Mode changes
The riding mode can be
changed while the vehicle is
stationary with the ignition
on. Under the following
precondition, it is also possible
to change modes while riding:
No drive torque on the rear
wheel.
No brake pressure in the
brake system.
The following steps must be
taken to change the riding
mode:
Close the throttle twistgrip.
Release the brake levers.
Deactivate adaptive cruise
control.
The desired riding mode is ini-
tially preselected. The mode
change does not take place un-
til the systems in question are
all in the appropriate state.
The selection menu does not
disappear from the display until
the mode change has taken
place.
ECO mode with ShiftCam
technology
ShiftCam technology is the
bridge-builder between ultra-
high dynamism and maximum
efficiency. The full-load cams
allow full valve lift for maximum
combustion-chamber charge
and high power, whereas the
part-load cams considerably
shorten the lift of the intake
valves and open the valves to
different extents. Charge-cycle
losses are lessened by de-throt-
tling, friction is reduced, the
mixture is swirled more vig-
orously and combusted more
effectively, fuel consumption
goes down.
The ECO mode assists the
rider with ECO indicator and
engine characteristic (paramet-
risation of the electromotive
throttle controller) to keep the
engine in the operating range
of the consumption-oriented
part-load cam, so as to maxim-
ise the distance travelled with a
given quantity of fuel.
The length of the green bar
in the ECO indicator in the
TFT display visualises whether
the drive is operating in the
