deceleration of the motorcycle,
even when cornering.
Traction control (ASC/
DTC)
How does traction control
work?
Traction control is available in
two versions
without provision for the bank
angle: Automatic Stability Con-
trol ASC
ASC is a rudimentary function
intended to prevent falls.
with provision for bank angle:
Dynamic Traction Control DTC
DTC regulation is more del-
icate and more comfortable
thanks to the additional bank
angle and acceleration informa-
tion.
Traction control compares the
front and rear wheel circumferen-
tial velocities. The differential is

used to compute slip as a meas-
ure of the reserves of stability
available at the rear wheel. If slip
exceeds a certain limit, the en-
gine management system inter-
venes and adapts engine torque
accordingly.
BMW Motorrad ASC/DTC is de-
signed as an assistant system
for the rider and for use on pub-
lic roads. The extent to which
the rider affects ASC/DTC con-
trol can be considerable (weight
shifts when cornering, items of
luggage loose on the motor-
cycle), especially when the style
of riding takes rider and machine
close to the limits imposed by
physics.
Activate Enduro riding mode for
off-roading. This mode delays
ASC/DTC intervention slightly in
order to permit controlled drifting.
The system is not optimised
for special requirements that
apply under extreme competit-
ive situations off-road or on the
track. The BMW Motorrad ASC/
DTC can be deactivated in these
cases.
WARNING
Risky riding
Risk of accident despite ASC/
DTC
Invariably, it remains the rider's
responsibility to adapt riding
style to riding conditions.
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 accelerate
is restricted more and more as
the angle of heel increases. Con-
sequently, there can be a per-
ceptible reduction in acceleration
out of very tight bends.
