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 yourzone 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 passengershould keeptheir feet on the
footpegs when the motorcycle is in motion.
Always hold the handlebar 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 handgrips under the seat with both hands.
Ride within the law and observe national and local rules.
Always respect speed limits where these are posted.
However,alwaysadjustyourspeed tothe 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 refuelling.
Be extremely careful not to spill fuel on the engine or on the
exhaust pipe when refuelling.
Do not smoke when refuelling.
While refuelling, you may inhale noxious fuel vapours.
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

ECarrying the maximum load allowed
Yourmotorcycleisdesignedforlong-distanceriding,carrying
the maximum load allowed in full safety.
Even weight distribution is critical to preserving these safety
features and avoiding trouble when performing sudden
manoeuvres or riding on bumpy roads.
Information about carrying capacity

The immobilizer system
For improved antitheft 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. 7)
The Owner receives a set of keys comprising:
- 1 RED key (A)
The “red key” is a maintenance tool and is part of the
Immobilizer system of your motorcycle. It contains the
“code” of your immobilizer system and shall not be used for
everyday use of your Ducati motorcycle. Your Ducati dealer
might ask you to bring it in for some service operations. For
safety reasons, this tool (red key)can notbe replaced.In case
the red key is needed for servicing and you can not give it to
the workshop staff, it will be necessary to change the engine
control unit, the instrument panel and the ignition switch unit
and the (high) cost for changing all these parts will be at your
charge. Store the red key in a safe place.
- 2 BLACK keys (B)
Warning
Red key A has a rubber cover for preserving it in
perfect conditions and avoiding contact with other keys.
Never remove this protection unless really needed.
The keys B 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 key A performs the same functions as the keys B, and it
is also used to wipe off and re-program other black keys, if
needed.

ENote
The three keys have a small plate (1, fig. 7) attached
that reports their identification number.
Warning
Keepthekeysindifferentplaces.Storetheplate(1,fig.
7) and the key A in a safe place.
It is also recommended to use always the same black key to
start the bike.
Code card
A CODE CARD (fig. 8) is supplied together with the keys, it
indicates the electronic code (A, fig. 9) to be used in case of
engine disabled and therefore if 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 case it is
necessaryto removeengine blockthroughthe procedurethat
uses the throttle twistgrip.
Incaseoffaultyimmobilizersystem,thefollowingprocedure
gives the chance to disable "engine block" function -
immediately signalled by the orange EOBD warning light (7,
fig. 4.1).
But this operation can be carried out only if the electronic
code indicated on the code card is known.

fig. 9
fig. 8

E
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 (7, fig. 4.1) turns off after 8
seconds.
2) Release the throttle as soon as the EOBD warning light
turns off.
3) It is now necessary to enter the electronic code
indicated on the CODE CARD delivered to the customer
together with the bike. EOBD pilot light will flash.
Count as many flashes of the EOBD pilot light (7, fig.
4.1) as the first digit of the electronic code.
Open the throttle fully. In this way the input of one
figure is acknowledged, EOBD pilot light comes on and
stays on for 4 seconds.
Failure to comply with this procedure, the EOBD pilot
light will flash for 20 times, then will come on steady.
Repeat the procedure starting from step (1).
4) Release the throttle as soon as the EOBD warning light
turns off.
5) Carry out steps 3 and 4 for the following figures of the
code until entering the last figure.
6) Release the throttle twistgrip, if the code is correct, the
EOBD warning light shall flash signalling that engine
block has been disabled. The warning light turns off
after 4 seconds. If the code is NOT correct, the EOBD
warning light stays on and it is then possible to turn the
key to OFF andrepeat the procedure, starting from point
(1), as many times as necessary (infinite).
Note
Shouldthethrottletwistgripbereleased beforetheset
time, the warning light turns on again. It is then necessary to
bring the key to OFF and restart the procedure from point (1).

18
EOperation
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, the following happens:
1) if the CPU recognised the code, the light (6, fig. 4.1) on the
instrument panel will flash briefly. This means that the
immobilizer system has recognised the key code and
enabled engine ignition. Press the START button (2, fig.
14.1), to start the engine;
2) if light (6, fig. 4.1) or EOBD light (7, fig. 4.2) stay on, it
means that the code was not acknowledged. 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 pilot light (6, fig. 4.1) still be flashing, it means
that an immobilizer system fault was reset (e.g. with the
overriding procedure through throttle grip). Turn the key to
OFF and back to ON, the immobilizer pilot light should go
back to its normal operation (see step 1).
Warning
Any important shock might damage the electronic
components fitted into the key.
Use only one key during the procedure. Failure to do so
might prevent the system from recognising the code of the
key in use.
Duplicate keys
If you need any duplicate keys, contact the DUCATI Service
network with all the keys you have left and your CODE
CARD.
DUCATI Service will program new keys and reprogram 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.
