GEAR SHIFT ASSISTANT

with shift assistant Pro
Gear Shift Assistant Pro
Your vehicle is equipped with a
shift assistant, a system origin-
ally developed for racing and
now adapted for riding on pub-
lic roads. It permits upshifts
and downshifts without de-
clutching 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
under acceleration.
When braking and downshift-
ing (throttle valve closed),
engine speed is adjusted by
blipping the throttle.
Shift time is shorter than a
gearshift with clutch actu-
ation.
In order for the system
to identify a request for a
gearshift, the rider has to move
OE
the shift lever from its idle
position in the desired direction
against the force of the spring
through a certain "overtravel"
at ordinary speed or rapidly
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
