X-804
protection normally used in motorbike sports.
-
Remove the curved fitting from the chin guard lining if you are not using a hydra-
tion system.
-
Do not modify or tamper with the helmet components to install the hydration sys-
tem. Check that the hydration system tube is compatible with the diameter of the
rear port, the tube clamp, the passage channel in the chin guard cover and the
curved fitting.
-
If in doubt or if malfunctions or damage occurs, contact an authorised Nolangroup
dealer.
WIND PROTECTOR AND BREATH DEFLECTOR
(Available as standard or accessory/spare part).
Under certain conditions of use, helmet performance can be improved by using these
accessories.
The Wind Protector reduces unpleasant infiltrations of air under the chin. See Fig.40 for
assembly and disassembly instructions.
The Breath Deflector prevents the formation of condensation on the visor by deflecting
the air flow downwards. It is attached by means of three elastic couplings that must
be inserted into the relevant seats in the front air diffuser. See Fig.41 for assembly and
disassembly instructions.
VENTILATION SYSTEM
The ventilation system of the helmet consists of:
Lower ventilation
It allows ventilation around the mouth area and conveys the air directly on the visor,
thus reducing fogging. See Fig.42 for opening and closing instructions.
Front ventilation
It allows direct ventilation in the front area of the head, even at low speed. See Fig.43
for opening and closing instructions.
Top ventilation
It provides direct ventilation to the head upper area, even at low speed. See Fig.44 for
opening and closing instructions.
Side ventilation
It allows continuous air recirculation in the mouth and visor area (Fig.45).
Rear ventilation
It is integrated in a rear spoiler and allows warm and stale air to flow out, ensuring an
optimum comfort inside the helmet (Fig.46).
RACETRACK AERODYNAMIC SPOILER ( RAS )
The RACETRACK AERODYNAMIC SPOILER (RAS) was developed with the help of offi-
cial Nolan riders using CFD (Computational Fluid Dynamics) studies, before undergoing
extensive wind tunnel testing.
