cally adjusts according to the vehicle's
lean angle. To maximize acceleration,
when the vehicle is upright a less
amount of traction control is applied.
When cornering, a greater amount of
traction control is applied.
TCS
TIP

The traction control system may
engage when the vehicle travels
over a bump.

You may notice slight changes in
engine and exhaust sounds when
the traction control or other YRC
systems engage.

When TCS is turned off, SCS,
LCS, and LIF are also turned off
automatically.
WARNING
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 motorcycle, ap-
proach surfaces that
slippery with caution and avoid es-
pecially slippery surfaces.
When the key is turned to "ON", the
traction control system automatically
turns on. The traction control system
can be turned on or off manually only
when the key is in the "ON" position and
the motorcycle is stopped.
TIP
Turn the traction control system off to
help free the rear wheel if the motorcy-
cle gets stuck in mud, sand, or other
soft surfaces.

SPECIAL FEATURES
EWA15432
NOTICE
Use only the specified tires. (See
page 7-18.) Using different sized
tires will prevent the traction control
system from controlling tire rotation
accurately.
SCS
The slide control system regulates en-
gine power output when a sideward
may be
slide is detected in the rear wheel. It ad-
justs power output based on data from
the IMU. This system supports the TCS
to contribute to a smoother ride.
LCS
The launch control system helps the
rider achieve
launches from the starting grid. It
keeps engine speed from rising above
10,000 r/min even when the throttle
grip is fully turned. The LCS regulates
engine power output in conjunction
with the TCS and LIF systems for op-
timal traction and reduced wheel lift.
