Pressure adaptation
Compare the RDC value on the
display with the value in the
table on the back cover of the
rider's manual. Then use the
air-line gauge at a service sta-
tion to compensate for the dif-
ference between the RDC read-
ing and the value in the table.
Example
According to the Rider's
Manual, the tyre pressure
should be:
2.5 bar
The multifunction display
shows the following reading:
2.3 bar
So pressure is low by:
0.2 bar
The gauge on the air line
shows:
2.4 bar
You must now increase tyre
pressure until the value is:
2.6 bar
GEAR SHIFT ASSISTANT
with shift assistant Pro OE
Gear Shift Assistant Pro
Your vehicle is equipped with
Gear Shift Assistant Pro, a
system originally developed for
racing and now adapted for
the touring sector. 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
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
the shift lever from its idle
position in the desired direction
against the force of the spring
through a certain "overtravel"
