a motorcycle. If you use the helmet for anything
else, it may not provide sufficient protection in an
accident.

No helmet can protect the wearer against all
possible impact scenarios.

For maximum protection, the Sena Momentum
Bluetooth Helmet must fit properly on the head
and its retention strap securely fastened under the
chin. With the retention system comfortably but
firmly adjusted, the helmet should allow sufficient
peripheral vision when secured. If the helmet is too
large, it may move on your head while riding. If the

Inspection

helmet can be removed when pulled from the back
in an upward and forward direction, it’s not fitted
properly. This could cause the helmet to obstruct
your vision while riding or come off in an accident,
resulting in personal injury or death. Please refer
to Section 1.6: “Wearing the Helmet” for more
details about properly securing and wearing your
helmet.

2. Gently pull the chinstrap outward and slide
the helmet onto your head.

Note: A “chinstrap” is the nylon webbing
that goes through the D-Rings.

3. Route the chinstrap under your chin, then
thread it through both D-Rings.

4. To fasten securely, thread chinstrap back
through the D-Ring closest to your neck,
and pull.

attached to the D-Rings.

2. Pull the chinstrap out from within the

1.7.1 Checking the Exterior

Check the helmet regularly for damage.
Small, superficial scratches will not impair the
helmet’s protective qualities. In the case of
more serious damage (cracks, dents, flaking
and cracking paint, etc.), the helmet should no
longer be used.

1.7. 2 Checking the Chinstrap

1. Ensure that the chinstrap is properly routed
under your chin.

2. To test the chinstrap tension, slip your index
finger under the chinstrap and pull. If the

Pre-Ride

Helmet

Inspection

chinstrap is loose under the chin, it needs to
be tightened. If the chinstrap loosens when
you pull on it, the helmet is not properly
fitted. Undo the chinstrap completely and
try fastening it again, then repeat the test.

3. If you are unable to fasten the chinstrap so
that it fits firmly against the chin, check that
your helmet is still the right size for you.

Note: Repeat the test after each
adjustment.

Caution: : Never ride with the chinstrap
unfastened or incorrectly adjusted. The
chinstrap should fit correctly and should not
become loose when pulled. The fastener
is not correctly closed if the chinstrap
becomes loose when pulled.

Wearing the

Before every ride, clean the face shield,
check that it functions properly and that
its surface is scratch- and crack-free. A
malfunctioning, badly scratched or dirty shield
will considerably impair your vision and should
be replaced before riding.

Caution:

• A heavily scratched face shield
considerably interferes with visibility and
should be replaced if necessary before
riding.

• Stop riding if visibility is poor.

MENU

Outer Shell

Inner Lining

Storing the

Helmet

Use a soft cloth and a small amount of water to
remove bugs from the exterior.

Note: Never use gasoline, diesel fuel, thinners or
solvents to clean the helmet. These substances
can cause serious damage to the helmet, even
though the resulting damage may not be visible.
The full safety function of the helmet can then no
longer be guaranteed.

12.2 Inner Lining

The inner lining of the helmet is completely
removable. Its headliner can be washed by hand
using mild soap at a maximum temperature of 30°C
(86°F). Allow the lining to dry at room temperature.

12.3 Storing the Helmet

Store the helmet in a dry, dark, well-ventilated
location, out of the reach of children and animals.
Always position the helmet so that it cannot fall
to the floor. Damage that occurs in this way is not
covered by the warranty.
