Useful information for safe riding

Warning

Read this section before riding your motorcycle.

Accidents are frequently due to inexperience. Always
make sure you have your licence with you when riding;
you need a valid licence to be entitled to ride your
motorcycle.
Do not lend your motorcycle to inexperienced riders or
who do not hold a valid licence.
Both rider and pillion passenger must always wear a
safety helmet.
Wear proper clothing, with no loose items or accessories
that may become tangled in the controls or limit your
zone of vision.
Never start or run the engine indoors. Exhaust gases are
poisonous and may lead to loss of consciousness or even
death within a short time.
Both rider and pillion passenger should keep their feet on
the footpegs when the motorcycle is in motion.
Always hold the handlebars firmly with both hands so
you will be ready for sudden changes of direction or in
the road surface. The pillion passenger should always
hold on to the suitable rear handgrip with both hands.
Ride within the law and observe national and local rules.
Always respect speed limits where these are posted.
However, always adjust your speed to the visibility, road
and traffic conditions you are riding in.
Always signal your intention to turn or pull to the next
lane in good time using the suitable turn indicators.

Be sure you are clearly visible and do not ride within the
blind spot of vehicles ahead.
Be very careful when tackling road junctions, or when
riding in the areas near exits from private grounds, car
parks or on slip roads to access motorways.
Always turn off the engine when refueling.
Be extremely careful not to spill fuel on the engine or on
the exhaust pipe when refueling.
Do not smoke when refueling.
While refueling, you may inhale noxious fuel vapors.
Should any fuel drops be spilled on your skin or clothing,
immediately wash with soap and water and change your
clothing.
Always remove the key when you leave your motorcycle
unattended.
The engine, exhaust pipes, and mufflers stay hot for a
long time.

Warning

The exhaust system might be hot, even after
engine is switched off; pay particular attention not to
touch exhaust system with any body part and do not park
the vehicle next to inflammable material (wood, leaves
etc.).

Park your motorcycle where no one is likely to hit it and
use the side/center stand.
Never park on uneven or soft ground or your motorcycle
may fall over.

E

7

Carrying the maximum load allowed

Your motorcycle is designed for long-distance riding,
carrying the maximum load allowed in full safety and
comfort.
Even weight distribution is critical to preserving these
safety features and avoiding trouble when performing
sudden manoeuvres or riding on bumpy roads.

Important

E

When the side panniers are fitted, it is
recommended to never exceed 120 Km/h.
Further reduce speed if tyres are worn down and when
riding on poor road surface or with poor visibility.

8

Information about carrying capacity

The total weight of the motorcycle in running order
including rider, pillion passenger, luggage and additional
accessories should not exceed 420 Kg.
The weight of luggage alone should never exceed 23 Kg
divided as follows (fig. 1):

max 9 kg for each side pannier;
max 5 kg for tank bag.

fig. 1

Try to arrange your luggage or heavy accessories in the
lowest possible position and close to motorcycle centre.
Be sure to secure the luggage to the supports provided
on the motorcycle as firmly as possible. Improperly
secured luggage may affect stability.
Never fix bulky or heavy objects to the handlebar or to
the front mud guard as this would affect stability and
cause danger.
Do not insert any objects you may need to carry into the
gaps of the frame as these may foul moving parts.
If you install the side panniers (available from Ducati
Spare Parts Department):
sort luggage and accessories so to distribute weight
evenly and then arrange them in the panniers so that
they are well balanced; lock both side panniers using the
suitable key lock.
Make sure the tyres are inflated to the proper pressure
indicated at page 86 and that they are in good condition.

is switched off and will be turned on only upon the
following Key-ON.

- After having used the bike, with headlight on, if the
engine is stopped via the ENGINE KILL switch (2, fig. 21),
after 60 seconds from engine stop, the headlight is
turned off and will be turned on upon the following
engine start-up.

24

The immobilizer system

For improved anti-theft protection, the motorcycle is
equipped with an IMMOBILIZER, an electronic system
that inhibits engine operation whenever the ignition
switch is turned off.
Accommodated in the handgrip of each ignition key is an
electronic device that modulates an output signal. This
signal is generated by a special antenna incorporated in
the switch when the ignition is turned on and changes
every time. The modulated signal acts as a “password”
and tells the CPU that an "authorised" ignition key is
being used to start up the engine. When the CPU
recognises the signal, it enables engine start-up.

Keys (fig. 14)

1

B

A

The Owner receives a set of keys comprising:

- 1 RED key (A)

- 2 BLACK keys (B)

Warning

Red key has a rubber cover for preserving it in
perfect conditions and avoiding contact with other keys.
Never remove this protection unless really needed.

The black keys are regular ignition keys and are used to:

- start up the engine

- open the lock of the fuel tank filler plug

- open the seat lock.

The red key performs the same functions as the black
keys, and is also used to wipe off and re-program other
black keys, if needed.

Warning

Any important shock might damage the electronic
components fitted into the key.

Note

The three keys have a small plate (1) attached that

reports their identification number.

Warning

Keep the keys in different places. Store the plate (1)
and the red key in a safe place.
It is also recommended to use always the same black
key to start the bike.

E

fig. 14

25

Code card

A CODE CARD (fig. 15) is supplied together with the
keys, it indicates the electronic code (A, fig. 16) to be
used in case of emergency start-up and the engine will
not start up after the key-ON.

Warning

Keep the CODE CARD in a safe place. However, it
is advisable to keep the electronic code printed on the
CODE CARD handy when you ride your motorcycle, in

E

case it is necessary to remove engine block through the
procedure that uses the throttle twistgrip (see page 35).
In case of faulty immobilizer system, this procedure gives
the chance to disable "engine block" function -signalled by
the orange EOBD warning light (5, fig. 6).

26

fig. 15

A

fig. 16

Procedure to disable immobilizer engine block
through throttle twistgrip

1) Turn the key to ON and fully open throttle. Keep it
open. The EOBD warning light turns off after 8 seconds.

2) Release the throttle as soon as the EOBD warning
light turns off.

3) EOBD pilot light will flash. Count a number of flashes
corresponding to the first figure of the code printed on
the CODE CARD, open full throttle and keep the position
for 2 seconds, then release. In this way the input of one
figure is acknowledged, EOBD pilot light comes on and
stays on for 4 seconds. Carry out the same procedure for
the following figures of the code. Failure to do so will
cause the EOBD pilot light to flash 20 times, then it will
stay on. This means that the procedure has been
aborted. It will be necessary to turn the key to OFF and
restart from point 1.

4) Repeat operations described in point 3 up to the last
figure of the code.

5) Release the throttle twistgrip, if the code is correct the
following two conditions may occur:
A) the EOBD warning light shall flash signalling that
engine block has been disabled. The warning light turns
off after 4 seconds or if engine revolutions go over the
limit value of 1000 rpm.
B) the IMMO light (3, fig. 5.1-5.2) flashes until engine
rpm get above 1000 rpm, or until engine is re-started.

6) If the code is NOT correct, the EOBD warning light and
the IMMO light stay on and it is then possible to repeat
the procedure, starting from point 2, as many times as
necessary (infinite).

Note

Should the throttle twistgrip be released before the
set time, the warning light turns on again. It is then
necessary to bring the key to OFF and restart the
procedure from point 1.

27

E

Operation

When the ignition key is turned to OFF, the immobilizer
inhibits engine operation.
When the ignition key is turned back to ON to start the
engine (Key-ON), the following happens:

1) if the CPU recognised the code, the IMMO light on the
instrument panel will flash briefly. This means that the
immobilizer system has recognised the key code and
enabled engine ignition. When you press the start
button, the engine will start up.

E

2) If the IMMO light stays on, it means that the code has
not been recognised. When this is the case, turn the
ignition key back to OFF and then to ON again. If the
engine still does not start, try with another black key.
If the other key does not work out either, contact the
DUCATI Service network.

3) Should the IMMO pilot light still be flashing, it means
that an immobilizer system fault was reset (e.g. with the
overriding procedure through throttle grip).

Important

Use only one key during the procedure. Failure to
do so might prevent the system from recognizing the
code of the key in use.

28

Duplicate keys

If you need any additional key, contact the DUCATI
Service network with all the keys you have left and your
CODE CARD.
DUCATI Service will program new keys and re-program
your original keys, up to 8 keys in total.
You may be asked to identify yourself as the legitimate
owner of the motorcycle. Be sure you have any
documents you might need to this end ready.
The codes of any keys not submitted will be wiped off
from the memory to make those keys unserviceable in
case they have been lost.

Note

If you sell your motorcycle, do not forget to give all

keys and the CODE CARD to the new owner.
