Advantages

70-80 % of all gearshifts on a
trip can be done without using
126
the clutch.
Less relative movement
between rider and passenger
because the shift pauses are
shorter.
It is not necessary to close the
throttle when upshifting under
acceleration; the throttle valve
remains open.
When braking and downshifting
(throttle valve closed), engine
speed is automatically adjusted
by blipping the throttle.
Shift time is shorter than a
z
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 shift lever while shifting is
in progress. Once the gearshift
has completed the shift lever has
to be fully released before an-
other gearshift with the Pro shift
assistant can take place. When
shifting gears with the Pro shift
assistant, 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. The Pro shift as-
sistant provides no assistance
for the gearshift if the rider de-
clutches.
Downshifting
Downshifting is assisted until
maximum rpm for the target
gear to be selected is reached.
This prevents overreving.
Maximum engine speed
-1
max 12000 min
Upshifting
Upshifting is assisted until idle
rpm for the target gear to be
selected is reached.
This prevents the engine from
dropping below idle speed.
Idle speed
1250 min -1 (Engine at regular
operating temperature)
