D. THE HELMET
Ventilation device 2 – inlet vent in chin area
(face shield ventilation)
To ventilate the face shield, the S2
is provided with an inlet in the chin
area. Irrespective of riding posture,
around 80-90% of the central
airstream flows directly into this
inlet when open. A deflector ensures
that the air current ventilates the face
shield effectively even at low road
speeds. You can open and close the
inlet by pushing the vent upwards or
downwards.
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 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 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.
