Unusual riding conditions:
Riding on the rear wheel
(wheelie) for a longer period.
Rear wheel spinning in place
with front wheel brake engaged
(burn out).
Warming up the engine on an
auxiliary stand at idle or with
gear engaged.
Minimum speed for DTC
activation
min 3 mph (min 5 km/h)
If the front wheel loses con-
tact with the ground under ex-
treme acceleration, the ASC or
DTC function reduces the engine
torque in the
RAIN
and
ROAD
rid-
ing modes until the front wheel
makes contact with the ground
again.
In the
DYNAMIC
setting of the
DTC, the front wheel lift-off de-
tection permits brief wheelies.
The front wheel lift-off detection
is switched off in riding mode
DYNAMIC PRO
.
BMW Motorrad recommends
that you respond to the front
wheel lifting off by twisting back
the throttle grip somewhat to re-
turn to a stable riding condition
as quickly as possible.
In the RAIN, ROAD and
DYNAMIC riding modes, the
DTC settings corresponds to the
riding mode.
DTC can be set differently in the
DYNAMIC PRO riding mode.

How does dynamic engine
brake control work?
The purpose of the dynamic en-
gine brake control is to safely
prevent unstable riding condi-
tions that are related to excess
drag torque at the rear wheel.
Depending on the road condition
and riding dynamics, excess drag
torque can make the drive slip at
the rear wheel increase severely
and impede riding stability. The
dynamic engine brake control
limits slip at the rear wheel to a
safe, setpoint slip that is depen-
dent on the mode and angle.
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 rid-
ing style.
