The EvoLine
offer you the greatest pleasure in use.
The profile of the helmet, its impermeability
and the quality of the materials used enable air
noise on the crown of the head and aerodyna-
mic turbulence to be filtered as far as possible.
In order for the use of your helmet to be as
pleasant as possible, it is important for tur-
bulence or air eddies created by the fairings
not to impair the aerodynamic qualities of your
EvoLine helmet. The shape of the fairings of
®
your motorcycle and/or your size should not
cause air eddies to reach the lower part of
your helmet.

ThE VIsor

The visor on your helmet is injected using a
specific polycarbonate material developed for
the excellence of its optical qualities and its
high quality performance in resisting shocks.
Your visor is certified Total Vision. Its external
surface is treated to give high resistance to
scratches. The specific treatment applied to
its internal surface limits as far as possible the
risk of misting.
In order to prolong the life of these two treat-
ments as far as possible, you have to look after
your visor carefully.
When you clean your visor, leave it to soak in
tepid water (less than 40 degrees) and use a
soft cloth (100% cotton that does not pill) to
dry it. A little "neutral" soap (like household
soap) may help you to clean it.
warnInG! do not use window clea-
ning type products (based on alcohol
or other types of solvent) as these products
may damage the visor's treatments.
The anti-scratch and antifog treatments are
active and their action may vary under atmos-
pheric conditions and under heavy rain.

Under difficult conditions, surface treatments
take time to recover their effectiveness; we
therefore advise you to put your helmet or the
visor in a dry, well ventilated place so that it
recovers its effectiveness.
In either the Integral or Jet position, the visor is
adjusted using the catch on the upper central
part of the visor.
In the Integral configuration, you have the
possibility of riding with the visor slightly open
(Figs. A – B);
Because of its original axis of rotation, the
visor remains close to the crown, thus avoi-
ding excessive aerodynamic resistance in the
open position.
