C. THE HELMET
VENTILATION SYSTEM 3 – HEAD
VENTILATION
There is a large air inlet cowl with a three-stage
adjustable ventilation system on the top of the helmet
shell for ventilating the top of your head. Air entering
the helmet through this inlet cowl is directed via
channels to the top of the head. Inside the helmet,
the head padding system enables direct contact
between incoming air and the surface of the head,
thereby conducting the heat away from the inside
of the helmet quickly. The ventilation is adjusted by
means of a slide on the air inlet cowl that is easy to
operate even when wearing gloves. Moving the slide
backwards to the first locking position produces
partial ventilation, moving it further back opens the
air inlet to its full extent.
Summer and winter adjustment
The ventilation of the S2 SPORT can also be adjusted
to suit the seasons, weather conditions or your
personal preferences. While you will prefer the cooling
air current to flow directly on to your head in summer,
in autumn/winter you can reduce the volume of
incoming cold air, or divert it, by covering the
ventilation channels with the head pad. To do so,
raise the middle bar of the head pad slightly and fold
out the fabric flaps located behind the front section.

VENTILATION DEVICE 4 –
INTERIOR AIR EXTRACTION
The S2 SPORT is equipped with an innovative
air extraction system. Fresh air flowing in
through the head vent is directed via the air
channels in the inner shell to the back of the
helmet. The reduced pressure that prevails
at the back of the helmet ensures that the
air is constantly sucked out through the air
vents and special netting material fitted
to the neck pad, thus guaranteeing a
pleasant climate inside the helmet.
VENTILATION DEVICE 5 – MINIMUM
LEVEL OF FRESH AIR
The special shaping of the top of the chin
vent provides the helmet with a guaranteed
minimum ventilation function that ensures a
constant supply of fresh air. The air entering
in this way is regulated so that the rider barely
notices it, but it provides an effective supply
of fresh air from a speed as low as 30 kph
(provided the helmet is positioned fully in the air
flow when travelling). This function counteracts
any build-up of mist on the visor and any excessive
concentration of CO , even when the helmet

is fully closed.
