Alpinestars S-M8 Features

The Supertech S-M8 is full of advanced features. This is a variant of the top model the S-M10, the only difference between these motocross helmets is the material of the outer shell. The M10 is made of carbon, this M8 version is made of fiberglass. Protection has always been a priority during the development and production of this motocross helmet. This can also be seen in the large amount of protective functions that can be found on this helmet. The most important technical properties are explained below.

A-Head Fitment System

One of the most innovative features is the patented A-head fitment system. With this system the height and angle of the Alpinestars helmet can be adjusted. The A-Head system consists of a micro-adjustable cushion that is connected to the inner shell of the Alpinestars Supertech S-M8. It has 4 places were the position can be changed. By tightening all 4 setup positions, the fit can be made smaller. By adjusting only the rear or front two, the angle can be adjusted. The result is an ultra-specific setup, just as the rider wants it.

Collarbone protection

The bottom of the motocross helmet is raised to prevent contact with the collarbone as much as possible. This specially designed for riders who chose not to wear a neck brace. It is a good feature since collarbone fractures are relatively common in motocross racing. In addition to having a raised area, soft materials have also been applied. Should there still be contact between the collarbone and the motocross helmet, this impact will be damped. In order to preserve the strength of the chinbar, Alpinestars has applied a low weight radial ledge in the chinbar.

Ventilation

Ventilation is an area where Alpinestars has set a new standard. The entire motocross helmet is constructed to improve air flow. The Alpinestars Supertech S-M8 has a very aero dynamical design. Air flow that reaches the front of the helmet is led to the ventilation openings for additional air intake. Even the shape of the peak contributes to better ventilation. In total there are 19 inlet vents that supply fresh air to the rider. Inside the helmet, various channels ensure good flow and cooling where necessary. Hot and humid air is discharged through various large ventilation openings at the back and side of the S-M8.

MIPS

One of the protective features of the S-M8 is MIPS. This system is designed to reduce the risk of brain damage. As soon as an impact hits the helmet at an angle, a rotational movement can occur which can result in high stresses in the brain. This can cause a concussion or worse. To counter this problem, the MIPS system has been developed. It works through a slip layer with low friction that is incorporated in the inner lining. As soon as an impact occurs, the slip layer will begin to rotate. The rotation is then slowed down and damped, which reduces the peak stresses in the brain. The MIPS is placed between the inner lining and the A-head system.

Peak release system

The Alpinestars S-M8 is equipped with a peak release system. As soon as you make a hard impact on the ground, the peak will go off the helmet. This reduces the chance of injury to the neck. An impact on a traditional helmet can cause large stresses on the neck which can be harmful. Alpinestars protects your spine with this release system. The unique design features click tabs that ensure a strong attachment, to prevent accidental releases of the peak. The helmet peak has a fixed position. To change the angle you have two choices. You can mount the extra supplied helmet peak, which has an increased angle. In addition, you can use the A-head system, which allows you to change the angle of the helmet. This is further explained under ‘A-Head Fitment system’.

Hydration system, EJECT and inner lining

Hydration systems are a very important part of many enduro and motocross riders gear. It provides an easy hydration without costing you time. The S-M8 is therefore designed for the use of hydration systems. The drinking tube can be mounted in the cheek parts of the motocross helmet, as shown in the picture above. The canal for a the drinking tube is placed on both sides of the helmet. The S-M8 is also suitable for use with the EJECT system. This is an inflatable cushion that can be place at the top of the helmet. It allows you to safely remove the helmet after a crash. The EJECT and hydration system are not included. The Alpinestars SM8 is equipped with Cool-max lining. This antibacterial material ensures long-lasting freshness and fast drying performance. The inner liner can be removed for easy washing.

Beautiful styling

The design of the S-M8 is the result of performance and strength optimization. Yet the end product is a beautiful motocross helmet that fits perfectly with the style of Alpinestars. It has an aggressive appearance with modern and clean lines. In addition, the designers made beautiful graphic designs that fit perfectly with the rest of the Alpinestars motocross gear collection. Keep an eye on this page because new colors will be released soon. It is available in two price categories. The first one is called the ‘Solid’, this is a single color without a design which is priced lower. The second version are the painted helmets with designs, these are slightly more expensive. To keep the outer surface looking good for longer, Alpinestars has equipped it with a TPE coating. The S-M8 is designed to work with all modern motocross goggles. Large goggles such as the Oakley Airbrake and Scott Prospect also fit in the eyeport.

Protection

This multi-composite motocross helmet is designed to spread impacts over a large area. This allows the EPS lining to absorb the impacts better and thus provide better protection to the rider. The EPS impact damping consists of 4 parts, each with a specific density. Weight is also an important feature for a motocross helmet, both for safety and riding performance. To ensure that the S-M8 has a low weight, there has been a lot of optimization, both in design and production. Alpinestars has achieved an excellent weight to strength ratio with optimum energy absorbing properties. The weight of only 1300 grams is ideal for any competitive motocross or enduro rider. The Alpinestars Supertech S-M8 has been tested at the Alpinestars Racing Development Center. The results show it is much safer than the current requirement for helmet regulations. For direct and linear impacts it scores 41% better, for rotation and angular impacts it is 48% better on average.
