Traction control systemThe traction control system (TCS)
helps maintain traction when accelerat-
ing on slippery surfaces, such as un-
paved or wet roads. If sensors detect
that the rear wheel is starting to slip (un-
controlled spinning), the traction control
system assists by regulating engine
power as needed until traction is re-
stored.
WARNING
EWA15433
The traction control system is not a
substitute for riding appropriately
for the conditions. Traction control
cannot prevent loss of traction due
to excessive speed when entering
turns, when accelerating hard at a
sharp lean angle, or while braking,
and cannot prevent front wheel slip-
ping. As with any vehicle, approach
surfaces that may be slippery with
caution and avoid especially slip-pery surfaces.
The “ ” indicator light flashes when
traction control has engaged. You may
notice slight changes in engine and ex- haust sounds when the system has en-
gaged.
In certain conditions, the traction con-
trol system may be automatically dis-
abled. Should this happen, the “ ”
indicator light and the “ ” warning
light will come on.
The TCS display (page 3-9) indicates
the current TCS setting. There are
three settings.
TCS “OFF”
TCS “OFF” turns the traction control
system off.
TCS “1”
TCS “1” minimizes traction control sys-
tem assist.
TCS “2”
TCS “2” maximizes traction control as-
sist; wheel spin is most strongly con-
trolled.
TIP
Use the traction control switch
(page 3-14) to change TCS set-
tings.
Traction control can be turned on

stopped.
When the key is turned to “ON”,
traction control is turned on and
set to TCS “1” or “2” (whichever
was last selected).
Turn the traction control system off
to help free the rear wheel if the ve-
hicle gets stuck in mud, sand, orother soft surfaces.
NOTICE
ECA16801
Use only the specified tires. (See
page 6-15.) Using different sized
tires will prevent the traction control
system from controlling tire rotationaccurately.
Resetting the traction control sys-
tem
The traction control system will auto-
matically disable when:
the front wheel or rear wheel
comes off the ground while riding.
excessive rear wheel spin is de-
tected while riding.
either wheel is rotated with the key
turned to “ON” (such as when per- forming maintenance).
If the traction control system is dis-
abled, both the “ ” indicator light and
the “ ” warning light will come on.
Should this occur, try resetting the sys-
tem as follows. 1. Stop the vehicle and turn the key to “OFF”.
2. Wait a few seconds and then turn key back “ON”.
3. The “ ” indicator light should turn off and the system be enabled.
TIPIf the “ ” indicator light remains on af-
ter resetting, the vehicle may still be rid-
den; however, have a Yamaha dealercheck the vehicle as soon as possible.
4. Have a Yamaha dealer check the vehicle and turn off the “ ” warn-
ing light.

the key cannot be removed if the cap isnot properly closed and locked.
WARNING
EWA11092
Make sure that the fuel tank cap is
properly closed after filling fuel.Leaking fuel is a fire hazard.
EAU13222
FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, followthese instructions. 1. Before refueling, turn off the en- gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters and
clothes dryers.
2. Do not overfill the fuel tank. When refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine or
the sun can cause fuel to spill out
of the fuel tank. 3. Wipe up any spilled fuel immedi-
ately. NOTICE: Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plastic
parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swallow

NOTICE
ECA11401
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,as well as to the exhaust system.
TIP
This mark identifies the recom-
mended fuel for this vehicle as
specified by European regulation
(EN228).
Check that gasoline nozzle has thesame identifier when fueling.
Your Yamaha engine has been de-
signed to use premium unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different
brand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
Gasohol
There are two types of gasohol: gaso- hol containing ethanol and that contain-
ing methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.
Recommended fuel:
Premium unleaded gasoline (Gaso-
hol [E10] acceptable)
Fuel tank capacity: 14 L (3.7 US gal, 3.1 Imp.gal)
Fuel reserve amount:
2.6 L (0.69 US gal, 0.57 Imp.gal)

check each hose connection.
check each hose for damage. Re-
place if necessary.
confirm the end of each hose is not
blocked. Clean if necessary.
confirm that each hose is routed

Catalytic converterThis model is equipped with a catalytic
converter in the exhaust system.
WARNING
EWA10863
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns:
Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
Make sure that the exhaust sys-
tem has cooled down before do-
ing any maintenance work.
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up ofheat.
NOTICE
ECA10702
Use only unleaded gasoline. The use
of leaded gasoline will cause unre- pairable damage to the catalytic
converter.

Adjusting the front fork
WARNING
EWA14671
Always adjust the spring preload on
both fork legs equally, otherwise
poor handling and loss of stabilitymay result.
Each front fork leg is equipped with a
spring preload adjusting bolt. The right
front fork leg is equipped with a re-
bound damping force adjusting screw.NOTICE
ECA10102
To avoid damaging the mechanism,
do not attempt to turn beyond themaximum or minimum settings.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt on each fork leg in di-
rection (a). To decrease the spring pre-
load and thereby soften the
suspension, turn the adjusting bolt on
each fork leg in direction (b). The spring preload setting is deter-
mined by measuring distance A, shown
in the illustration. The shorter distance
A is, the higher the spring preload; the
longer distance A is, the lower the
spring preload.

12 Rebound damping force
The rebound damping force is adjusted
on the right front fork leg only.
To increase the rebound damping force
and thereby harden the rebound damp-
ing, turn the adjusting screw in direction
(a). To decrease the rebound damping
force and thereby soften the rebound
damping, turn the adjusting screw in di-
rection (b).
TIP
Although the total number of clicks
of a damping force adjusting
mechanism may not exactly match
the above specifications due to
small differences in production, the
actual number of clicks always
represents the entire adjusting
range. To obtain a precise adjust-
ment, check the number of clicks
of each damping force adjusting
mechanism and to modify the
specifications as necessary.
When turning a damping force ad-
juster in direction (a), the 0 click
position and the 1 click positionmay be the same.
