6 7. While supporting the brake caliper
bracket, pull the wheel axle out,
and then remove the wheel.
ECA00048
CAUTION:_ Do not apply the brake after the
wheel has been removed together
with the brake disc, otherwise the
brake pads will be forced shut. _
EAU04948
To install the rear wheel
1. Install the wheel and the brake cal-
iper bracket by inserting the wheel
axle from the left-hand side.NOTE:_

Be sure to insert the retainer on
the brake caliper bracket into the
slot in the swingarm.


Make sure that there is enough
space between the brake pads be-
fore installing the wheel.
_
2. Install the drive chain onto the rear
sprocket, and then adjust the drive
chain slack. (See page 6-33 for
drive chain slack adjustment pro-
cedures.)
3. Install the axle nut, and then lower
the rear wheel so that it is on the
ground.
4. Tighten the axle nut to the speci-
fied torque.

7-MOTORCYCLE CARE AND STORAGECare While the open design of a motorcycle
reveals the attractiveness of the tech-
nology, it also makes it more vulnera-
ble. Rust and corrosion can develop
even if high-quality components are
used. A rusty exhaust pipe may go un-
noticed on a car, however, it detracts
from the overall appearance 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 performance.Before cleaning
1. Cover the muffler outlet with a
plastic bag after the engine has
cooled down.
2. Make sure that all caps and covers
as well as all electrical couplers
and connectors, including the
spark plug caps, are tightly in-
stalled.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod-
ucts onto seals, gaskets, sprock-
ets, the drive chain and wheel
axles. Always rinse the dirt and
degreaser off with water.Cleaning
ECA00010
CAUTION:_

Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If such products are
used on hard-to-remove dirt, do
not leave the cleaner on the af-
fected area any longer than in-
structed. Also, thoroughly rinse
the area off with water, immedi-
ately dry it, and then apply a
corrosion protection spray.


Improper 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.

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
washers or steam-jet cleaners
since they cause water seep-
age and deterioration in the fol-
lowing areas: seals (of wheel
and swingarm bearings, fork
and brakes), electric compo-
nents (couplers, connectors,
instruments, switches and
lights), breather hoses and
vents.


For motorcycles equipped with
a windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning
compounds for plastic mayleave scratches on the wind-
shield. Test the product on a
small hidden part of the wind-
shield to make sure that it does
not leave any marks. If the wind-
shield is scratched, use a quali-
ty plastic polishing compound
after washing.
_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. Use the
special sponge, which is included in the
plastic bag containing the owner’s
manual, to clean the muffler and to re-
move any discoloration from it.After riding in the rain, near the sea or
on salt-sprayed roadsSince 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.NOTE:_ 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.
ECA00012
CAUTION:_ Do not use warm water since it in-
creases the corrosive action of the
salt. _2. After drying the motorcycle, apply
a corrosion protection spray on all
metal, including chrome- and nick-
el-plated, surfaces to prevent cor-
rosion.

Storage Short-term
Always store your motorcycle in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA00014
CAUTION:_

Storing the motorcycle in a
poorly ventilated room or cover-
ing it with a tarp, while it is still
wet, will allow water and humid-
ity to seep in and cause rust.


To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
_
Long-term
Before storing your motorcycle for
several months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
3. Perform the following steps to pro-
tect the cylinders, piston rings, etc.
from corrosion.
a. Remove the spark plug caps
and spark plugs.
b. Pour a teaspoonful of engine
oil into each spark plug bore.
c. Install the spark plug caps onto
the spark plugs, and then place
the spark plugs on the cylinder
head so that the electrodes are
grounded. (This will limit spark-
ing during the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder walls with oil.)e. Remove the spark plug caps
from the spark plugs, and then
install the spark plugs and the
spark plug caps.
EWA00003
WARNING
_ To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turning
the engine over. _4. Lubricate all control cables and
the pivoting points of all levers and
pedals as well as of the sidestand/
centerstand.
5. Check and, if necessary, correct
the tire air pressure, and then lift
the motorcycle so that both of its
wheels are off the ground. Alterna-
tively, turn the wheels a little every
month in order to prevent the tires
from becoming degraded in one
spot.
