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
TIP
Be sure to confirm that the vehicle is completely
cooled.
1. Block or cover the following parts with suit-
able measures.
•
Air duct “1”
(other gaps around shrouds and seats)
•
Muffler outlet “2”
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
ECA26730
• 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.
• 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.
• When cleaning using either a high-pres-
sure cleaning machine or a water hose, do
not direct the water jet toward the following
areas:(Otherwise, it could cause either
damage due to the water pressure or mal-
function due to water entry.)
Wheels or swing arm bearings
Fork seals or brake seals
Electrical parts, such as couplers, switch-
es, battery, etc.
Muffler or hoses
Air cleaner intake port
• Do not clean using a water jet with the seat
or cover removed.
