without operating the clutch or
accelerator.
Benefits
70-80 % of all gear changes
can be performed without us-
ing the clutch.
Less movement between pilot
and passenger due to shorter
gear-change intervals.
Throttle valve does not have to
be closed when changing gear
under acceleration.
During deceleration and down-
shifts (throttle plate closed) the
system blips the throttle valve
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 rid-
er's intention to change gear, the
gear lever previously not oper-
ated must be moved against the
force of the spring by a certain
amount of "overtravel" in the de-
sired direction with a normal to
brisk action and held in that po-
sition 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
gearshift lever must be fully re-
leased before the Pro Gear Shift
Assistant can execute a new gear
change. When shifting gears us-
ing the Gear Shift Assistant Pro,
the load condition (throttle grip
position) must remain constant
both prior to and during the gear
shift. Changing the accelerator
twist-grip position during the
gear-shift sequence may cause
the function to abort and/or the
gear change to fail. The Gear
Shift Assistant Pro does not pro-
vide support when gear shifts are
made with clutch control. 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 12000 min -1
Upshifts
The Gear Shift Assistant does
not provide added support
when the engine speed falls
below idle speed in the new
gear.
Idle speed

erating temperature)
