BMW R 1250RS, Rider'S Manual

Page: 164 / 279

The brake pressure in the brake
system is dependent on the
gradient.
Effect of an incline on brake
pressure and drive-off
behaviour
If the motorcycle is stopped on
a gentle incline, only low brake
pressure is built up. In this
case, the brakes are quickly
released when driving off. The
motorcycle can be moved off
more gently. It is not necessary
to turn the throttle grip again.
If the motorcycle is stopped
on a steep incline, high brake
pressure is built up. In this
case, the brakes take longer to
release when driving off. More
torque is required for driving off
which also requires the rider to
turn the throttle grip again.
Behaviour when the
motorcycle rolls or slips
If the motorcycle rolls when Hill
Start Control is activated, the
brake pressure is increased.
If the rear wheel slips, the
brake is released again after
approx. 1 m. This prevents,
for example, slipping due to a
blocked rear wheel.
Releasing brake when
stopping the engine or
timeout
Hill Start Control is deactivated
when the engine is stopped us-
ing the emergency-off switch,
when the side stand is folded out
or after timeout (10 minutes).
In addition to the indicator and
warning lights, the rider should
be made aware that Hill Start
Control has been deactivated by
the following behaviour:
Brake warning jolt
The brake is released briefly
and reactivated immediately.
This creates a jolt which the
rider feels.
The ABS brake system with
partially integral function sets a
speed of approx. 1-2 km/h.
The rider must brake the mo-
torcycle manually.
After two minutes, or when
the brake is actuated, Hill Start
Control is completely deactiv-
ated.
NOTICE
The holding pressure is released
immediately without a brake
warning jolt as soon as the
ignition is switched off.
