Alpinestars Helmets: Where Motorsport Engineering Meets Head Protection

When Alpinestars — a brand synonymous with head-to-toe rider protection — turned its full engineering attention to helmets, the result was a lineup built on decades of motorsport data, wind tunnel development, and direct collaboration with professional racers. Rather than simply putting a logo on a helmet, Alpinestars engineered their own proprietary technologies from the ground up, and the results speak for themselves on tracks and trails worldwide.

The Supertech Family: Purpose-Built for Every Discipline

Alpinestars organizes its helmet lineup around the Supertech platform, with distinct models tailored to road racing and motocross/off-road riding. Popular models like the Supertech R10 and Supertech S-M10 are designed for riders who demand the highest level of aerodynamics, stability, and impact protection on the track or trail.

For road racers, the Supertech R10 is the flagship. Developed over a decade, the Supertech R10 is Alpinestars' most advanced race helmet, designed for ultimate protection, aerodynamic efficiency, and lightweight performance — rigorously tested with MotoGP legends like Andrea Dovizioso, Jorge Martin, and Jack Miller. Developed with CFD simulations, validated in the wind tunnel and on track, the S-R10 helmet is optimized for low drag performance and maximum aerodynamic stability. The Supertech R10 is ECE 22.06, DOT, and FIM certified, exceeding standard impact performance by 37% for linear and 65% for rotational impacts.

On the motocross and off-road side, the Supertech M10 (S-M10) represents the pinnacle of off-road helmet engineering. The helmet's shell construction utilizes a highly advanced molding technology with a multi-composite combination: 3K Carbon high-density outer layer, a uni-directional carbon composite layer, and an aramid fiber layer which provides critical penetration protection. The S-M10 is ultra-ventilated with 28 individual intake and exhaust ports — 18 intakes and 10 exhausts. For direct linear impacts, the SM10 surpasses the ECE 22.06 standard by an average of 46% for regular-speed impacts, and exceeds Peak Linear Acceleration standards by 23% and 28% for low- and high-speed impacts respectively.

For MX riders seeking advanced protection at a more accessible level, the Supertech M5 (S-M5) is a proven choice. The lightweight SM5 features a thermo-injected shell incorporating a special polymer blend with varying degrees of thickness, engineered for an optimal combination of impact protection and light weight, while the five-density EPS liner ensures the correct density in the correct area for enhanced impact absorption.

Signature Technologies That Set Alpinestars Helmets Apart

• A-Head Fitment System: This patented system allows easy adjustment of the angle and height that the helmet sits on the head — a feature that translates directly from the S-M10 to the SR10, letting riders dial in their fit for different riding positions.
• Patented Rotational Impact Management: Alpinestars designed a low-friction surface on the inner surface of the EPS liner — polished smooth and then specially coated to reduce friction even further — allowing the rider's head to move independently inside the helmet, significantly reducing rotational force transmitted to the head, neck, brain, and spine from oblique impacts.
• Collarbone-Protection Chin Bar: The redesigned chin bar profile has been specifically sculpted with a relief section raised to clear the collarbone, with a new softer EPS liner extending beyond the helmet shell itself and covered by a more flexible rubber compound, reducing the chance of collarbone injury.
• Emergency Release System (ERS): The Emergency Release System gives medical personnel a safe and easy way to remove cheek pads while the helmet is still on in the event of a crash.
• MIPS Integration: The Supertech M10 Carbon is fitted with MIPS — an integrated low-friction layer designed to reduce the rotational motion transferred to the brain from angled impacts to the head.

All Full-Face, All Purpose-Built

All Alpinestars helmets are dedicated full-face designs — not modular and without drop-down sun visors. This is a deliberate engineering choice: eliminating modular mechanisms helps maintain the structural integrity of the shell, maximizing impact resistance and ensuring consistent protection in high-speed crashes. Every Alpinestars helmet represents an unwavering dedication to rider safety, backed by 60 years of protecting those who push the limits.
