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

sign, otherwise the handling
characteristics of the motorcy-
cle may be different, which
could lead to an accident.

Always make sure that the valve
caps are securely installed to
prevent air pressure leakage.

Use only the tire valves and
valve cores listed below toavoid tire deflation during a ride.
After extensive tests, only the tires list-

WARNING
EWA10601
This motorcycle is fitted with su-
per-high-speed tires. Note the fol-
lowing points in order to make the
most efficient use of these tires.
Use only the specified replace-
ment tires. Other tires may run
the danger of bursting at super
high speeds.

Brand-new tires can have a rela-
tively poor grip on certain road
surfaces until they have been
“broken in”. Therefore, it is ad-
visable before doing any
high-speed riding to ride con-
servatively for approximately
100 km (60 mi) after installing a
new tire.

The tires must be warmed up
before a high-speed run.

Always adjust the tire air pres-
sure according to the operatingconditions.
EAU21963
Cast wheelsTo 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, warpage or oth-
er 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 deformed 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.
