Safety information
EAU1028C
Be a Responsible Owner
As the vehicle’s owner, you are respon-
sible for the safe and proper operation
of your motorcycle.
Motorcycles are single-track vehicles.
Their safe use and operation are de-
pendent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements before
riding this motorcycle.
He or she should:
Obtain thorough instructions from
a competent source on all aspects
of motorcycle operation.

Observe the warnings and mainte-
nance requirements in this Own-
er’s Manual.

Obtain qualified training in safe
and proper riding techniques.

Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and/or when made neces-
sary by mechanical conditions.

Never operate a motorcycle with-
out proper training or instruction. Take a training course. Beginners
should receive training from a cer-
tified instructor. Contact an autho-
rized motorcycle dealer to find out
about the training courses nearest
you.
Safe Riding
Perform the pre-operation checks each
time you use the vehicle to make sure it
is in safe operating condition. Failure to
inspect or maintain the vehicle properly
increases the possibility of an accident
or equipment damage. See page 5-1
for a list of pre-operation checks.

This motorcycle is designed to car-
ry the operator and a passenger.

The failure of motorists to detect
and recognize motorcycles in traf-
fic is the predominating cause of
automobile/motorcycle accidents.
Many accidents have been caused
by an automobile driver who did
not see the motorcycle. Making
yourself conspicuous appears to
be very effective in reducing the
chance of this type of accident.
Therefore:
Wear a brightly colored jacket. Use extra caution when you are
approaching and passing
through intersections, since in-
tersections are the most likely
places for motorcycle accidents
to occur.
Ride where other motorists can see you. Avoid riding in another
motorist’s blind spot.
Never maintain a motorcycle without proper knowledge. Con-
tact an authorized motorcycle
dealer to inform you on basic
motorcycle maintenance. Cer-
tain maintenance can only be
carried out by certified staff.

Many accidents involve inexperi-
enced operators. In fact, many op-
erators who have been involved in
accidents do not even have a cur-
rent motorcycle license.
Make sure that you are qualifiedand that you only lend your mo-
torcycle to other qualified opera-
tors.
Know your skills and limits. Staying within your limits may
help you to avoid an accident.
We recommend that you prac-

D-mode (drive mode)D-mode is an electronically controlled
engine performance system. This mod-
el has three mode selections: “STD”,
“A”, and “B”.
WARNING
EWA18440
Do not change the drive mode whilethe vehicle is moving.
With the throttle grip closed, push this
switch to change the drive mode in the
following order:
STD  A  B  STDTIP
Make sure you understand each
drive mode before operating the drive mode switch.

The current drive mode is shown in
the drive mode display (page
4-10).

The current drive mode is savedwhen the vehicle is turned off.
Mode “STD”
Mode “STD” is suitable for various rid-
ing conditions.
This mode allows the rider to enjoy
smooth and sporty drivability from the
low-speed range to the high-speed
range.
Mode “A”
Mode “A” offers a sportier engine re-
sponse in the low- to mid-speed range
compared to mode “STD”.
Mode “B”
Mode “B” offers response that is some-
what less sharp compared to mode
“STD” for riding situations that require
especially sensitive throttle operation.
EAU76434
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.

Setting the traction control system
With the throttle closed, push this
switch down to change from TCS “1” to
TCS “2”. Push up to change from “2” to
“1”.
With the vehicle stopped, push this
switch up for two seconds to turn the
system off. Push down to turn the sys-
tem on.
TIP
The current TCS setting is shown
in the TCS display (page 4-10).

Traction control can be turned on
or off only when the vehicle is
stopped.

When the key is turned to “ON”,
traction control is turned on and set to “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.
TCS “OFF”
TCS “OFF” turns the traction control
system off.
TCS “1”
TCS “1” minimizes traction control as-
sist.
TCS “2”
TCS “2” maximizes traction control as-
sist; wheel spin is most strongly con-
trolled. 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.
When the traction control system has
been set to “OFF”, the “ ” indicator
light will come on.
NOTICE
ECA16801
Use only the specified tires. (See
page 7-17.) Using different sized
tires will prevent the traction control
system from controlling tire rotationaccurately.

12 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 the key back to “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.
EAU76401
Quick shift systemThe quick shift system (QS) allows for
full-throttle, clutch lever-less, electroni-
cally-assisted upshifts. When the shift
switch detects motion in the shift pedal
(page 4-14), engine power and drive
torque are momentarily adjusted to al-
low the upshift to occur.TIP
The quick shift system operates
when traveling at least 20 km/h (12
mi/h) with an engine speed of 2300
r/min or higher, and only when ac-
celerating.

It does not operate when the clutchlever is pulled.
