The outer shell of the S1 PRO is offered in two helmet shell sizes and combines an aerodynamically optimal shape suitable for racing with excellent protection.

• Shell material: S.T.R.O.N.G. fibre and carbon
• Special glass fibre reinforced special duroplast matrix
• New helmet shell technology from SCHUBERTH permits low weight
• Glass fibre with a special resin added is compressed in a vacuum at a pressure of 4.5 bar to form a helmet shell which is exceptionally sturdy.
• Weight of the shell: approx. 500 grams

Improved visibility = Enhanced safety in the dark

• Reflex eyes under the visor (to retain the usability)
• Reflex pads embedded in the neck padding

• The EasyChange visor mechanism makes changing visors extremely simple and quick.
• City position of visor

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.

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

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

The S1 has an innovative ventilation and extraction system.

• Effective visor ventilation via ventilation inlets (adjustable) in the chin area
• Three sport ventilation inlets (adjustable) for effective head ventilation
• Air extraction via material in the neck protection area and ventilation outlets on the top of the helmet

The effective and efficient ventilation system of the S1 PRO

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

• 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, the S1 PRO 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.

The Anti-Roll-Off System (A.R.O.S.) especially developed 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 neck of the rider is minimised due to the small angle of tilt
• the consequences of the helmet coming into contact with the chest as the result of an accident are reduced

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