Alpinestars are renowned for their off-road kit, and their motocross helmets are no exception. The Alpinestars Supertech SM-8 helmet offers a multi-composite combination with advanced moulding technology. This combination of layers gives even more outstanding 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. Each size of the SM-8 has its own individual shell size for superior aerodynamics and weight efficiency. 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. For direct, linear, impact by an average magnitude of 41% and for rotational acceleration, oblique impact performance by an average of 48%. Not only does the Supertech SM-8 helmet offer outstanding impact protection, but it also looks fantastic! The aggressively styled shell offers superior aerodynamics and features classic Alpinestars styling. The ventilation system boasts maximum airflow for optimum comfort with a removable and washable inner liner to keep you fresh. Available in a choice of stylish colours. The S-M8 also offers Alpinestar's patented A-Head fitting height and angle adjustment system for the perfect fit. With a micro-adjustable pad connected to the helmet's inner shell, it is possible to raise or lower the helmet fit and tilt it forward or backwards. 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 detaches from the helmet shell if it is subjected to a significant impact – no matter what the angle. The S-M8 is also hydration system compatible. The Supertech M8 helmet lining design includes canals which allow a tube to be incorporated on either side of the shell. The removable inner liner is washable and offers a Cool-Max fabric interior for long-lasting freshness and quick-dry performance. 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 S-M8 chin-bar is formed with polypropylene, further improving the collarbones' impact protection. It features a Multi-Directional Impact Protection System: MIPS to reduce rotational motion energies that impact the helmet, causing damaging gyration force to be transmitted to the brain. Alpinestars' Emergency Release System (ERS) means the side cheek padding of the S-M8 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 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 the emergency removal of the helmet without putting pressure on the rider’s spine. The chin strap is wider than the certification requirement: 26 mm for comfort and produced with a woven poly yarn to give a soft ‘hand’ feel that connects securely with a double D-ring. It weighs an ultra-lightweight 1300g for size Medium (ECE). Other colours and graphics are also available.
