Traction control system
The traction control system (TCS)
helps maintain traction when acceler-
ating on slippery surfaces, such as un-
paved or wet roads. If sensors detect
that the rear wheel is starting to slip
(uncontrolled spinning), the traction
control system assists by regulating
engine power as needed until traction
is restored.
WARNING
EWA15433
The traction control system is not a
substitute for rid ing appropriately
for the con ditions. Traction control
cannot prevent loss of traction due
to excessive speed when entering
turns, when acceleratin g har d at a
sharp lean an gle, or while brakin g,
an d cannot prevent front wheel slip-
pin g. As with any vehicle, approach
surfaces that may be slippery with
caution an d avoi d 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.
When the traction control system is
turned off, the “ ” indicator light will
come on.
TIP
 When the vehicle is turned on, the
traction control system is turned
on and set to the last used TCS
setting.
 The current TCS setting is shown
in the TCS display (page 4-12).
TCS settin gs
TCS “OFF”
TCS “OFF” turns the traction control
system off.
TCS “1”
TCS “1” minimizes traction control
system assist.
TCS “2, 3, 4, 5”
TCS levels “2” through “5” sequentially
increase traction control system assist.
TCS “6”
TCS “6” maximizes traction control as-
sist; wheel spin is most strongly con-
trolled.
NOTICE
ECA16801
Use only the specifie d tires. (See
pa ge 7-20.) Usin g different sized
tires will prevent the traction control
system from controllin g tire rotation
accurately.

Settin
g the traction control system
To turn TCS off
Stop the vehicle and:  push up on the TCS switch for two
seconds to turn the traction con-
trol system off.
 push down on the TCS switch to
turn the traction control system
back on.
TIP
Turn the traction control system off to
help free the rear wheel if it is stuck in
mud or sand, etc.
To change TCS settings
Stop the vehicle or close the throttle
and:
 push up on the TCS switch to de-
crease traction control
(6→ 5→ 4→ 3→ 2→ 1).
 push down on the TCS switch to
increase traction control
(1→ 2→ 3→ 4→ 5→ 6).
TIP
TCS settings can also be changed
when moving in straight line if the throt-
tle grip is held in a fixed position for two
seconds while in 4th, 5th, or 6th gear.
WARNING
EWA18940
Take extra precaution when chan g-
in g mo des while ri din g.
Resettin g 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 en-
abled.
TIP
If the “ ” indicator light remains on af-
ter resetting, the vehicle may still be
ridden; however, have a Yamaha deal-
er check the vehicle as soon as possi-
ble.
4. Have a Yamaha dealer check thevehicle and turn off the “ ”
warning light.

Cast wheels
To maximize the performance, durabil-
ity, and safe operation of your vehicle,
note the following points regarding the
specified wheels.
 The wheel rims should be
checked for cracks, bends, warp-
age or other damage before each
ride. If any damage is found, have
a Yamaha dealer replace the
wheel. Do not attempt even the
smallest repair to the wheel. A de-
formed or cracked wheel must be
replaced.
 The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.

Adjustin g the clutch lever free
play
Measure the clutch lever free play as
shown.
Periodically check the clutch lever free
play and, if necessary, adjust it as fol-
lows.
To increase the clutch lever free play,
turn the clutch lever free play adjusting
bolt at the clutch lever in direction (a).
To decrease the clutch lever free play,
turn the adjusting bolt in direction (b).
TIP
If the specified clutch lever free play
cannot be obtained as described
above, proceed as follows.
1. Fully turn the adjusting bolt at the
clutch lever in direction (a) to loos-
en the clutch cable.
2. Remove panel B and cowling C. (See page 7-7.)
