Alpinestars Supertech SM-10 Motocross Helmet

The goal behind the Alpinestars Supertech S-M10 helmet range has been simple: to create the most advanced, protective and high-performing helmet in the world. The S-M10 is the result of that ambition – an incredibly lightweight, exceptionally comfortable helmet equipped with top-tier ventilation that never compromises on safety. The aerodynamic, streamlined design of the S-M10 motocross helmet reduces drag and prevents impact forces from concentrating on a single point, delivering maximum protection for your head, neck and spine. The S-M10 is engineered to protect, cool and elevate your riding experience – every single ride.

The outer shell of the Supertech SM-10 is made up of three layers. The outermost shell is constructed from a carbon fibre blend developed exclusively for this product, designed to absorb impact energy more effectively into the material itself and distribute crash forces across a wider area. The second layer consists of a fibre composite that resists crushing while giving the shell flexible properties intended to reduce the forces transmitted to the head. Beneath the outer shell sits an Aramid fibre layer that prevents penetration by external objects. The shells are produced in four different sizes in total, ensuring the correct proportions for every fit.

The inner shell is made from EPS polymer, which absorbs the forces transmitted through the outer shell while providing a firm feel against the helmet’s inner profile. The density and thickness of the polymer shell vary across different areas of the helmet, delivering the best possible fit without compromising on safety.

The interior liner is completely unique and features Alpinestars’ patented “A-HEAD FIT” system, which offers adjustability for a personalised fit. Attached to the inner shell, the system allows adjustments in both height and length. The liner is made from Cool-max fabric, which effectively repels dirt and dries quickly after washing.

The helmet also incorporates the MIPS system (Multi Directional Impact Protection System), which dampens the rotational motion transferred to the brain and slows the sudden stop that is most harmful to the brain in a crash.

The peak is part of the helmet’s extremely effective ventilation system and is also designed to detach from the helmet in the event of an impact. A spare peak is included in the retail package with your purchase.
