One Goal. One Vision

Alpinestars is once again leading the way in developing rider safety. Having pioneered countless innovations in boots, suits and gloves, notably the development of external protection on road race boots in the early 80’s and more recently employing the philosophy on its leather suits, they are now introducing a new dimension into race suit technology – a fully autonomous, multiple field data acquisition system. The Advanced Safety Technology suit (AST).

Fitting telemetry and acquiring data from race bikes and cars has been common practice for some years, however, acquiring data directly from the body of the rider/driver has not and Alpinestars is developing technology to allow technicians the ability to analyze the gravitational and impact forces, as well as the physiological effects experienced by a human when pushing the limits of a high performance race machine.

During the weekend of the German Grand Prix at the Sachsenring, MotoGP rider John Hopkins wore a leather suit equipped with the new A.S.T. system. Although indistinguishable from his usual race suit, John’s body was constantly monitored by a series of accelerometers, impact and physiological sensors.

The impact sensors are mounted on both external and internal surfaces of the suits protectors to measure the loads sustained and absorbed in a fall, without impeding or endangering the rider in any way. The sensors record the maximum impact value subjected to the rider, providing real situation data, above and beyond the test simulations currently conducted in the Alpinestars laboratory.

The custom data processor and solid-state memory, encased in an impact resistant structure and hidden in the back hump on John’s suit, acquire data throughout each session which can be downloaded immediately into a laptop plugged into a connector on the suit. The information can then be studied to analyze pressure point values, lateral G loads experienced, the rider’s pulse and the suit’s cooling performance.

The benefit of developing such technology is the tremendous amount of information that can be gathered about the stresses borne by a rider and the performance of safety equipment during a race and in the event of a fall. Alpinestars’ goal is to develop the technology to measure all the dimensional forces at work upon a rider and to allow greater understanding of material performance thereby improving safety both on the racetrack and ultimately on the road.

Alpinestars S-M7 Cast Adult Off-Road Helmets

The S-M7 Helmet is engineered for off-road racing, and is optimized to offer the perfect blend of superior ventilation and comfort in a lightweight helmet, while its supremely aerodynamic composite shell delivers exceptional impact protection. In addition to Alpinestars' patented A-Head Fitment and Visor Detaching Systems, the S-M7 is equipped with innovative PLASMA technology at the lower side of the shell edge for optimum energy dissipation in case of contact with the collarbone area.

Aerodynamic Design: The S-M7's aerodynamic profile design offers a smooth, streamlined shell free of any external channels and features that might act as a load point in an impact or compromise the overall integrity of the helmet's construction
Energy-Deflecting Design: The helmet's curved shell is engineered to reduce friction and deflect impact forces away from the head, helping protect the skull, neck, and spine in the event of a crash
PLASMA Inside: Alpinestars' PLASMA technology is strategically-integrated into the S-M7's side pads for high performance shock absorption in a critical area, significantly reducing the risk of injuries
A-Head Technology: Alpinestars patented A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head for an optimized performance fit
Inner Shell Linear and Rotational Impact Protection: The inner shell is made in multi-density EPS material to permit the required impact absorption properties exactly where they are required. The EPS liner, just like the outer shell, has its own unique dimension for each helmet size. Specific rotational impact protection is provided by the combination of the internal shape and specific coating of the EPS liner, coupled to a specially-developed surface in the comfort liner. This patented technology reduces rotational acceleration transmitted to the rider's head
Patented Visor Release: The S-M7's patented Visor Release System is designed to detach during a crash, reducing the risk of helmet damage or rotational injury
The S-M7's visor is engineered to automatically detach from the shell when it is subjected to an impact energy greater than 15 Joules for optimum impact protection, regardless of the direction
Shell Sizing for Optimal Fit: The S-M7 shell sizing solution ensures each helmet fit size delivers the most anatomical solution for the wide variety of fit needs worldwide, providing 3 different helmet shell sizes and 6 consumer sizes from XS to XXL to ensure riders have the correct fit which not only improves comfort and reduces overall weight, but most importantly, improves the effectiveness of the helmet in an impact
Hydration System Ready: The helmet incorporates integrated channels on both sides to accommodate a hydration system
The helmet's shell construction utilizes a highly advanced molding technology with a pre-preg composite construction that delivers enhanced mechanical performance with an ultra-light overall weight
The result of the unique shell lay-up process employed in the S-M7 construction results in extremely effective impact protection. The S-M7 returning linear and oblique impact performance significantly exceeds current helmet regulation standard limits
Specific rotational impact protection is provided by the combination of the internal shape and specific coating of the EPS liner, coupled to a specially-developed surface in the comfort liner. This Alpinestars Patented Specific Coating technology reduces rotational acceleration transmitted to the rider's head: the S-M7 Helmet exceeds the new ECE 22.06 Peak Rotational Acceleration standard by 76%
Profiled chin bar for proven impact protection
The S-M7 is available in two homologated versions with ECE 22.06 and DOT certification
Multi-layer shell is constructed from a blend of fiberglass, carbon, and Aramid fiber for the optimum blend of impact protection and force dissipation, sliding performance, energy absorption, stability and durability
Patented A-Head Fitment System allows easy adjustment of the angle and height that the helmet sits on the head
Ultra-ventilated helmet with 20 individual intake and exhaust ports, not including the eye port, with 13 intakes and 7 exhausts, for optimum ventilation
Eject Removal System Ready: the helmet is designed to accomodate the installation of an eject removal system, which includes a removable insert on top of the EPS
Removable Lining: With a 3D foam for optimum comfort, the lining features an anti-microbial treatment for long-lasting freshness
The S-M7's fit can be further customized via the Alpinestars genuine replacement cheek pads, which are available in all thicknesses, and are exchangeable between all shell sizes
Communication System Ready: Pre-equipped with ear recesses designed to accommodate communication systems
Lightweight: ECE 1280g and DOT 1340g for a size medium
The S-M7 Solid is available in two homologated versions with ECE 22.06 and DOT certification
Colors: Red / Yellow Fluo / Blue Glossy
Sizes: Small, Medium, Large, X-Large, 2X-Large
