  • Type

    Motocross

    Motocross helmets are specially designed for extreme off-road riding for motocross or enduro races. They have a very long chin and a large visor for protection from the sun or branches.

    They are usually lighter compared to full-face or flip-up helmets to be comfortable for the rider. They are not recommended for riding in the city or on highways.

  • Material

    Thermoplastic

    This is a plastic material mainly used in more affordable and entry-level helmets.

    Thermoplastic shells, such as Polycarbonate or ABS, offer basic protection through deformation upon impact, with greater weight and lower production cost compared to composite materials.

  • Certification

    Certification refers to the official inspection that confirms the helmet meets specific safety standards as defined by international organizations (e.g., ECE, DOT). It is an indication that the helmet has been tested and approved for its ability to protect in real collision conditions.

    ECE 22.06

    New European-type safety specification certification "ECE 22.06", which ensures that the helmet is tested at 18 impact check points instead of 6 as was previously the case. It is now considered the most modern and comprehensive standard for helmet safety in Europe.

    DOT

    Safety standard applicable in the United States. Includes tests for energy absorption, shell strength, and strap retention. It is less stringent than European standards but remains internationally recognized.

  • Pinlock (Anti-fog Film)

    Not Supported

    It is not compatible with the Pinlock system, so it cannot be installed. In this case, the helmet does not have the fittings for adding the Pinlock inner visor, which means there is no special protection against fogging or misting of the visor.

Description & Specifications

Motocross Helmet ALPINESTARS SM3 BLACK-GLOSS

  • Shell construction with a thermo-injected shell incorporating a special polymer blend.
  • Designed for optimal combination of impact protection and low weight.
  • Suitable for MX, Enduro, and Off-Road categories.
  • Innovations and technologies optimized for ease of use, comfort, and impact performance.
  • Low-friction coating that reduces rotational acceleration forces during impacts.
  • Visor release system ensuring correct predetermined release force.
  • Maximum ventilation and high levels of heat exchange with 10 intakes and 7 exhausts.

Shell and protection

The shell is made using thermoforming and a special polymer blend, with variable thickness in different areas. This design has been developed to provide the right balance between impact protection and low weight. The helmet weighs 1,310 g in size Medium according to ECE standards and 1,430 g according to DOT standards.

Inside, multi-density EPS is used, with a different configuration for each helmet size, so that energy absorption is tailored to the areas where it is needed. The inner and outer surfaces are designed to reduce the effects of oblique impacts, while the special construction of the EPS and inner lining helps reduce the rotational acceleration transmitted to the head.

Chin Area Protection

Alpinestars has developed a dedicated testing standard for the chin area of the SM3, with requirements that exceed those of the certification standard. To meet these requirements, both the shell thickness and the helmet structure in the chin area have been optimized to provide enhanced impact protection.

The visor release system features a patented mechanism designed to release the visor when a predetermined force is applied, helping to reduce the forces transferred to the neck during an impact.

Ventilation

The 10 air intakes and 7 exhaust vents ensure increased airflow and effective heat dissipation, helping maintain a comfortable temperature inside the helmet during intense riding.

Comfort and fit

The liner features removable cheek pads and 3D-shaped foam for a comfortable fit. The cheek pads and crown liner are available as genuine replacement parts in different thicknesses, allowing you to tailor the fit to the shape of your head.

The liner is made using recycled materials, helping reduce the product’s environmental footprint.

Practical Functions

The helmet features an Emergency Release System, allowing the cheek pads to be removed safely and easily while the helmet is still being worn. Hydration system tube loops are integrated into the cheek pads for easy access while riding.

The fabric chin strap is 25 mm wide for a secure and comfortable fit, while the stainless steel D-rings ensure a stable and secure closure.

Clasp

Double D Ring

The helmet is fastened with 2 metal rings that the strap passes through between them. 2. It is a mechanism that securely holds the helmet without coming undone. 3. It is not recommended for use with helmets that frequently come off as the fastening requires time. It does not easily break or malfunction compared to the microlock fastening.
