How does DTC work?
The BMW Motorrad DTC com-
pares the wheel speeds of the
front and rear wheel. From the
speed difference the slip, and
with it the stability reserves on
the rear wheel are determined.
When a slip limit is exceeded, the
engine torque is adapted by the
engine management system.
Even with DTC, the laws of
physics cannot be overrid-
den. The driver is always respon-
sible for adapting his/her driving
style.
Do not reduce the additional
safety provided with risky
driving.
What is the design
baseline for
BMW Motorrad DTC?
BMW Motorrad DTC is designed
as an assistant system for the
rider and for use on public roads.
The extent to which the rider af-
fects DTC control can be consid-
erable (weight shifts when cor-
nering, items of luggage loose on
the motorcycle), especially when
style of riding takes rider and ma-
chine close to the limits imposed
by physics.
The system is not optimized for
special requirements resulting
under extreme weather condi-
tions offroad or on the racetrack.
You have the option of deacti-
vating the BMW Motorrad DTC
system for these circumstances.
Even with DTC, the laws of
physics cannot be overrid-
den. The driver is always respon-
sible for adapting his/her driving
style.
Do not reduce the additional
safety provided with risky
driving.
Special situations
As lean angles increase, accel-
eration potential is also progres-
sively restricted by the laws of
physics. This can result in re-
duced acceleration when coming
out of very tight curves.
To detect spinning or slipping
away of the rear wheel, the
speeds of the front and rear
wheel are compared and the
angle is considered, for example.
If these values are detected to
be implausible for a long period,
a replacement value is used for
the angle and the DTC function
is deactivated. In these cases,
a DTC error is displayed. The
