High-performance aerodynamics

 

The C3 Basic is the new generation flip-up helmet. It stands out from the crowd at all times through its advanced aerodynamics and agreeable riding characteristics.

C3 Basic - New generation flip-up technology from the SCHUBERTH wind tunnel makes your next touring journey a sheer riding pleasure.
  • Aerodynamic shape
  • Directionally stable
  • No oscillatory tendency
  • No buffeting

 


Acoustics

Aeroacoustics of the C3 Basic

 

All SCHUBERTH motorcycle and racing helmets are developed and optimised under scientific conditions in the SCHUBERTH wind tunnel. Owing to its outstanding aeroacoustic characteristics, the C3 Basic is the ideal helmet for your touring journeys.
  • Extremely quiet due to integrated acoustic collar and anti-noise pad
  • < = 84 dB(A) at 100 km per hour (with closed machines)
  • Safety principle: the reduced noise level assists the rider's concentration and attentiveness.

 

 


Basics

 

Sound intensity is a phenomenon which can be explained logarithmically/mathematically.

  • A 10 dB(A) jump in noise level is perceived by the human ear as a doubling of the noise level. Conversely a drop of 10 dB(A) is perceived as a halving of the noise level.
  • Physically these changes in the perceived noise level already occur at an increase or decrease of 6 dB (A).
  • This means that the increase/decrease in the physical load is higher than the one perceived.

 


Optimisation

 

Aeroacoustics are influenced by:

  • the position of the helmet in the air flow, depending on the driver's size, riding posture, the motorcycle's fairing
  • The fit of the helmet: differences in the anatomy of the wearer's head, neck and shoulder areas

 

 

Tips

  • change the position of the windscreen
  • close the gap at the bottom of the helmet, e.g. using a scarf

 


Ventilation

Effect

 

The C3 Basic incorporates an effective and powerful ventilation system which enables up to seven litres of fresh air to be supplied per second when travelling at 100 km/h.

 

Equipment features
  • Chin vent
  • Variable pad system
  • Visor vent
  • Air intake

 


Summer and winter

 

The positioning of the pad system can be adjusted, enabling fast and easy adaptation of in-helmet head ventilation according to:

  • the season
  • weather conditions
  • personal preferences

 

 

O2 ventilation

  • In cold weather it often occurs that with closed air supply the motorcyclist's neck zone becomes sealed off by hoods, scarves or neckerchiefs.
  • The concentration of carbon dioxide inside the helmet is a key safety criterion for preventing symptoms of fatigue and the thinning of breathable air.
  • No negative effects on health need be feared as long as the CO2 concentration remains below 3.5 %.
  • The maximum level of CO2 concentration at the workplace is 0.5 %
  • Even when the neck zone is sealed off by hoods, scarves or neckerchiefs, this helmet guarantees that the CO2 concentration remains below the 0.5% limit as from a speed of approx. 30 km/h.
  • In cases where the helmet is completely sealed off by hoods, scarves or neckerchiefs, the visor ought to be opened (city-travel position) for safety reasons when idling, for example at traffic lights, or travelling slowly.
