Alpinestars Supertech S-M8 2019 Motocross Helmet - Contact / Orange / Grey

The Alpinestars Supertech S-M8 motocross helmet is the result of over five years of intensive study, development and testing. This motocross helmet has the same technical features as the SM10, the only difference is the outer shell, which is made from fiberglass composite.

Protection

The damping system of the Supertech S-M8 is constructed from 4 layers and the MIPS system. The 4 layers impact protection have different densities, which allows it to dampen all kinds of impacts, from low energy to high energy. The MIPS system ensures damping of rotations. When your helmet hits something at an angle it causes a rotation. The MIPS systems dampens this rotation which helps to reduce the chance of brain injury. Fitment is one of the most impact parts for a protective motocross helmet. The Alpinestars Supertech S-M8 has 4 different shell sizes and 6 total sizes, so you always have a perfect fit. Finally, it is also equipped with a cheek pad emergency system, to easily remove the helmet after a crash.

Performance

Overheating will reduce the performance of a rider, Therefore a ventilation system is an important part of an advanced motocross helmet. The Ventilation of the Alpinestars Supertech is very well executed. The Helmet is no less than 19 ventilation openings at the front. As a result, a lot of fresh air is supplied to the rider. The fresh air flows past the riders head to remove body heat and humid air. The channels inside the Supertech S-M8 are optimized for the best possible airflow. Air can escape through 5 large ventilation holes at the back. The entire ventilation system works seamlessly together to prevent overheating, even in the most intense races. The performance of the Supertech S-M8 is very good. Not only the ventilation system, also the low weight and comfort liner helps the rider perform. You also have the possibility to use a hydration system in the motocross helmet, for this purpose special channels are made within the shell of this Alpinestars motocross helmet.

A-head Head Fitting System

The Alpinestars Supertech S-M8 is equipped with the Patented A-Head fitting system, which is a height and angle adjustment system. It allows the helmet to be tuned exactly to the riders preference for the height and angle at which the helmet sits on the head. This unique technology allows for an ultra-specific set-up that can be adapted for the type of riding and the rider’s preference. With a micro-adjustable pad that is connected to the helmet inner shell, it is possible to raise or lower the helmet fit and also, to tilt the helmet forward, or backwards.

Ventilation

Ventilation is a key feature of the Supertech S-M8. Heat mapping tests have resulted in specifically designed ducting which produces a positive flow into the helmet over and around the rider’s head, improving comfort while riding and reducing the on-set of heat stress in extreme conditions. The visor design of the S-M8 is also an integral part of the ventilation system as it is profiled to direct airflow, acting as a channel to concentrate and smooth the flow into the shell. The Supertech liner design is formed to optimize airflow channeling around the rider’s head before being extracted from the S-M8 through rear exhaust vents to ensure positive pressure is maintained with constant airflow while riding.

Hydration system compatibility

The Supertech helmet lining design includes canals which allow a tube to be incorporated on either side of the shell. This is a feature extensively tested by Alpinestars rally raid and enduro riders enabling convenient fitting and connection to a hydration system.

Interior lining comfort

Removable liner cover is washable and features a cool-max fabric interior and anti-bacterial talent yarn for long-lasting freshness and quick-dry performance between riding sessions.

Chin-Strap

Wider than certification requirement: 26 mm for comfort and produces with a woven poly yarn to give a soft ‘hand’ feel and connects securely with a double D-ring.

Collarbone Protection

Collarbone protection is an important design feature of the Supertech helmet shell base profile.  The base of the S-M8 has been sculpted to give a relief section, where the bottom profile is raised to clear the collarbone (Clavicle). Also, incorporated into the area of the base pad, where it sits over the rider’s collarbone, is an energy absorption pad; a more flexible compound rubber section which allows deflection when it contacts the Clavicle. The Supertech S-M8 chin-bar is formed with polypropylene which, by allowing for a degree of lateral deflection, further improves impact protection for the collarbones.

MIPS

MIPS is incorporated into the Supertech S-M8 to reduce rotational motion energies that impact the helmet causing damaging gyration force to be transmitted to the brain. A low friction ‘slip’ layer is incorporated into the Supertech S-M8 helmet, between the comfort padding layer and the multi-density polymer energy absorption shell. When energy is impacted upon the helmet, causing a rotation force, the MIPS layer allows for movement of the inner absorption layer to damp and re-direct the energy before causing significant acceleration stress to the brain. This mitigates the causes of brain injuries, such as concussion.

Emergency Release System (ERS)

Post-crash protection mechanisms are also a key feature of the Supertech design, allowing rapid and safe intervention if the rider has suffered a major impact. The side cheek padding of the Supertech can be extracted efficiently and safely, while the helmet is still on the rider’s head, to allow ease of removal by trackside support and medical staff. The Supertech S-M8 is also designed to allow a helmet ‘Eject’ inflation system to be fitted into the inside crown of the shell.

ECE and DOT

Conforming to both DOT certification and ECE homologation, the SM-8 is certified for use worldwide.

Shell: Fiberglass

The outer shell of the Alpinestars S-M8 is made of fiberglass composite.
