SUOMY SPEEDSTAR Mode D'emploi page 11

The only function of the press stud fitted on the chin strap is to
EN
avoid fluttering of the end part while riding. The fact the press stud
is fastened is no guarantee that the helmet has been positioned
and closed correctly: the correct fastening of the strap must be
verified exclusively through the operations described in the
previous paragraphs.
To release the retention system, unfasten the press stud and pull the
tongue to loosen the closure. Slide out the end part of the strap from
the «D Rings ».
Use the unlocking tongue only to remove the helmet!
Never unlock while riding.
If the retention system does not work correctly, do not use the
helmet and contact Suomy authorized personnel only.

FRONT AIR INTAKE CHIN — A — Figure 3/4
The flow of incoming air in the front part of the helmet (chin)
may be regulated by adjusting on the middle part of the air intake:
- Figure 3: air intake closed.
- Figure 4: air intake fully open.

FRONT AIR INTAKE UPPER — B — Figure 5/6
The flow of incoming air in the upper front part of the helmet
may be regulated by adjusting the middle part of the air intake:
- Figure 5: air intake closed.
- Figure 6: air intake fully open.
FIGURE 4
REAR AIR VENTS — C — Figure 7
The innovative rear air intake has been designed to further improve
ventilation inside the helmet, using residual air flows that, again
thanks to the Venturi effect, are able to generate a depression in
the lower part of the helmet, in this way ensuring a substantial
extraction of the hot air inside it, consequently maintaining a
comfortable temperature.
SIDE AIR INTAKES — D — Figure 7
The fixed air intakes on the sides allow the extraction of air inside
the helmet through the Venturi effect. Their shape has been
designed to optimise this effect and therefore ensure a substantial
extraction of air while maintaining perfect aerodynamic efficiency.
B
The particular shape is also able to reduce turbulence to a
minimum and limit the possibility of the helmet shaking.
