C. THE HELMET

10. RETENTION SYSTEM

The retention system on the SR1 consists of a chinstrap that is
further secured with neckbands at the rear of the shell (anti roll-
off system, see section C.14).
CHIN STRAP WITH DOUBLE-D FASTENING
The double-D fastener lets you adjust the length of the chinstrap
easily and precisely every time you put on the strap and fi ts tightly
and individually to your chin.
Closing and pulling tight
1. Thread the free end of the chinstrap,
as shown in the pictures opposite,
through the double-D fastener.
2. Pull the strap tight. The
chinstrap should be taut but not
uncomfortable. Then feed the free
end of the strap back through the
fi rst ring of the fastener.
Tip: To ensure the correct position we recommend that you
grasp the helmet by the sides with both hands and use
gentle rotating movements on the head, and then pull the
chinstrap tight again.
3. The free end of the strap is tucked
away and fastened by means of
the snap. This prevents the strap
from fl apping in the wind.

Loosening and opening
1. Release the snap and pull on the
little red lug of the double-D
fastener so that the strap is
loosened.
2. Now thread the free end of the
chin strap out of the double-D
fastener.
Warning: Never ride without ensuring that the chin
strap is properly fastened, correctly adjusted and in the
right position. If the chin strap is not properly adjusted or
fastened, it is possible that in the event of an accident the
helmet could come loose from your head.
Warning: Never open the chin strap while riding.

11. VISOR SHIELD

The 3D visor shield, with its average thickness of 2.5 mm, is
manufactured using an injection moulding technique. The special
polycarbonate used has superb transparency, high strength and
toughness, high impact and breaking strength and very good
resistance to weathering. Thanks to the characteristics of its
materials for absorbing UV radiation it also offers effective protection
against UV radiation, which is harmful to human eyes. The shape
and thickness distribution of the visor are the result of many years
of research and development using complex mathematical methods.
The visor sets standards for technical optics: it is almost entirely free
of distortion throughout the fi eld of vision and is rated optical class
1, the highest available quality and a prerequisite for fatigue-free
sight on longer journeys.
