Mode changes
A mode change involves func-
tions in the engine management
system, the ABS and the ASC/
DTC and DDC 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 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.

ABS
Partially integral brakes
Your motorcycle is equipped with
partially integral brakes. Both
front and rear brakes are applied
when you pull the handbrake
lever. The footbrake lever acts
only on the rear brake.
ATTENTION
The integral braking func-
tion makes it very difficult to
spin the rear wheel by open-
ing the throttle with the front
brake applied to keep the
motorcycle stationary (burn-
out).
Damage to rear brake and clutch.
Do not attempt a burn-out
unless the ABS function is
switched OFF.
How does ABS work?
The amount of braking force that
can be transferred to the road
depends on factors that include
the coefficient of friction of the
road surface. Loose stones, ice
and snow or a wet road all have
much lower coefficients of friction
than a clean, dry asphalt surface.
The lower the coefficient of fric-
tion, the longer the braking dis-
tance.
If the rider increases braking
pressure to the extent that brak-
ing force exceeds the maximum
transferable limit, the wheels start
to lock and the vehicle loses its
directional stability; a fall is im-
minent. Before this situation
