ies are possible with the aid of
the DTC.
What are the design
features of DTC?
DTC is an assistance system
for the rider and is designed for
riding 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.
WARNING
Risky riding style
Risk of accident despite DTC
The rider is always responsi-
ble for adapting his/her driving
style.
Do not reduce the system's ex-
tra safety margin with careless
riding or unnecessary risks.
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.
The following unusual driving
conditions may result in a DTC
fault message.
Unusual riding conditions:
Driving on the rear wheel
(wheelie) for a longer period.
Rear wheel spinning in place
with front brake engaged (burn
out).
Heating up on an auxiliary
stand at idle speed or with gear
engaged.
By switching the ignition off and
on, and subsequent riding at a
minimum speed, the DTC is acti-
vated again.
