SAFETY INFORMATION
• Certain accessories can dis-
place 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 acces-
sories are not recommended.
●Use caution when adding electri-
cal accessories. If electrical ac-
cessories exceed the capacity of
the motorcycle's electrical sys-
tem, an electric failure could re-
sult, which could cause a danger-
ous loss of lights or engine power.
Gasoline and exhaust gas
●GASOLINE IS HIGHLY FLAM-
MABLE:
• Always turn the engine off
when refueling.
• Take care not to spill any gaso-
line on the engine or exhaust
system when refueling.
• Never refuel while smoking or
in the vicinity of an open flame.
●Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi-
sonous and may cause loss of
consciousness and death within a
short time. Always operate your
motorcycle in an area that has ad-
equate ventilation.
●Always turn the engine off before
leaving the motorcycle unattend-
ed and remove the key from the
main switch. When parking the
motorcycle, note the following:
• The engine and exhaust sys-
tem may be hot, therefore, park
the motorcycle in a place where
pedestrians or children are not
likely to touch these hot areas.
• Do not park the motorcycle on
a slope or soft ground, other-
wise it may fall over.
• Do not park the motorcycle
near a flammable source, (e.g.,
a kerosene heater, or near an
open flame), otherwise it could
catch fire.
●When transporting the motorcycle
in another vehicle, make sure that
it is kept upright. If the motorcycle
should lean over, gasoline may
leak out of the fuel tank.
●If you should swallow any gaso-
line, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediate-
ly. If any gasoline spills on your
skin or clothing, immediately
wash the affected area with soap
and water and change your
clothes.

Immobilizer system
1. Code re-registering key (red bow)
2. Standard keys (black bow)
This vehicle is equipped with an im-
mobilizer system to help prevent theft
by re-registering codes in the standard
keys. This system consists of the fol-
lowing.
●a code re-registering key (with a
red bow)
●two standard keys (with a black
bow) that can be re-registered
with new codes
●a transponder (which is installed
in the code re-registering key)
●an immobilizer unit
●an ECU
●an immobilizer system indicator
light (See page 3-3.)
The key with the red bow is used to reg-
ister codes in each standard key. Since
re-registering is a difficult process, take
the vehicle along with all three keys to a
Yamaha dealer to have them re-regis-
tered. Do not use the key with the red
bow for driving. It should only be used
for re-registering the standard keys. Al-
ways use a standard key for driving.
ECA11820CAUTION:
●DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY
IF IT IS LOST! If the code re-reg-
istering key is lost, registering
new codes in the standard keys
is impossible. The standard keys
can still be used to start the ve-
hicle, however if code re-regis-
tering is required (i.e., if a new
standard key is made or all keys
are lost) the entire immobilizer
system must be replaced.
Therefore, it is highly recom-
mended to use either standardkey and keep the code re-regis-
tering key in a safe place.
●Do not submerse any key in
water.
●Do not expose any key to ex-
cessively high temperatures.
●Do not place any key close to
magnets (this includes, but not
limited to, products such as
speakers, etc.).
●Do not place heavy items on
any key.
●Do not grind any key or alter its
shape.
●Do not disassemble the plastic
part of any key.
●Do not put two keys of any im-
mobilizer system on the same
key ring.
●Keep the standard keys as well
as keys of other immobilizer
systems away from this vehi-
cle's code re-registering key.
●Keep other immobilizer system
keys away from the main
switch as they may cause sig-
nal interference.

NOTE:
Be sure to use the standard key (black
bow) for regular use of the vehicle. To
minimize the risk of losing the code re-
registering key (red bow), keep it in a
safe place and only use it for code re-
registering.

Tachometer
1. Tachometer
2. Red zone
The electric tachometer allows the rid-
er to monitor the engine speed and
keep it within the ideal power range.
ECA10031CAUTION:
Do not operate the engine in the
tachometer red zone.
Red zone: 7,500 r/min and above.
Odometer, tripmeter modes
1. “SELECT” button

Pushing the “SELECT” button switch-
es the display between the odometer
mode “ODO” and the tripmeter modes
“TRIP 1” and “TRIP 2” in the following
order:
ODO
6TRIP 1 6TRIP 2 6ODO
If the fuel level warning light comes on
(see page 3-4), the odometer display
will automatically change to the fuel
reserve tripmeter mode “F-TRIP” and
start counting the distance traveled
from that point. In that case, push the
“SELECT” button to switch the display
between the various tripmeter,
odometer modes in the following or-
der:
F-TRIP

To reset a tripmeter, select it by push-
ing the “SELECT” button, and then
push the “RESET” button for at least
four seconds. If you do not reset the
fuel reserve tripmeter manually, it will
reset itself automatically and the dis-
play will return to the prior mode after
refueling and traveling 5 km (3 mi).
