C. THE HELMET

6. AERODYNAMICS

The AVENTURO Mod is designed especially for the touring riding po-
sition and does not move around in the airflow. Even at higher speeds,
the AVENTURO Mod generates almost no lift. Additional features of the
AVENTURO Mod include improved air resistance and directional stabili-
ty. Buffeting* is significantly reduced on standard motorcycles as well.
* Shaking of the helmet as the air flows around it.
Note:
Please note that the strong eddy currents that can occur as a result
of the fairing on faired motorcycles may have a significant effect on
the aerodynamic characteristics of a helmet.

7. AEROACOUSTICS

Various features developed in SCHUBERTH's wind tunnel make the hel-
met notably quiet as far as aeroacoustics are concerned, while providing
optimised hearing capability when riding. This enhances concentration,
especially at high speeds.
Note:
Aeroacoustic values may vary according to the type of motorcycle,
fairing design, seat position and physical size of the rider.
Caution:
As a result of the aeroacoustic optimisation of the helmet (and the
lower wind noise inside the helmet that comes with it), your actual
speed can easily be underestimated. Please do not rely on your
sense of hearing to estimate your road speed - always check it
using your speedometer.

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..
