180 ENGINEERING DETAILS
Downshifting
Downshifting is assisted until
maximum rpm for the tar-
get gear to be selected is
reached. This prevents over-
revving.
Maximum engine speed
max 14600 min
-1
Upshifting
The shift assistant provides
no assistance if engine speed
drops below idle during an
upshift.
Idle speed
1270 ±50 min -1 (Engine at
regular operating tempera-
ture)
HILL START CONTROL
(HILL START CONTROL)
Hill Start Control function
Hill Start Control assistant
prevents the motorcycle from
rolling backwards uncontrolled
on gradients by intervening
specifically with the ABS brake
system without the driver
having to constantly operate
the brake lever. Pressure in
the rear brake system is built
up when Hill Start Control is
activated in order to keep the
motorcycle stationary on an
incline.
The brake pressure in the
brake system is dependent on
the gradient.
Effect of an incline on brake
pressure and drive-off
behaviour
If the motorcycle is stopped
on a gentle incline, only low
brake pressure is built up.
In this case, the brakes are
quickly released when driv-
ing off. The motorcycle can
be moved off more gently. It
is not necessary to turn the
throttle grip again.
If the motorcycle is stopped
on a steep incline, high brake
pressure is built up. In this
case, the brakes take longer
to release when driving off.
More torque is required for
driving off which also requires
the rider to turn the throttle
grip again.
Behaviour when the
motorcycle rolls or slips
If the motorcycle rolls
when Hill Start Control is
activated, the brake pressure
is increased.
If the rear wheel slips, the
brake is released again after
approx. 1 m. This prevents,
