156 TECHNOLOGY IN DETAIL
Benefits
70-80 % of all gear changes
can be performed without
using the clutch.
Less movement between pi-
lot and pillion due to shorter
gear-change intervals.
Throttle does not have to be
closed when changing gear
under acceleration.
During deceleration and
downshifts (throttle plate
closed) the system blips the
throttle to obtain the correct
engine speed.
Shifting times are faster than
when the clutch is used to
change gears.
For the system to detect the
rider's intention to change gear,
the gearshift lever previously
not operated must be moved
against the force of the spring
by a certain amount of "over-
travel" in the desired direction
with a normal to brisk action
and held in that position until
the gear change is completed.
A further increase of the force
applied to the gearshift lever
during the gear-shift oper-
ation is not necessary. After
the gear change is completed,
the gear lever must be fully re-
leased before the Pro gearshift
assistant can execute a new
gear change. The load factor
(throttle grip position) should
remain constant both prior to
and during execution of shifts
using the Pro gearshift assis-
tant. Changing the accelerator
twist-grip position during the
gear-shift operation may cause
the function to abort and/or
the gear change to fail. The
Pro gearshift assistant does
not provide support when gear
changes are made using the
clutch.
Downshifts
Downshifts are assisted up to
the speed at which the engine
reaches maximum rpm in the
gear to be engaged. Over-
revving is thus prevented.
Maximum engine speed
max 9000 min -1
Upshifts
Upshifting is only possible
if the current RPM is higher
than the release threshold for
the next higher gear.
This prevents the idling speed
from being dropped below.
