TECHNOLOGY IN DETAIL
ditional turning of the throttle
grip is hardly required.
Stopping on a steeper slope
increases the amount of brake
pressure built up. The brake
is a bit slower to release
when riding off. More torque
is required to ride off, making
additional turning of the
throttle grip necessary.
Behavior when the vehicle is
rolling back or slipping
The brake pressure increases
when the vehicle is rolling
back with the Hill Start Con-
trol activated.
If the rear wheel slips, the
brake is released again after
approx. 1 m. This prevents
the vehicle from slipping with
a locked rear wheel, for exam-
ple.
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 indicator and
warning lights, the following
vehicle behavior should make
the rider aware that the Hill
Start Control is deactivated:
Brake warning jerk
The brake is released briefly
and is immediately reacti-
vated.
This causes a jerking behavior
that the rider can feel.
The partial integral ABS brake
system sets a speed of ap-
prox. 1–2 km/h.
The rider must brake the vehi-
cle manually.
After two minutes, or when
the brake is applied, Hill Start
Control is deactivated com-
pletely.
When the ignition
is switched off, the
holding pressure is built up
immediately and without brake
warning jerk.
SHIFTCAM
Principle of ShiftCam function
The motorcycle is equipped
with the BMW ShiftCam tech-
nology - a technique for vary-
ing the valve timing and the
valve stroke on the intake side.
The centerpiece of this technol-
ogy is a one-piece intake trip
camshaft that has two cams
per valve to be actuated: one
for partial load and one for full
