SCHUBERTH C3 PRO - Aerodynamics; Aeroacoustics

EN
Note:
With faired motorcycles, strong eddy currents occur at the edges of
the wind shadow. These may signicantly 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.

6. AERODYNAMICS
All SCHUBERTH motorcycle and racing helmets are developed and optimi-
sed in SCHUBERTH’s own wind tunnel under precisely dened scientic
conditions. The C3 PRO is specically designed for a touring or sport-touring
riding posture and remains stable in the air current. Even when traveling at
high speeds, the C3 PRO generates practically no upward lift. Enhanced
characteristics of the C3 PRO are improved air resistance and optimised
directional stability. The bueting* on unfaired motorcycles is also signicant-
ly minimised.

Note:
Please note that the strong eddy currents that can occur as a result of
the fairing on faired motorcycles may have a signicant eect on the
aerodynamic characteristics of a helmet.
7. AEROACOUSTICS
Various features developed in SCHUBERTH’s wind tunnel make the helmet
notably quiet as far as aeroacoustics are concerned, while providing optimi-
sed 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.
