Shift assistant

Shift assistant Pro
Your motorcycle is equipped with
z
a gearshift assistant originally de-
veloped for racing but now spe-
cially adapted for use in public
highway traffic. It allows you up-
shift and downshift under almost
any load conditions and in vir-
tually 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
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 gear
lever during the gear-shift op-
eration is not necessary. After
the gear change is completed,
the gear 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 Pro
gearshift assistant does not pro-
vide 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
