Instrument and control functions
(the LCS icon will not appear and the
launch control function cannot be acti-
vated).
When LCS has been set to level 1 or 2
for the selected YRC mode, the LCS
indicator on the main screen will ap-
pear in a grey color to indicate that
LCS is available. When the launch con-
trol system has been activated (made
ready for use via the mode switch), the
5
LCS indicator will turn white.
TIP
LCS works in conjunction with the LIF
system. LCS cannot be used if LIF is
turned off.
Quick shifter
The quick shifter is divided into QS
(upshift) and QS
tions. QS and QS
and can be independently turned on or
off.
QS can be set to 1, 2, or OFF. Set-
ting level 1 is designed for maximum
acceleration, while setting level 2 is de-
signed to give smooth shifts at halfway
or less throttle openings. OFF turns the
respective upshift or downshift func-
tion off, and the clutch lever must then
be used when shifting in that direction.
TIP
 Set QS

 Set QS
around town-riding.
LIF
LIF can be set to 1, 2, 3, or OFF. Set-
ting level 3 most strongly reduces
wheel lift, and setting level 1 provides
the least amount of system interven-
tion. OFF turns LIF off and LCS will be
disabled for the selected YRC mode.

EBM
This system has three settings. Level 1
provides the least amount of engine
brake management intervention, and
therefore the strongest amount of en-
to 1 for track or sporty
gine braking. Level 3 provides the
greatest amount of engine brake man-
to 2 for touring or
agement intervention, and therefore
the least amount of engine braking.
BC
Select BC1 when only standard ABS is
desired. Select BC2 to have the brake
control system regulate brake pressure
while cornering to suppress lateral
wheel slip.
