rosion.

97. Check and, if necessary, cor-
rect the tire air pressure, then
raise the motorcycle 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 degraded in one
spot.
8. Cover up the muffler outlet
with a plastic bag to prevent
moisture from entering.
9. Remove the battery and fully
charge it. Store it in a cool, dry
place and recharge it once a
month. Do not store the bat-
tery in an excessively cold or
warm place (less than 0°C or
more than 30°C). For more
information, see “Battery stor-
age” in the chapter “PERIODIC
MAINTENANCE AND MINOR
REPAIRS”.
NOTE:
Make any necessary repairs before
storing the motorcycle.

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