D. THE HELMET
Note:
With faired motorcycles, strong eddy currents occur at the
edges of the wind shadow. These may significantly reduce
the aeroacoustic performance of the helmet. The motorcycle
fairing should be adjusted so that the turbulence created
does not reach the bottom surface of the helmet.

Turbulators
The patented turbulators on the top of the face
shield also optimise the aeroacoustic properties
when riding and prevent acoustic disturbances
in the form of whistling sounds that can be
created by smooth and straight edges.

8. WIND DEFLECTOR
The wind deflector prevents the unpleasant effect of the wind
created as you ride flowing into the helmet. In addition, the
riding noise in the helmet is reduced.
1. The wind deflector is attached
by Velcro strips on the inside of
the acoustic collar and can be
removed when required to provide
an additional flow of fresh air,
especially in hot weather.
Tip:
The fit of the bottom of the helmet is extremely important in
ensuring that the helmet is as quiet as possible. If you have a
smaller neck size, we recommend that you also wear a scarf.
9. CHIN BAR
The C3 is equipped with a chin bar that pivots up and can be
easily opened and closed by means of the operating element
located in the middle of the chin bar. The movement of the
section required for this is optimised for convenient, smooth
operation.
Lock system
The chin section is equipped with a specially developed lock
system on the left and the right side. The construction design
of the lock system is similar to the door lock systems used in car
design. Despite there being locks on both sides, the chin section
opens with only one button. The lock in the opposite side is
simultaneously operated by bowden cable.
