Aerodynamics

 

High-performance aerodynamics

The S2 is specially designed for a sport touring riding position to remain stable in the air flow. The special shape of the helmet shell and the full circumference spoiler along the rim of the helmet ensure enhanced down force. The S2 creates practically no upward lift, even at higher speeds. In addition, the S2 also offers high directional stability. The buffeting is also significantly reduced on naked bikes. 

  •  Perfected aerodynamics 
  •  Upward lift = 0!
  •  Directionally stable
  •  No oscillating
  •  No buffeting

Acoustics

 

Aeroacoustics of the S2

A quiet helmet means active safety for the motorcyclist: this permits the rider to concentrate on riding – particularly at higher speeds. 

Many hours in the Schuberth acoustic wind tunnel have ensured that the S2 is exceptionally quiet. The comprehensive acoustics package with optimized helmet shell, wind deflector and ergonomic shape of the neck padding make the S2 – at 85 dBA – one of the quietest helmets of all

  • Aero-acoustics optimization for a helmet quiet
  •  Installation of a wind deflector enables the aeroacoustics and consequently the noise level to be improved still further.
  •  Only 85dB(A) at 60 mph (with naked bikes)

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 and riding posture and the motorcycle's fairing
  • Fit of the helmet: differences in the anatomy of the wearer's head, neck and shoulder areas

Tips

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

Ventilation

 

Innovative ventilation system

The S2 is equipped with an innovative Air Extraction System. The combination of multipath channels in the EPS foam liner and the head, chin and mouth ventilation ensure that fresh air is distributed efficiently throughout the entire head area. The fresh air which enters via the forehead ventilation is conducted through the inner shell's air channels well beyond the back of the head to the rear of the helmet. The low pressure prevailing at the rear of the helmet creates a siphon effect causing the interior air to be pulled in and extracted constantly through the air outlets and the special mesh fabric in the neck padding

  • Head ventilation input (adjustable in multiple stages)
  • Chin vent for targeted distribution of the incoming air in the helmet
 

Effect

The S2's powerful ventilation system 

  • Chin vent
  • Variable pad system
  • Face  shield vent
  • Adjustable top vent
  • Active Air Extraction System
  • EPS shell with ventilation channels
 

O2 ventilation

  • In cold weather a helmet is sometimes sealed closed by sealed off by hoods, scarves or neckerchiefs locking out the fresh air supply.
  • 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 face shield ought to be opened (city-travel position) for safety reasons when idling, for example at traffic lights, or travelling slowly.

 

 

 

SRC-System™-ready

The S2 is by default equipped to accommodate the SCHUBERTH SRC-System™ S2. To guarantee ideal radio reception for you, the S2 is already equipped with two integrated
antennas to boost reception and a Bluetooth® connection

  • Optimum reception quality at all times 
  • Bluetooth® antenna for wireless mobile, navigation and intercom connections to other SRC-System™ owners
 
 

In detail

The helmet

  •  

Outer shell

The outer shell of the S2 comes in two helmet shell sizes for optimum fit, combining an aerodynamically optimal shape with excellent protection. It is manufactured using Schuberth's proprietary compression molding process resulting in exceptional stability and a light weight.

  • Shell material: S.T.R.O.N.G. fiber
  • Helmet shell technology from SCHUBERTH results in low weight
  • Pre-woven glass fiber material is compressed with a special resin in a high pressure heated vacuum mold to form the helmet shell which is exceptionally sturdy.
  •  

Inner shell

The protective layer of special EPS foam is injection molded into a single multi-density piece to ensure optimal shock absorption. This complex segmentation guarantees enhanced force absorption and distribution to maximize safety. 

  • Made of specially optimized EPS foam
  • Complex multizone foaming allows optimal shock absorption
  •  

Comfort Liner

The special inner lining of the S2 was developed according to the innovative Comfort Fit concept to ensure that the helmet fits comfortably and securely in all situations.

The combination of carefully selected COOLMAX® and Thermocool® materials and the additional use of Interpower® coatings also make the inner lining a highly-effective moisture wicking and cooling system

  • COOLMAX® lining, completely removable and washable (hand wash, 80°F)
  • Optimized fit
  •  Variable for effective ventilation
  •  Adjustable for summer/winter conditions
  • Hypo-allergenic
  • Antibacterial
  • Removable comfort cheek pads and crown liner
  •  

Fastener system

  • Precise setting of the chinstrap length through adjustment on both sides.
  • Micro-lock ratchet lock
  •  

Reflective Materials

The silver-colored appliqués of reflective material on the neck collar of every SCHUBERTH helmet ensure that the motorcyclist can be seen better, especially in twilight or at night. 

  • Improved visibility = Enhanced safety
  • Enhancement of the passive safety
  • Early recognition by other road users 
  •  

Face Shield

  • Injection molded for optimal clarity. 
  • Patented “turbulators” break up windflow to eliminate noise.

Safety

Anti-Roll-Off-System

  •  

A.R.O.S.

The Anti-Roll-Off System (A.R.O.S.) especially developed and patented by SCHUBERTH is provided as a safety feature in every SCHUBERTH motorcycle helmet. It ensures that provided the chinstrap is closed and correctly adjusted: 

  • the helmet cannot pivot off the head from behind
  • the risk of contact between the chin section of the helmet and the chin or throat of the rider is minimised due to the small angle of tilt and
  • the consequences of the helmet coming into contact with the chest as the result of an accident are reduced.

The helmet also has Reflective areas which improve visibility in the dark and thus contribute to your safety.
