174 ENGINEERING DETAILS
In order for the system
to identify a request for a
gearshift, the rider has to move
the shift lever from its idle
position in the desired direction
against the force of the spring
through a certain "overtravel"
at ordinary speed or rapidly
and keep the shift lever in this
position until the gearshift is
completed. It is not necessary
to increase the force applied
to the gearshift lever while
shifting is in progress. Once
the gearshift has completed
the shift lever has to be fully
released before another
gearshift with the Gearshift
Assistant Pro can take place.
When shifting gears with
the Gear Shift Assistant, the
rider has to keep load state
(throttle twistgrip position)
constant before and during
the gearshift. A change in
the position of the throttle
twistgrip during a gearshift can
cause the function to abort
and/or lead to a missed shift.
The shift assistant provides no
assistance for the gearshift if
the rider declutches.
Downshifting
Downshifting is assisted until
maximum rpm for the tar-
get gear to be selected is
reached. This prevents over-
revving.

Upshifting
Upshifting is assisted until idle
rpm for the target gear to be

dropping below idle speed.

HILL START CONTROL
Hill Start Control function
Hill Start Control Pro is
a pullaway assistant that
operates on the partially
integral ABS system to prevent
the vehicle from rolling back
on a gradient, without the
rider having to keep pressure
applied to the brake lever.
When Hill Start Control Pro is
activated, pressure is built up in
the rear brake system to keep
