For each riding mode, a coordinated set-
ting is available for the following systems:
ASC control, dynamic engine brake control
and the engine characteristics. In the ROCK
riding mode, the engine operates with high
power while in neutral, which makes the
performance capacity of the opposed-twin
engine perceptible even when the vehicle is
at a standstill. The direct throttle response
ensures unfiltered power output and makes
the power train's cylinder capacity impres-
In the RAIN riding mode: Soft throttle re-
In the ROLL riding mode: Optimal throttle
In the ROCK riding mode: Direct throttle
Automatic Stability Control (ASC)
In the RAIN riding mode: maximum sta-
bility on wet roads. Acceleration may be
reduced on dry roads.
In the ROLL riding mode: high perfor-
mance on dry roads. In poor road condi-
tions, optimum stability cannot be guaran-
In the ROCK riding mode: maximum per-
formance. Stability may be impaired on
poorly surfaced roads or if using unsuit-
Riding modes can be changed when the
vehicle is at a standstill with the ignition
switched on. A changeover while riding is
possible under the following conditions:
No drive torque at rear wheel.
No brake pressure in the braking system.
For a changeover while riding, the following
steps must be carried out:
Turn back throttle grip.
Do not actuate brake lever.
Deactivate the cruise control.
First, the desired riding mode is preselected.
The switchover does not take place until the
affected systems are in the required state.
The Selection menu does not disappear
from the display until the riding mode has
been switched over.
ENGINE DRAG TORQUE CONTROL
How does dynamic engine brake control
The purpose of the dynamic engine brake
control is to safely prevent unstable riding
conditions that are related to excess drag
torque at the rear wheel. Depending on the
road condition and driving dynamics, excess
drag torque can make the slip at the rear
wheel increase severely and impede driving
stability. The dynamic engine brake control
limits slip at the rear wheel to a safe, set-
point slip that is dependent on the mode.
Causes of excess slip at the rear wheel:
Riding in coasting overrun on a road with
low coefficient of friction (e.g. wet leaves).
Hopping when shifting gears down.
Hard brake onset in sporty riding style.
Like the BMW Motorrad ASC, the dynamic
engine brake control compares the wheel
circumferential velocities of the front and
rear wheel. The dynamic engine brake con-
trol can determine the slip, and therefore the
stability reserve, on the rear wheel using the
If the slip exceeds the respective limit value,
the engine torque is increased by slightly
opening the throttle valves. The slip is re-
duced, and the vehicle is stabilized.
Effect of the dynamic engine brake control
In the RAIN and ROLL riding modes: Maxi-
In the ROCK riding mode: Reduced inter-
vention when compared to the RAIN and
ROLL riding modes
