78 TECHNOLOGY IN DETAIL
HILL START CONTROL (HILL START CON-
TROL)
with Hill Start Control OE
Function of the drive-off assistant
The Hill Start Control drive-off assistant
function prevents uncontrolled rolling back
on slopes by means of targeted intervention
in the partial integral ABS brake system,
without the rider having to continuously
operate the brake lever. When Hill Start
Control is activated, pressure builds in the
rear brake system so that the motorcycle
remains stationary on a sloping surface.
Behavior when the vehicle is rolling or
slipping
The brake pressure increases when the ve-
hicle is rolling with Hill Start Control active.
If the rear wheel skids, the brake is re-
leased again after approx. 3 ft (1 m). This
prevents, for example, the vehicle from
skidding with a locked rear wheel.
Releasing the brake when switching off
the engine or during timeout
Hill Start Control is deactivated when the
engine is switched off using the emergency-
off switch, when the side stand is folded out,
or after it times out (10 minutes).
In addition to the indicator and warning
lights, the rider is to be made aware of the
deactivation of the Hill Start Control by the
following behavior:
Brake warning jerk
The brake is released briefly and is imme-
diately reactivated.
This causes a jerking behavior that the
driver can feel.
The partial integral ABS brake system sets
a speed of approx. 0.6 to 1.2 mph (1 to
2 km/h).
The rider must brake the vehicle manually.
After two minutes, or when the brake is
applied, Hill Start Control is deactivated
completely.
When the ignition is switched off, the
holding pressure is built up immedi-
ately and without brake warning jerk.
ADAPTIVE LIGHT CONTROL
with Adaptive Lights OE
Function
In addition to the low beams, high beams
and daytime running lights or parking lights,
the headlight is equipped with separate LED
elements with their own reflectors. Depend-
ing on the angle, the LED elements are also
switched on for the low beams in order to
improve the illumination of the interior range
of the curve. The adaptive front lighting is
optimized for an angle of up to 25°.
The adaptive front lighting is activated under
the following conditions:
The angle is greater than 7°.
The speed is higher than 6.2 mph
(10 km/h).
The low beams are switched on.
