Shift assistant
with Gearshift Assistant Pro
OE
Pro gearshift assistant
Your motorcycle is equipped with
a gearshift assistant originally de-
veloped for racing but now spe-
cially adapted for touring use.
It allows you upshift and down-
shift under almost any load con-
ditions and in virtually all engine-
speed ranges 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 pillion due to shorter gear-
change intervals.
Throttle does not have to be
closed when changing gear
under acceleration.
During deceleration and down-
shifts (throttle plate closed) the
system blips the throttle to ob-
tain 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
gearshift lever previously not op-
erated must be moved against
the force of the spring by a cer-
tain amount of "overtravel" 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
gearshift lever must be fully re-
leased before the gearshift assis-
tant Pro can execute a new gear
change. When changing gear us-
ing the gearshift assistant func-
tion, the throttle setting (throt-
tle grip position) must be kept
constant before and during the
gear-shift operation. Changing
the accelerator twist-grip position
during the gear-shift operation
may cause the function to abort
and/or the gear change to fail.
No support is provided by the
gearshift assistant during gear
changes 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.
