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 is shortened to a minimum in order to provide enough
fresh air, even in off-road use. The additional wind deflector, when mounted,
prevents unwanted inrush of wind into the helmet while driving. Additionally,
the anti-noise pad can help reduce noise levels in the helmet.
The additional wind deflector is attached to the inside
of the acoustic collar with the help of the Velcro strap,
and it can be removed if desired to let in additional
fresh air in warm 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.
