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 Supertech M8 Echo MIPS Adult Off-Road Helmets

At the outset of the MX helmet project, Alpinestars product philosophy was applied and a set of specific objectives set: Create the most advanced, protective and performance enhancing helmet possible. Primary objective: protection – to create the most high performance protection possible. Secondary objective: to give excellent ventilation, comfort and reduced weight.

Alpinestars approach to the creation of the advanced technology in the Supertech M8 draws on its depth of experience from over half a decade of world class innovation across the spectrum of motorsports and especially, its deep rooted commitment to motocross. As with all other categories of technology that Alpinestars has mastered, bringing a new, highly complex, product to fruition requires specialist experience and know-how and a project plan led by the best brains in protection development.

Hence Alpinestars Helmet Development Department was created and given the brief to research and develop the most protective and most comfortable possible motocross helmet. The goal was to allow riders to push the limits of performance, benefiting from confidence inspiring safety technology, reduced weight distribution to minimise muscular effort in the neck, shoulders and back and improved physiological and cognitive performance with a supremely well fitting and well ventilated construction, optimizing comfort while riding.

The design is coherent to Alpinestars philosophy and shares distinctive themes with other products in the portfolio; a smooth, attractive, profile which is streamlined and free of any external channels and features that might act as a load point in an impact, or compromise the overall integrity of the construction. The surface curvature promotes reduced friction on impact, allowing deflection and the most efficient transfer of energy to protect the rider's head from direct force to the skull and referred to the neck and spinal column. The aperture is designed to accommodate a wide variety of goggles and the air vents in the shell are located to maximize ventilation efficiency.

The S-M8 shell has been profiled with performance as a priority and with a design style that identifies the profile of the helmet and its sculpted surface as uniquely 'Alpinestars'.

Another key feature is the S-M8 shell sizing solution; each helmet fit size has its own appropriate shell size to deliver the most anatomical solution for the wide variety of fit needs worldwide.

Lightweight outer shell is constructed from technologically advanced composite materials for best fit
Multiple density inner liner
Fitted with E-2, latest generation of MIPS, integrated low-friction layer designed to reduce rotational motion transferred to the brain from angled impacts to the head
Visor attached to the helmet shell with patented system that will allow easy release in case of crash
Adjustable top pad height (Alpinestar's patented A-Head system)
Maximized ventilation with 19 intakes and 5 exhaust ports
Side shell shape coupled with soft EPP foam prevents damage to collarbone in event of crash
Emergency release and removable cheek pads, 3D contoured foam
Removable comfort liner, anti-moisture and anti-bacterial fabrics
Hydration prepared
Colors: Black / Yellow Fluorecent
Sizes: Large, X-Large
