How does DTC work?
DTC compares the wheel speeds
of the front and rear wheels. Dif-
ferences in the relative rotation
speeds allow the system to de-
termine the slip rate, and thus
the stability reserves at the rear
wheel. The engine-management
system adapts the engine torque
when the slip limit is exceeded.
DTC is equipped with an angle
sensor, enabling it to control
z
the wheel slip more sensitively
in curves. As a result, more dy-
namic driving condition are possi-
ble with the same stability. In the
DYNAMIC mode minor wheelies
can be ridden with the support of
DTC.
What are the design
features of DTC?
DTC is an assistance system
for the rider and is designed for
driving on public roads. The ex-
tent to which the rider affects
DTC control can be considerable
(weight shifts when cornering,
loose luggage on the motorcy-
cle), especially when approaching
the limits imposed by the laws of
physics.
The system is not optimized for
special requirements resulting
under extreme weather condi-
tions on the racetrack. DTC can
be deactivated for riding in these
conditions.
Even with DTC, the laws of
physics cannot be overrid-
den. The rider 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. A
self-diagnosis routine must be
completed before the error will
be displayed.
