intervene when the footbrake
7
lever is depressed to apply
the rear brake. Under these
116
circumstances, the rear wheel
can lock up. The function for
detecting the rear wheel's
tendency to lift clear of the
ground is also deactivated.
Risk of rollover, because
the rear wheel lift-off pro-
tection system is switched off.
When braking sharply, be pre-
pared for the rear wheel lifting off
the ground.
Risk of accident, because
ABS on the rear wheel is
z
switched off.
Be prepared during hard breaking
for the rear wheels to lock.
When this mode is selected the
controller of the DTC system
assumes that the motorcycle is
running on racing tyres with max-
imum grip (slicks). Long wheelies
are possible and the same ap-
plies to wheelies at slight angles
of heel, and it is important to
bear in mind that under these
circumstances it is also possible
that the motorcycle might flip
over backwards!
The behaviour of the DDC is the
same as in RACE mode.
Mode changes
A changeover of the functions in
the engine management system
and the ABS and DTC systems
while riding is possible only in
certain operating states:
No drive torque at the rear
wheel
No brake pressure in the brake
system.
In order to achieve this state,
The motorcycle must be at
a standstill with the ignition
switched on
or
The throttle twistgrip must be
in the fully closed position
The brake levers must be in
the released positions
The clutch lever must
be pulled and the clutch
disengaged.
The desired riding mode is ini-
tially preselected. The mode
change does not take place until
the systems in question are all in
the appropriate state.
The selection menu does not
disappear from the display un-
til the mode change has taken
place.
