Designed for young riders seeking thrills, the Supertech M3 Solid motocross helmet offers top-level protection and comfort.

Its anatomically profiled design, specially shaped for children and teenagers, ensures a perfect fit, while its advanced technologies—derived from Alpinestars' adult helmets—provide optimal safety in MX, Enduro, and Off-road riding.

Trust a helmet built to push the limits while ensuring uncompromising protection.

FEATURES :

• This lightweight helmet features a thermo-injected shell incorporating a special polymer blend, optimized with varying thicknesses to achieve the perfect balance between impact protection and lightness.
• The ultra-lightweight outer shell is made from technologically advanced, impact-resistant thermoplastic and is available in three sizes: Youth Small, Youth Medium, and Youth Large. The SM3 Youth weighs 1060 g (ECE) and 1170 g (DOT).
• Distinct versions of the helmet are available to meet DOT and ECE standards. The DOT-certified version features an inner shell reinforced with composite fiber, placed between the outer shell and the EPS liner, ensuring maximum impact protection.
• The fit can be customized thanks to the crown and cheek pads, available in different thicknesses as spare parts.
• The YM and YL sizes share the same EPS size, allowing riders who initially wear a YM helmet to upgrade it to a YL size by replacing the crown and cheek pads.
• The YS size has a smaller EPS liner and can only be adjusted via cheek pads. Alpinestars' extensive research has shown that children wearing YS size helmets are typically 3 to 4 years old, requiring a specially designed fit for their safety and comfort.

PROTECTION :

• NEW ALPINESTARS SAFETY STANDARD
• Alpinestars has introduced a new in-house safety standard for the SM3 Youth, testing the chin bar under more extreme conditions than required by homologation standards. To meet these higher requirements, the shell thickness and helmet design structure have been optimized in the chin area for superior impact protection.
• Equipped with an Emergency Release System and removable cheek pads, allowing for safe and easy removal while the helmet remains on. The 3D contoured foam ensures maximum rider comfort.
• Stainless steel D-rings provide a secure and tight fit.
• The SM3 Youth helmet complies with both DOT certification and ECE 2206 homologation, making it suitable for worldwide use.

CONSTRUCTION :

• The multi-density inner liner ensures that the helmet has the right density in the right areas for enhanced impact absorption, while also contributing to overall weight reduction.
• The inner and outer surfaces are designed to minimize the effects of oblique impacts.
• Alpinestars’ patented low-friction coating is applied to the inner part of the EPS liner to reduce rotational acceleration forces caused by certain oblique impacts. This layer acts as a slip plane, mimicking the brain’s cerebrospinal fluid, which naturally protects against oblique impacts.
• Optimized ventilation with 10 air inlets and 7 exhaust ports, ensuring high levels of heat dissipation.
• The visor is designed to direct airflow into the ventilation ports, improving internal airflow.
• Patented visor release system ensures that the visor detaches with a pre-determined force, reducing stress on the rider’s neck in the event of an impact.
• The comfort liner is made from recycled materials, contributing to a lower carbon footprint.
• Integrated hydration tube channels in the cheek pads provide added convenience and performance.
• The 25 mm soft textile chin strap ensures optimal safety and rider comfort.
