Gear Shift Assistant Pro
Your vehicle is equipped with
Gear Shift Assistant Pro, a sys-
tem originally developed for ra-
cing and now adapted for the
touring sector. It permits upshifts
and downshifts without declutch-
ing or closing the throttle in virtu-
ally all load and rpm ranges.
Advantages
70-80 % of all gearshifts on a
trip can be done without using
the clutch.
Less relative movement
between rider and passenger
because the shift pauses are
shorter.
It is not necessary to close the
throttle valve when shifting un-
der acceleration.
When braking and downshifting
(throttle valve closed), engine
speed is adjusted by blipping
OE
the throttle.
Shift time is shorter than a
gearshift with clutch actuation.
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 dir-
ection against the force of the
spring through a certain "over-
travel" at ordinary speed or rap-
idly 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 Pro shift assist-
ant can take place. When shifting
gears with the Gear Shift Assist-
ant Pro, the rider has to keep
load state (throttle twistgrip pos-
ition) 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. Gear Shift Assist-
ant Pro provides no assistance
for the gearshift if the rider de-
clutches.
