Urban position
In its second locking position, the face shield is automatically in urban position.
Air entering through the bottom gap ows over the inside of the face shield and
escapes through the opening at the top.
VENTILATION DEVICE 2 – INLET VENT IN CHIN AREA
(face shield ventilation)
The C4 BASIC features an air inlet in the chin
section for visor ventilation. Air ows through
the open air inlet regardless of riding position. A
deector ensures that the air current ventilates
the face shield eectively even at low road
speeds. Press on the ventilation unit to open or
close the air inlet.
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 rst locking position produces partial
ventilation, moving it further back opens the air
inlet to its full extent.
