ever the lift-off detection for the
rear wheel is deactivated. The
rear wheel can lift off the ground!
Flip over risk, as the lift-off
detection for the rear wheel
is deactivated.
Be prepared for lift-off of the
rear wheel in the case of hard
braking.
The DTC system intervenes
even later so that longer drifts
and brief wheelies are also pos-
sible at the end of curves (at an-
gles below 25°).
The DDC setting assumes a
sporty riding style.
SLICK
To activate the SLICK mode, the
coding plug must be used.
SLICK mode was developed for
roads with good visibility and very
high friction coefficients, as they
are usually found on racetracks
only. This mode also assumes
that the motorcycle is riding with
racing tires that have very good
adhesion.
The engine output, increase in
power and response are de-
signed for maximum sportiness.
The response characteristics of
the ABS system in SLICK mode
are derived from the IDM. Fur-
thermore, differently from the
RACE mode, no ABS control
is carried out on actuation of
the footbrake lever on the rear
wheel. The rear wheel can lock
up. The lift-off detection for the
rear wheel is also deactivated.
Flip over risk, as the lift-off
detection for the rear wheel
is deactivated.
Be prepared for lift-off of the
rear wheel in the case of hard
braking.
Risk of injury, as the ABS
control on the rear wheel is
deactivated.
Be prepared for the rear wheel
locking up in the case of
braking.
In this mode the control of the
DTC system assumes that rac-
ing tires with maximum adhesion
(slick tires) are mounted. Longer
wheelies and wheelies at small
angles are also permitted, which
means it is possible to flip over
backward in extreme cases!
The DDC response character-
istics remain identical to those
provided in the RACE mode.
Switchover
The switchover process for the
functions in the engine manage-
ment system, the ABS and the
DTC is only possible in certain
operating modes:
No drive torque at rear wheel
No brake pressure in the brake
system.
To obtain this state,
