This helmet and its screen are in line with the European
standard in force at the time of their manufacture. The
European brand, the registration number and the series
number are on the white label that is sewn on the chinstrap.
In the case of the screen, the make and the registration num-
ber appear above, on the side. There are certain risks attached
to driving a motorcycle, and a helmet will never be able to
offer your head full protection against shocks. The rst and
most important form of protection is the biker himself: always
ride within your limits and in a way that is safe and reasonable.
Don’t forget that your ability to recognise external sounds (traf-
c etc…) shall be reduced by the wearing of a helmet. Always
keep your motorcycle and equipment in good condition.
For maximum protection, the helmet must be perfectly
adapted to the head and tied under the chin rmly, to minimise
the risk of serious injury – even death. A helmet is designed to
absorb a single shock. Do not continue using a helmet that has
seen a shock in its past. The shock might have caused partial
destruction of the hull and it will always have altered the dam-
ping qualities of the upholstery more or less. With this the helmet
must be replaced, even if it shows no visible signs of damage.
Please read these instructions carefully and adhere to all the
points contained therein: it constitutes important information which
will help you to have maximum protection and comfortable use
of your helmet.
WARNING
This is your ROOF DESMO helmet and we thank you for
the trust that you have in our product.

THE DESMO IS NO ORDINARY HELMET!
CHOOSING A HELMET THAT FITS WELL
EN
In order that you may benet from maximum security, the helmet must
be well adapted to the size of your
head. Put on the headphones, and
hold it rmly with both hands, you will
be incapable of turning your head at
all, in any direction, within the helmet.
If you are able to turn your head easily,
then the helmet is too big. If the hel-
met exerts too much pressure on your
head, then it is probably too small and
there is the risk of headaches and your
concentration being impaired. Once
the chinstrap is tightened, you should
not be tilting your head within the hel-
met. Ask your ROOF helmets dealer for advice: they should be able to
help you nd the helmet that ts your head perfectly.

A FEW TIPS
Before setting off, always ensure that your helmet ts properly and that
it is in perfect working water. Take driving lessons and avoid using the
road if you are tired or under the inuence of alcohol or drugs. Do not
make modications to your helmet or attach anything to it. Do not paint
your helmet as this may damage it; if you decide to paint it regardless,
use only paints which dry by evaporation. Check that your screen is
clean and free of scratches. Never go on the road with your helmet
hanging on a hook. Don’t let your helmet be exposed to excessively
high temperatures (e.g.: near heating devices or to sunlight behind a
car windshield). Never buy a second helmet – you never know whether
it has already seen a real shock in its past. Never let another person use
your helmet, because with this there will be the risk of it no longer being
able to t your head properly.

SINGLE SHOCK RULE
EN
www.roof.fr
Your helmet is designed to absorb a single shock: the outer shell
effectively distributes the force of the impact across the full surface of
the helmet (see A). The quality of the nishing of ROOF helmets is such
that it is impossible to know whether or not it has absorbed a shock: it
does not show any visible markings. The padding of the ROOF DESMO
helmet inside of the shell is composed of damping materials of
progressive density. This padding layer alters dramatically during and
after a collision (see B), but the damage that it suffers is barely visible as
it is sandwiched between the shell and the comfort padding. For these
reasons, all helmets that have known any major impact (even if the
effects are invisible to the naked eye) must be replaced.
AB
POSITION OF USE
EN
The DESMO helmet belongs to the family of modular helmets. It is
approved by the European Standard E22-05 and is in the Integral class
when the chinstrap is closed and in the Jet class when it is open. In the
Jet position, the chin guard must be placed in the rear abutment. For
your security, ROOF recommends that a DESMO helmet be worn in the
Integral position. The chinstrap joint is equipped with an anti-loosening
device (red ring). It is not worth lubricating the joint or gripping it tightly.
20
The chinbar is locked in the Integral position with the aid of two
automatic locks that are located on each side of it. To lock your chin-
bar, fold it there up until the visible outbreak of the mechanism (see A).
To unlock your chinbar, simultaneously press the two buttons (lower and
upper) located on its front. Then, move the chinbar backward (see B).

MICROMETRICAL CHINSTRAP
EN
www.roof.fr
HOW TO USE THE ROOF MICROMETRICAL CHINSTRAP
Correct tension of the strap is essential for your security: it will prevent
loosening risks in the case of an accident. Incorrect adjustment or
misuse of the micrometric buckle can result in loss of the helmet, with
grave consequences to your health and even your life.
THE CHINSTRAP MUST BE CLOSED WHEN YOU ARE ON THE ROAD!
CLOSING / OPENING
The chinstrap should be snug yet comfortable. Close the chinstrap by
inserting the toothed portion in the red buckle. Press the toothed
portion until the chinstrap is stretched. For optimal closure, ensure that
the toothed portion is inserted at least 5 teeth into the clasp.
If the chinstrap clamps you excessively or, on
the contrary, the helmet has a tendency to
become unsettled, it is necessary to perform
a pre-setting of the flexible strand of the
chinstrap.
To open the chinstrap, pull the strap in order
to lift the red part of the clasp and remove the
toothed portion (see opposite).
ADJUSTMENT OF THE FLEXIBLE STRAND OF THE CHINSTRAP
Remove the helmet. Slide the exible strand of the chinstrap through the
loop components to lengthen or shorten it. Repeat this operation until
the toothed portion optimally closes in the red shutter.
INSPECTION AND MAINTENANCE
In order to ensure the proper functioning of the micrometric buckle, it is
important to check that the red part rotates freely between its open po-
sition and its closed position, with its spring mechanism. Sometimes salt
and sand block the clasp when it is not properly maintained. So don’t
forget to clean and oil the mechanism regularly. Then check again that
the chinstrap is properly adjusted before setting off.

! WARNING !
EXTERNAL
Only clean your helmet using warm water and mild soap. Never use petrol,
thinner, benzine or other solvents, as these products risk damaging the
parts of the helmet and abolishing its impact protection properties.
INTERIOR
When your headset is removed, do not do anything with the EPS liner;
do not wash it or apply any solvents. You might be questioning its
damping qualities.
The DESMO helmet has an internal comfort system which can be fully

The DESMO is equipped with an upper-level air intake and two air out-
lets which are located on the back of the helmet. The rear outputs allow
for air decompression (the Venturi effect). In the open position, fresh air
enters through the top of the helmet for diffuse ventilation, and hot and
humid air escapes through the outlets that are located on the back.
To allow for ventilation it is necessary to open the air intake as well as
the outlets; conversely, you close the air intake and outlets to prevent
ventilation.
UPPER AIR INTAKES
OPENING AND CLOSING OF THE UPPER AIR INTAKE
To open it, press on at least one of the two aps (see A). To close it, push
the button at the back of the helmet so you can take out the two aps
(see B).

DISASSEMBLY/ASSEMBLY OF THE SCREEN
The DESMO mechanism is a special one; it is essential to follow these
instructions and to use the DESMO Tool provided with the helmet to
disassemble and re-assemble its screen. (However, loss of the DESMO tool does
not prevent the assembly of the mechanism. Go to www.roof.fr, assembly/disassembly ins-
truction videos are there for you.)
! WARNING !
PHASE 1: When you put your helmet on a soft
and stable surface, it is essential to open the
chinbar to the Jet position. Then unscrew
the 2 screws using the hex wrench (4mm)
included on the ROOF key-chain.
PHASE 2: Separate the two ends of the chinbar
to release it from the plates that are attached
to the shell. Position your chinbar next to your
helmet, on a soft and stable surface.
PHASE 3: Using the thin end of the ROOF key-
chain, unclip the cam mechanism by per-
forming a lever arm movement (to the right
and left). Make sure that it doesn’t come into
contact with the shell.

PHASE 4: Grab the whole screen mechanism
on the right and left, then remove the
assembly in the directions of the exteriors to
free the screen and its mechanism from the
plates that are xed on the shell.
PHASE 5: To replace a screen on your helmet,
x the DESMO tool on the right / left screen
mechanisms. This specic tool, composed of
two symmetrical parts, will allow for a simple
and intuitive assembly. Position the two parts
of the tool on your screen as shown in the
illustration opposite. Ensure that the
mechanism is locked by the 4 clips which are
indicated by red arrows in the illustration.
PHASE 6: Clip the two lower parts of the
DESMO tool on the locking pins (1) that are
located on each side of the shell.
With your screen now removed, you can clean it before putting it back
on your helmet or change a screen accessory. If you are going to clean
your screen, it is essential to follow the recommendations on page 15.
If mounting a screen accessory, please place your original screen in
the plastic cover of your new screen so as to limit all scratch risks, then
follow the procedure.

PHASE 8: Use your thumb to apply a fair
amount of pressure at the position indicated
(3) so as to x the cam mechanism on each
side of the shell. There is signicant noise with
the proper xing of the mechanism.
PHASE 9: Your screen is now in position and
the mechanism is properly secured. Remove
the two parts of the DESMO tool by sliding
your index into the groove provided for this
purpose and pulling outward. Then remove
the DESMO tool from the locking pins (1)
located on each side of the shell. Your screen
is now lowered into the Jet position.
PHASE 10: Without rotating the screen or the
cam mechanism, engage the chinbar on
the axes of the plates (2) xed on each side
of the shell. Warning the chinbar absolutely
must be xed in a vertical position (see op-
posite). Then tighten the chinbar to the right
and the left, without forcing too much.
PHASE 7: Slide the two parts of the tool on the
axes of the plates (2) that are xed on each
side of the shell.

CLEANING THE SCREEN
It is important to maintain good visibility as far as your screen is concer-
ned. If the screen is scratched, replace it; especially if you are going to
be driving at night. Tinted screens are explicitly only for day use; they
should never be used at night or in poor visibility. This screen is made of
polycarbonate: never use alcohol, solvents or hydrocarbons to clean
the windows. Do not apply any varnish or adhesives. All these products
can result in deterioration of the physical and optical qualities of this
screen. Treat the screen gently, especially when you clean it, so that its
anti-scratch and anti-fog measures will remain effective. Clean it only
with clean water then use a soft cloth to wipe it gently. For optimum
operation of the anti-fog mechanism, regular cleaning is advised.
! WARNING !
In the interest of your security, refrain from making manipulations to your
helmet when you are riding.
We remind you that ROOF recommends that DESMO be used in the
Integral position.
ROOF advises you to ensure good safekeeping of this user guide.

Ensure that the operation of your DESMO helmet is identical to the same
as what it was prior to your assembly; if it isn’t, repeat the procedure.
You will nd videos dedicated to helping you with the assembly/disas-
sembly of your helmet on the site www.roof.fr
If this operation is correct, then your helmet is ready – have good trip!
