SAFETY INFORMATION
as possible on both sides of the
motorcycle to minimize imbalance
or instability.
l
Shifting weights can create a
sudden imbalance. Make sure that
accessories and cargo are securely
attached to the motorcycle before
riding. Check accessory mounts
and cargo restraints frequently.
l
Never attach any large or heavy
items to the handlebar, front fork,
or front fender. These items,
including such cargo as sleeping
bags, duffel bags, or tents, can
create unstable handling or a slow
steering response.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this motorcycle. Since Yamaha cannot
test all other accessories that may be
available, you must personally be
responsible for the proper selection,
installation and use of non-Yamaha
accessories. Use extreme caution when
selecting and installing any accessories.
Keep the following guidelines in mind,
as well as those provided under“Loading” when mounting accessories.
l
Never install accessories or carry
cargo that would impair the
performance of your motorcycle.
Carefully inspect the accessory
before using it to make sure that it
does not in any way reduce ground
clearance or cornering clearance,
limit suspension travel, steering
travel or control operation, or
obscure lights or reflectors.lAccessories fitted to the
handlebar or the front fork area
can create instability due to
improper weight distribution or
aerodynamic changes. If
accessories are added to the
handlebar or front fork area, they
must be as lightweight as
possible and should be kept to a
minimum.lBulky or large accessories may
seriously affect the stability of the
motorcycle due to aerodynamic
effects. Wind may attempt to lift
the motorcycle, or the motorcycle
may become unstable in cross
winds. These accessories may
also cause instability whenpassing or being passed by large
vehicles.
lCertain accessories can displace
the operator from his or her
normal riding position. This
improper position limits the
freedom of movement of the
operator and may limit control
ability, therefore, such
accessories are not
recommended.
l
Use caution when adding electrical
accessories. If electrical
accessories exceed the capacity of
the motorcycle’s electrical system,
an electric failure could result,
which could cause a dangerous
loss of lights or engine power.
Gasoline and exhaust gas
l
GASOLINE IS HIGHLY
FLAMMABLE:lAlways turn the engine off when
refueling.lTake care not to spill any gasoline
on the engine or exhaust system
when refueling.lNever refuel while smoking or in
the vicinity of an open flame.

EAU15301
SidestandThe sidestand is located on the left side
of the frame. Raise the sidestand or lower
it with your foot while holding the
motorcycle upright.The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation of
the ignition circuit cut-off system.)
EWA10240
The vehicle must not be ridden with
the sidestand down, or if the
sidestand cannot be properly moved
up (or does not stay up), otherwise
the sidestand could contact the
ground and distract the operator,
resulting in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the
responsibility of raising the sidestand
before starting off. Therefore, check
this system regularly as described

PRE-OPERATION CHECKS
EAU15592
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposur\
e to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspection,
to check the following points before each ride.Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very short
time; and the added safety it assures is more than worth the time involved.
EWA11150
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operating
the vehicle.

EAU26001
CareWhile 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 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 cleaning1. 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 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
ECA10770
l
l l
l
l
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
affected area any longer than
instructed. Also, thoroughly
rinse the area off with water,
immediately dry it, and then
apply a corrosion protection
spray.
l
l l
l
l
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.
l
l l
l
l
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
removers or inhibitors, brake
fluid, antifreeze or electrolyte.
l
l l
l
l
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 bearings, fork
and brakes), electric
components (couplers,
connectors, instruments,
switches and lights), breather
hoses and vents.
l
l l
l
l
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 may
leave scratches on the
windshield. 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.
