Description

A trusted brand! This motocross helmet is new in Alpinestars range, but in true Alpinestars fashion they've thought of everything! From the outset Alpinestars aimed to create the most advanced, protective and performance enhancing helmet they could. Their primary objective was rider protection whilst they also placed importance on ventilation, comfort and a lighter weight. Drawing on their experienced in motorsports, Alpinestars have ensured that this helmet has: Optimised venting, Multi-Direction Impact Protection System (MIPS), strong peak fitting and can be used in conjunction with a hydration system. Quite simply, if you want something new, from a trusted brand, this is the helmet for all of your off-roading needs.



Manufacturers Specs

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, & providing critical penetration protection
• This combination of layers is given even greater performance with an epoxy resin bonding that offers the best possible strength & energy management; limited outer shell deflection means the energy spreads wider & 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 & oblique impact performance which far improves upon current helmet regulation standard limits. For direct, linear, impact by an average magnitude of 41% & for rotational acceleration, oblique, impact performance by an average of 48%
• The Supertech M8 liner construction combines with the shell to offer highly efficient impact energy management
• S-M8 in four anatomical shell sizes. The Supertech M8 shell construction is optimized to offer best fit across the range of four size options. Shell sizes are manufactured in small, medium, large & 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
• The Supertech M8 liner construction combines with the shell to offer 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 & provides a shape offering a close & comfortable fit
• The 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. Not only is energy performance improved but also fit & comfort
• Patented A-Head fitting height & angle adjustment system
• The Supertech M8 incorportes a patented system to allow the helmet to be tuned exactly to the riders preference for the height & 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 & 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 & also, to tilt the helmet forward, or backwards

KEY FEATURES
• Unique, patented, visor release system is another key attribute incorporated into the design of the Supertech M8
• Visor release is a key part of overall protection performance in the helmet & 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 & 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
• The S-M8 visor release mechanism is conceived to avoid the inherent weaknesses in other types of anchoring systems. Maintaining shell integrity is vital for safety & with the possibility of multi-directional forces impacting on the visor, separation at the critical point of loading reduces potentially damaging leverage & rotational accelerations that refer injury to the rider’s neck & spine
• Ventilation is a key feature of the Supertech M8
• Heat mapping tests have resulted in specifically designed ducting which produces a positive flow into the helmet over & around the rider’s head, improving comfort while riding & 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 & smooth the flow into the shell. The 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 to ensure positive pressure is maintained with constant airflow while riding
• Hydration system compatibility
• The Supertech M8 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 & enduro riders enabling convenient fitting & connection to a hydration system
• Interior lining comfort
• Removable liner cover is washable & features a cool-max fabric interior & anti-bacterial talent yarn for long-lasting freshness & quick-dry performance between riding sessions
• Helmet features TPE coating washable surfaces to improve maintenance & increase durability
• Additional cheek pad set offering increased thickness of +5mm, for tighter fit adjustment – available separately

PROTECTION
• Collarbone protection is an important design feature of the Supertech M8 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 absorbtion pad; a more flexible compound rubber section which allows deflection when it contacts the Clavicle
• The Supertech M8 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 Supertech M8 design, allowing rapid & safe intervention if the rider has suffered a major impact
• Multi-Directional Impact Protection System: MIPS
• MIPS is incorporated into the Supertech 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 M8 helmet, between the comfort padding layer & 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 absorbtion layer to damp & 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)
• The side cheek padding of the S-M8 can be extracted efficiently & safely, while the helmet is still on the rider’s head, to allow ease of removal by trackside support & medical staff
• The Supertech M8 is also designed to allow a helmet ‘Eject’ inflation system to be fitted into the inside crown of the shell
• Along with the ERS padding removal, ‘Eject’ allows for emergency removal of the helmet, without putting load on the rider’s spine
• Chin-strap: Wider than certification requirement: 26 mm for comfort & produced with a woven poly yarn to give a soft ‘hand’ feel that connects securely with a double D-ring
• Weight: Reduced by design while allowing the Supertech M8 protection to be class-leading
• Weight is both a factor in riding performance & safety in a helmet & to ensure the S-M8 offers the ultimate in weight saving performance enhancement, the material selection, preparation & construction of the helmet has been rigorously analysed for weight to strength & energy absorbtion properties & a strict analysis of all the components used in the Supertech M8 finishing
• Weight of S-M8 is 1300g for size Medium (ECE) - 1360g for size Medium (DOT)
• The Supertech M8 Certifications
• The Supertech M8 helmet versions conform to both DOT certification & ECE homologation for use worldwide
• The DOT 218 standard prescribes specific impact penetration protection over the crown of the helmet area & hence, for the US & Canada markets, the Supertech M8 will feature technology that substantially exceedes the minimum safety requirements

Alpinestars Motocross Helmets Size Guide


It is easy to find the helmet size to fit you. Motorcycle helmets should fit snugly on your head even if you have got big hair. Ideally pressure should feel firm and even all over.
Where to Measure To find the right helmet size, measure all the way around your head at the widest part from the front of your forehead right around the back of your head and back to the front again, keep the tape measure above your ears as shown (F) and make sure it feels firm but not overtight or too loose - all measurements in centimetres (CMs).
