area any lon ger than in-
structe d. Also, thorou ghly rinse
the area off with water, imme di-
ately dry it, an d then apply a cor-
rosion protection spray.
 Improper cleanin g can d amage
plastic parts (such as cowlin gs,
panels, win dshield s, hea dlig ht
lenses, meter lenses, etc.) an d
the mufflers. Use only a soft,
clean cloth or spon ge with wa-
ter to clean plastic. However, if
the plastic parts cannot be thor-
ou ghly cleaned with water, di-
lute d mil d d eter gent with water
may be used . Be sure to rinse
off any d etergent resi due usin g
plenty of water, as it is harmful
to plastic parts.
 Do not use any harsh chemical
prod ucts on plastic parts. Be
sure to avoi d using cloths or
spon ges which have been in
contact with stron g or a brasive
cleanin g pro ducts, solvent or
thinner, fuel (g asoline), rust re-
movers or inhi bitors, brake flui d,
antifreeze or electrolyte.
 Do not use hi gh-pressure wash-
ers or steam-jet cleaners since
they cause water seepa ge an d
d eterioration in the followin g ar-
eas: seals (of wheel an d swin g-
arm bearin gs, fork an d b rakes),
electric components (couplers,
connectors, instruments,
switches an d lig hts), breather
hoses an d vents.
 For motorcycles equippe d with
a win dshield : Do not use stron g
cleaners or har d spon ges as
they will cause dullin g or scratching
. Some cleanin g
compoun ds for plastic may
leave scratches on the win d-
shield . Test the pro duct on a
small hi dden part of the win d-
shield to make sure that it d oes
not leave any marks. If the win d-
shield is scratche d, use a quality
plast

ic polishin g compoun d af-
ter washin g.
After normal use
Remove dirt with warm water, a mild
detergent, 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 cleaning.
After riding in the rain or near the sea
Since sea salt is extremely corrosive,
carry out the following steps after each
ride in the rain or near the sea.
1. Clean the motorcycle with cold water and a mild detergent, after
the engine has cooled down.
NOTICE: Do not use warm wa-
ter since it increases the corro-
sive action of the salt.
[ECA10792]
2. Apply a corrosion protection spray on all metal, including chrome-
and nickel-plated, surfaces to pre-
vent corrosion.
After cleaning 1. Dry the motorcycle with a chamois or an absorbing cloth.
2. Immediately dry the drive chain and lubricate it to prevent it from
rusting.

3. Use a chrome polish to shine
chrome, aluminum and stainless-
steel parts, including the exhaust
system. (Even the thermally in-
duced discoloring of stainless-
steel exhaust systems can be re-
moved through polishing.)
4. To prevent corrosion, it is recom- mended to apply a corrosion pro-
tection spray on all metal,
including chrome- and nickel-plat-
ed, surfaces.
5. Use spray oil as a universal clean- er to remove any remaining dirt.
6. Touch up minor paint damage caused by stones, etc.
7. Wax all painted surfaces.
8. Let the motorcycle dry completely before storing or covering it.

For Europe only
The figures quoted are emission levels
and are not necessarily safe working
levels. Whilst there is a correlation be-
tween the emission and exposure lev-
els, this cannot be used reliably to
determine whether or not further pre-
cautions are required. Factors that in-
fluence the actual level of exposure of
work-force include the characteristics
of the work room, the other sources of
noise, etc. i.e. the number of machines
and other adjacent processes, and the
length of time for which an operator is
exposed to the noise. Also the permis-
sible exposure level can vary from
country. This information, however, will
enable the user of the machine to make
a better evaluation of the hazard and
risk.
