This traction control system automati-
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.
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 the traction control system
is turned off, SCS, LCS, and LIF
are also turned off automatically.
WARNING
EWA15433
The traction control system is not a
substitute for ri din g appropriately
for the con ditions. Traction control
cannot prevent loss of traction d ue
to excessive spee d when enterin g
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.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.TIPTurn the traction control system off to
help free the rear wheel if the motorcy-
cle gets stuck in mud, sand, or other
soft surfaces.
NOTICE
ECA16801
Use only the specifie d tires. (See
pa ge 7-19.) Usin g different size d
tires will prevent the traction control
system from controllin g tire rotation
accurately.SCS
The slide control system regulates en-
gine power output when a sideward
slide is detected in the rear wheel. It
adjusts power output based on data
from the IMU. This system supports
the traction control system to contrib-
ute to a smoother ride.
EBM
The engine brake management system
reduces engine torque when deceler-
ating. The fuel injection, ignition timing,
and electronic throttle valve are elec-
tronically adjusted by the ECU. There
are 3 settings to suit the track, riding
conditions, or your personal prefer-
ence.

72. To tighten the drive chain, turn thedrive chain slack adjusting bolt on
each side of the swingarm in di-
rection (a). To loosen the drive
chain, turn the adjusting bolt on
each side of the swingarm in di-
rection (b), and then push the rear
wheel forward.
TIPUsing the alignment marks on each
side of the swingarm, make sure that
both drive chain pullers are in the same
position for proper wheel alignment.3. Tighten the axle nut, then the lock-nuts to their specified torques. 4. Make sure that the drive chain
pullers are in the same position,
the drive chain slack is correct,
and the drive chain moves
smoothly.
