D. THE HELMET

6. AERODYNAMICS

All SCHUBERTH motorcycle and racing helmets are developed and
optimised in SCHUBERTH's own wind tunnel under scientifi c, precisely
defi ned conditions.
The S1 PRO is specifi cally designed for a sporty riding posture and
remains stable in the air current. Even when travelling at speeds above
200 kph, the S1 PRO generates practically no upward lift. Further
characteristic features of the S1 PRO are improved air resistance,
excellent directional stability and minimal lateral forces. In addition, the
buffeting often experienced at high speed is signifi cantly reduced for
unfaired motorcycles.
Note:
Please note that the strong eddy currents that can occur at the
edges of the wind shadow on faired motorcycles owing to the
body panels can have a considerable effect on the aerodynamic
characteristics of a helmet.

7. AEROACOUSTICS

Various measures developed in SCHUBERTH's wind tunnel ensure
an aeroacoustically comfortable helmet* with optimised acoustic
feedback while travelling. This enables enhanced concentration,
especially at speeds in the upper ranges.
* Aeroacoustic values can vary according to the type of motorcycle, bodywork design,
riding position and body size.
Note:
Please note that on faired motorcycles strong eddy currents
occur at the edges of the wind shadow. This can considerably
reduce the aeroacoustic performance of the helmet. The fairing
of the motorcycle should be adjusted so that the departing
turbulence does not strike the bottom surface of the helmet.

Aeroacoustically non-critical area
Tip:
To ensure the helmet is as quiet as possible, the fi t on the
underside of the helmet is extremely important. This area needs
to be well sealed off. If you have a narrow neck, it is advisable to
use a scarf.
ANTI-NOISE PAD (included)
With the help of the supplied Anti-Noise-Pad, noise
in the helmet can be further reduced. The pad is
fi tted in a few easy steps.
1. Insert the rounded end of the Anti-Noise-Pad
under the lip of the wind defl ector.
2. Slip the outer edge of the Anti-Noise-Pad step-
by-step under the lip of the wind defl ector.
3. Feed the second insertion tab with gentle
pressure under the lip of the wind defl ector.
