RAIN
The increase in torque is linear.
The ABS system always inter-
venes early enough to prevent as
effectively as possible the wheels
from locking and the rear wheel
from lifting off the ground.
The DTC- system intervenes
early enough to prevent the rear
wheel from spinning whenever
possible.
The DDC system is set up for
reserved driving.
SPORT
The behaviour of the ABS is the
same as in RAIN mode.
The DTC system intervenes later
than in RAIN mode, so it is pos-
sible to induce slight drift when
exiting corners.
The behaviour of the DDC is the
same as in RAIN mode.
RACE
RACE is the sportiest mode
available without the coding plug
inserted.
In this mode, the ABS intervenes
later. It still prevents the wheels
from locking, but the function
that detects the tendency of
the rear wheel to lift clear of the
ground is deactivated. The rear
wheel can lift clear of the ground.
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.
The DTC system intervenes
even later than in the other
modes, so lengthy drifts and
wheelies are possible when
exiting corners (at bank angles
less than 25°).
The DDC system is set up for a
sporty riding style.
SLICK
The SLICK mode cannot be ac-
tivated unless the coding plug is
inserted.
The SLICK mode was developed
for situations in which the rider
has an open view of the road
ahead and the surroundings and
is riding on surfaces with the
high level of grip generally en-
countered only on race tracks.
Similarly, the assumption on
which the parameter settings for
this mode are based is that the
motorcycle is fitted with racing
slicks with a very high level of
dry-surface grip.
Engine power, power increase
and throttle response are all set
up for maximum sportiness.
The behaviour of the ABS
system in SLICK mode is derived
from the IDM international
German championship. It
also differs from RACE mode
in that the ABS does not
