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 capability 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 DTC
compares the speeds of the front
and rear wheel and takes the an-
gle of inclination and other fac-
tors into account.
If the values for the angle of in-
clination are detected to be im-
plausible for a long period, a sub-
stitute value is used for the angle
of inclination/the DTC is turned
off. In these cases, a DTC er-
ror is displayed. A self-diagnosis
routine must be completed be-
fore the fault memory entry will
be displayed.
Under the following unusual
riding conditions, the
BMW Motorrad Traction
Control may be switched off
automatically.
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.
Dynamic engine brake
control
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.
