Shift assistant Pro
Your vehicle is equipped with a
shift assistant, a system originally
developed for racing and now ad-
apted for riding on public roads.
It permits upshifts and downshifts
without declutching or closing
the throttle in virtually 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
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 shift 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 assistant can take place.
Constantly maintain the corres-
ponding load condition (throttle
grip position) before and during
gear shifts using the Gear Shift
Assistant Pro. 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 shift assistant
Pro provides no assistance for
the gear change if the rider de-
clutches.
Downshifting
Downshifting is assisted until
maximum rpm for the target
gear to be selected is reached.
This prevents overrevving.
