Alpinestars Supertech SM8 Motocross Helmet - Radium Red Fluo Black Mid Grey

Supertech S-M8 Helmet by Alpinestars®. The Supertech S-M8 Helmet is constructed of a multi-composite shell and multi-density EPS polymer for for keeping impact energy from reaching your head. Multi-directional Impact Protection System ( MIPS ) reduces slow glancing rotational impact energy that commonly causes concussions on off-road rides. Emergency release cheek pads along with the "Eject" inflation system allow for emergency removal of the helmet with less stress and movement on the spine.

Four shell sizes spread across the XS-2XL size range help keep a low profile and lightweight helmet that fits well. A micro-adjustable pad fine tunes the helmet tilt so you'll have the optimum view out of the eye port no matter what your riding style. Specially designed vents flow air into the helmet around your head to improve comfort when things heat up. Fit a hydration system tube into either side of the helmet to stay hydrated on your next enduro or casual ride.

The Alpinestars S-M8 Helmet is packed full or safety and comfort features, perfect for your single track ride or motocross race.

Construction:

• Shell construction utilizes a highly advanced molding technology with a multi-composite combination
• Uni-directional carbon composite with aramid layer that gives significant radial strength around the shell, preventing compression but allowing controlled deflection for reducing transmitted impact energy, and providing critical penetration protection
• This combination of layers is given even greater performance with an epoxy resin bonding that offers the best possible strength and energy management
• Limited outer shell deflection means the energy spreads wider and is better absorbed by the EPS liner
• The result of the unique shell lay-up process employed in the S-M8 construction results in extremely effective impact protection with a fully equipped helmet testing facility, within Alpinestars Racing Development Center, an exhaustive impact research program has resulted in the Supertech M8 returning linear and oblique impact performance which far improves upon current helmet regulation standard limits

Anatomical Shell Sizes:

• Shell construction is optimized to offer best fit across the range of four size options
• Shell sizes are manufactured in small, medium, large and extra-large to ensure that riders have the correct fit which not only improves comfort but, most importantly, the effectiveness of the helmet in an impact

Highly Efficient Impact Energy Management:

• Formed with a multi-density EPS polymer, the energy absorbing layer gives an inner helmet profile which soaks up impact forces dissipated over the outer shell at the point of an impact and provides a shape offering a close and comfortable fit
• Energy absorption performance of the S-M8 is substantially improved by a four section construction that allows for specific densities of polymer to be prepared for different zones around the helmet lining

Patented A-Head Fitting Height And Angle Adjustment System:

• Patented system to allow the helmet to be tuned exactly to the riders preference for the height and angle at which the helmet sits on the head
• 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

Patented Visor Release System:

• Visor release is a key part of overall protection performance in the helmet and a major influence on the distinctive, flush, design of the outer shell profile
• Alpinestars has developed a unique visor release system which, while ensuring the mounting is held securely in place for riding over the most extreme terrain and any track conditions, provides exactly the right level of resistance to ensure the visor detatches from the helmet shell if it is subjected to a significant impact – no matter what the angle.
• Maintaining shell integrity is vital for safety and with the possibility of multi-directional forces impacting on the visor, separation at the critical point of loading reduces potentially damaging leverage and rotational accelerations that refer injury to the rider’s neck and spine.

Collarbone Protection:

• 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 absorbtion pad (a more flexible compound rubber section which allows deflection when it contacts the Clavicle)
• chin-bar is formed with polypropylene which, by allowing for a degree of lateral deflection, further improves impact protection for the collarbones
• post-crash protection mechanisms are also a key feature of the design, allowing rapid and safe intervention if the rider has suffered a major impact

Multi-Directional Impact Protection System (MIPS):

• Reduces rotational motion energies that impact the helmet causing damaging gyration force to be transmitted to the brain
• Low friction "slip" layer is incorporated into the Supertech M8 helmet - between comfort padding layer and 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 absorbtion layer to damp and re-direct the energy before causing significant acceleration stress to the brain
• Mitigates the causes of brain injuries, such as concussion

Emergency Release System (ERS):

• side cheek padding of the S-M8 can be extracted efficiently and safely, while the helmet is still on the rider’s head
• allows ease of removal by trackside support and medical staff.

Designed to allow a helmet inflation system (Eject) to be fitted into the inside crown of the shell:

• Along with ERS padding removal, "Eject" allows for emergency removal of the helmet, without putting load on the rider’s spine

Chinstrap:

• Offers comfort and safety
• 26 mm wide and thus wider than the certification requirement
• Made of poly yarn
• Conveys comfort and soft skin feeling
• Connects to the double D-ring

Weight:

• Weight of S-M8 is 1300g for size Medium (ECE) - 1360g for size Medium (DOT)
• Material selection, preparation and construction has been rigorously analysed for weight to strength and energy absorbtion properties

Ventilation:

• Developed on heat mapping tests
• 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
• Visor design is also an integral part of the ventilation system - acting as a channel to concentrate and smooth the flow into the shell
• Supertech M8 liner design is formed to optimize airflow channeling around the rider’s head before being extracted from the S-M8 through rear exhaust vents

Hydration System:

• Helmet lining design includes canals which allow a tube to be incorporated on either side of the shell
• Extensively tested by Alpinestars rally raid and enduro riders
• Enabling convenient fitting and connection to a hydration system

Interior Lining:

• Removable liner cover
• Washable
• Features CoolMax fabric interior and anti-bacterial talent yarn for long-lasting freshness and quick-dry performance
• Additional cheek pad set offering increased thickness of +5 mm for tighter fit adjustment (available separately)
