Dynamic Traction Control (Dtc) - BMW S 1000 RR 2021 Rider's Manual

176 ENGINEERING DETAILS
with riding modes Pro
The damping values for the
front wheel and for the rear
wheel can be adjusted between
14 levels in the
CONFIGURATION
1: "softest" setting; level 14:
"hardest" setting). Rebound
and compression damping can
be altered on the back wheel
separately.
A spring travel sensor (racing
accessory) has to be installed
on the front forks for separ-
ate compression-stage and re-
bound-stage adjustment of the
damping values for the front
suspension.
Calibration is necessary if a
spring travel sensor has been
installed on the front forks,
an existing ride-height sensor
on the rear spring strut re-
placed, or the height of the
suspension altered. Calibration
is started in the

DYNAMIC TRACTION CON-
TROL (DTC)
How does Dynamic Traction
Control work?
DTC takes the vehicle tilt into
accounts, conveniently controls
it and is useful for improving
lap times on the racetrack.
The Dynamic Traction Control
system compares the speed
of rotation at the circumfer-
ences of the front wheel and
the rear wheel. The differen-
tial is used to compute slip as
a measure of the reserves of
stability available at the rear
wheel. If slip exceeds a certain
limit, the engine management
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.
