Checking the oil level with the
engine cold or after no more than
a short ride will lead to misinter-
pretation; this in turn, means that
the engine will be operated with
the incorrect quantity of oil.
In order to ensure that the en-
gine oil level is read correctly,
check the oil level only after a
lengthy trip.
Allow the engine to idle until
the fan starts up, then allow it
to idle one minute longer.
Make sure the ground is level
and firm and hold the motor-
cycle upright.
Switch off the engine.

TyresChecking tyre tread depthMake sure the ground is level
and firm and place the motor-
cycle on its stand.
Measure the tyre tread depth
in the main tread grooves with
wear marks.
Tyres have wear indicators
integrated into the main
tread grooves. The tyre is worn
out when the tyre tread has worn
down to the level of the marks.
The locations of the marks are
indicated on the edge of the tyre,
e.g. by the letters TI, TWI or by
an arrow.
If the tyre tread no longer com-
plies with the minimum legally
required tread depth:
Replace tyre.

Compliance with the points be-
low is important in order to max-
imise battery life:
Keep the surface of the battery
clean and dry
Do not open the battery
Do not top up with water
Be sure to read and comply
with the instructions for char-
ging the battery on the follow-
ing pages
Do not turn the battery upside
down
If the battery is not discon-
nected, the on-board elec-
tronics (e.g. clock, etc.) gradually
drain the battery. This can cause
the battery to run flat. If this hap-
pens, warranty claims will not be
accepted.
If the motorcycle is to be out of
use for more than four weeks,
disconnect the battery or con-
nect a suitable trickle charger to
the battery.
Charging battery when
connected
Charging the connected
battery directly at the bat-
tery terminals can damage the
vehicle electronics.
Always disconnect the battery
from the on-board circuits be-
fore recharging it with a charger
connected directly to the battery
posts.
If you switch on the igni-
tion and the multifunction
display and telltale lights fail to
light up, the battery is completely
flat. Attempting to charge a com-
pletely flat battery via the on-
board socket can cause damage
to the motorcycle's electronics.
If a battery has discharged to the
extent that it is completely flat, it
has to be disconnected from the
on-board circuits and charged
with the charger connected dir-
ectly to the battery posts.Charge via the power socket
(OE), with the battery connec-
ted to the motorcycle's on-
board electrical system.
Comply with the operating in-
structions of the charger.
Charging battery when
disconnectedCharge the battery using a
suitable charger.
Comply with the operating in-
structions of the charger.
Once the battery is fully
charged, disconnect the
charger's terminal clips from
the battery terminals.
The battery has to be re-
charged at regular intervals
in the course of a lengthy period
of disuse. See the instructions
for caring for your battery. Al-
ways fully recharge the battery
before restoring it to use
