CARE

While the open design of a motorcycle reveals
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 ap-
pearance of a motorcycle. Frequent and proper
care does not only comply with the terms of the
warranty, but it will also keep your motorcycle
looking good, extend its life and optimize its per-
formance.

Before cleaning

1. Cover the muffler outlet with a plastic bag af-

ter the engine has cooled down.

2. Make sure that all caps and covers as well as

all electrical couplers and connectors, includ-
ing 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

NOTICE

ECA24220

• Avoid using strong acidic wheel cleaners,

especially on spoked wheels. If such prod-

ucts are used on hard-to-remove dirt, do

not leave the cleaner on the affected area

any longer than instructed. Also, thorough-

ly rinse the area off with water, immediately

dry it, and then apply a corrosion protec-

tion spray.

• Improper cleaning can damage plastic

parts (such as cowlings, panels, wind-

shields, headlight lenses, meter lenses,

etc.) and the mufflers. Use only a soft, clean

cloth or sponge with water to clean plastic.

However, if the plastic parts cannot be thor-

oughly cleaned with water, diluted mild de-

tergent with water may be used. Be sure to

rinse off any detergent residue using plenty

of water, as it is harmful to plastic parts.

• 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 fluid, antifreeze

or electrolyte.

• Do not use high-pressure washers or

steam-jet cleaners since they cause water

seepage and deterioration in the following

areas: seals (of wheel and swingarm bear-

ings, fork and brakes), electric components

(couplers, connectors, instruments,

switches and lights), breather hoses and

vents.

• For motorcycles equipped with a wind-

shield: 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 wind-

shield. Test the product on a small hidden

part of the windshield to make sure that it

does not leave any marks. If the windshield

is scratched, use a quality plastic polishing

compound after washing.

After normal use
Remove dirt with warm water, a mild detergent,
and a soft, clean sponge, and then rinse thor-
oughly 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 min-
utes before cleaning.
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 following steps after
each ride in the rain, near the sea or on salt-
sprayed roads.

TIP

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.

NOTICE:

Do not use warm water since it

increases the corrosive action of the salt.

2. Apply a corrosion protection spray on all met-

al, including chrome- and nickel-plated, sur-
faces to prevent corrosion.

After cleaning

1. Dry the motorcycle with a chamois or an ab-

sorbing cloth.
