How does DTC work?

The BMW Motorrad DTC com-

pares the wheel speeds of the

front and rear wheel. From the

speed difference the slip, and

with it the stability reserves on

the rear wheel are determined.

When a slip limit is exceeded, the

engine torque is adapted by the

engine management system.

Even with DTC, the laws of

physics cannot be overrid-

den. The driver is always respon-

sible for adapting his/her driving

style.

Do not reduce the additional

safety provided with risky

driving.

What is the design

baseline for BMW

Motorrad DTC?

BMW Motorrad DTC is designed

as an assistant system for the

rider and for use on public roads.

The extent to which the rider af-

fects DTC control can be consid-

erable (weight shifts when cor-

nering, items of luggage loose on

the motorcycle), especially when

style of riding takes rider and ma-

chine close to the limits imposed

by physics.

The system is not optimized for

special requirements resulting

under extreme weather condi-

tions offroad or on the racetrack.

You have the option of deacti-

vating the BMW Motorrad DTC

system for these circumstances.

Even with DTC, the laws of

physics cannot be overrid-

den. The driver is always respon-

sible for adapting his/her driving

style.

Do not reduce the additional

safety provided with risky

driving.

Special situations

At an increasing angle, the accel-

eration performance is increas-

ingly limited in accordance with

physical laws. This can result in

reduced acceleration when com-

ing 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. The
