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 products, solvent or
thinner, fuel (gasoline), rust re-
movers or inhibitors, brake flu-
id, antifreeze or electrolyte.
●
Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar-
eas: seals (of wheel and swing-
arm bearings, fork and brakes),
electric components (couplers,
connectors, and switches),
breather hoses and vents.
After normal useRemove 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 wa- ter and a mild detergent, after the
engine has cooled down.
NOTICE: Do not use warm water
since it increases the corrosive
action of the salt.
[ECA10791]
2. Apply a corrosion protection spray on all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.
After cleaning 1. Dry the motorcycle with a chamois or an absorbing cloth.
2. Use a chrome polish to shine chrome, aluminum and stainless-
steel parts.
3. To prevent corrosion, it is recom- mended to apply a corrosion pro-
tection spray on all metal,
including chrome- and nickel-plat-
ed, surfaces.
4. Use spray oil as a universal clean- er to remove any remaining dirt. 5. Touch up minor paint damage
caused by stones, etc.
6. Wax all painted surfaces.
7. Let the motorcycle dry completely before storing or covering it.
WARNING
EWA14501
Contaminants on the brakes or tires
can cause loss of control.●
Make sure that there is no oil or
wax on the tires.
●
If necessary, wash the tires with
warm water and a mild deter-
gent. Before riding at higher
speeds, test the motorcycle’s
braking performance and cor-
nering behavior.
NOTICE
ECA10800
●
Apply spray oil and wax spar-
ingly and make sure to wipe off
any excess.
●
Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
