Temperature

compensation

Tyre pressure is a temperature-

sensitive variable: pressure in-

creases as tyre temperature rises

and decreases as tyre temper-

ature drops. Tyre temperature

depends on ambient temperat-

ure, on the style of riding and the

duration of the ride.

The tyre-pressure readings

shown by the multifunction

display are temperature-

compensated; the reference tyre

temperature for these readings

is always 20 °C. The air lines

available to the public in petrol

stations and motorway service

areas have gauges that do not

compensate for temperature; the

reading shown by a gauge of

this nature is the temperature-

dependent tyre pressure. In

most instances, therefore, these

gauge readings will not tally with

the pressures shown by the

multifunction display.

Pressure adaptation

Compare the RDC readings

on the multifunction display

with the value in the table on

the inside cover of the Rider's

Manual. Then use the air line to

compensate for the difference

between the RDC reading and

the value in the table.

Example: According to the Rider-

's Manual, tyre pressure should

be 2.5 bar, but the reading in the

multifunction display is 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 by the 0.2 bar dif-

ference between the value in the

table and the RDC reading; when

the air-line gauge shows 2.6 bar,

the tyre is inflated to the correct

pressure.

Suspension adjustments

Depending on the load on the

motorcycle, the appropriate load

status must first be selected

when the motorcycle is station-

ary. The damping characterist-

ics on both spring struts and the

spring mount and the spring rate

on the rear spring strut are ad-

justed on the basis of the rid-

ing mode that is then selected.

If the selected driving mode is

changed, the damping character-

istics on both spring struts and

the spring rate on the rear spring

strut are also adjusted. This al-

lows the suspension to be very

accurately adapted to all riding

conditions, even when the motor-

cycle is in motion.
