system intervenes and adapts
engine torque accordingly.
DTC can only provide support
within the physical limits. The
physical limits are strongly de-
pendent on the road surface,
road temperatures, tyre choice
and tyre temperature. There
is the danger of overheating
when using unsuitable tyres on
the race track.
WARNING
Risky riding
Risk of accident despite DTC
Invariably, the rider bears
responsibility for assessing
road and traffic conditions
and adopting his or her style
of riding accordingly.
Do not take risks that would
negate the additional safety
offered by this system.
Special situations
In accordance with the laws of
physics, the ability to acceler-
ate is restricted more and more
as the angle of heel increases.
Consequently, there can be a
perceptible reduction in accel-
eration out of very tight bends.
With DTC, the speeds of the
front and rear wheels are
compared and the angle of
heel taken into account as one
means of detecting the rear
wheel's incipient tendency to
spin or slip sideways.
If the lean angle values are
identified as implausible over
an extended period of time,
a substitute value is used for
the lean angle or the DTC is
switched off. Under these cir-
cumstances the indicator for
a DTC fault shows. Self-dia-
gnosis has to complete before
fault messages can be issued.
The BMW Motorrad traction
control may switch off auto-
matically under the exceptional
riding conditions outlined be-
low.
Exceptional riding conditions:
Riding for a lengthy period
with the front wheel lifted off
the ground (wheelie).
Rear wheel rotating with the
vehicle held stationary by ap-
plying the front brake (burn-
out).
Heating up with the motor-
cycle on an auxiliary stand,
in neutral or with a gear en-
gaged.
