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 benet 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 inuence of alcohol or drugs. Do not
make modications 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.

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.

CLEANING THE HELMET

! 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
removed. The elements consisting of fabric (only) can be washed. Use
a mild soap, rinse it abundantly, and do not let it dry near a heat source
(e.g. a radiator).
COMFORT CHEEKS
COMFORT CHEEKS EXCHANGE
You can adjust the comfort of the helmet to your head: get cheeks of
different sizes from your dealer.
REMOVAL OF COMFORT CHEEKS
Open the chinstrap, then pull the top
of the cheek towards the interior of the
helmet to unclip the three pressures (see
opposite). Then slide the cheek along the
strap to remove it.
