Frequently asked questions Hide FAQs
How does the fit of the S-R7 Solid Helmet work, and how should I choose my size?
The S-R7 Solid Helmet is engineered with a race-oriented full-face shape and Alpinestars’ A-Head Fitment System, which allows micro-adjustment of helmet height and fore-aft angle for a more precise setup. This helps riders fine-tune how deeply the helmet sits and how it aligns in the riding position.
For the best starting point, measure your head circumference and consult the Alpinestars size guide. If you are between sizes, prioritize a secure fit that keeps the helmet stable without pressure points, as the internal fit can then be refined using the A-Head adjustment system.
What safety features and certifications does the S-R7 Solid Helmet have?
The S-R7 Solid Helmet is homologated to ECE 22.06 and DOT standards and uses a pre-preg multi-composite shell combining carbon, aramid fiber, and fiberglass for lightweight strength and impact performance. Inside, the helmet uses a size-specific multi-density EPS liner with seven pieces in six densities to optimize energy absorption.
It also incorporates Alpinestars’ low-friction slip-plane coating to help reduce rotational acceleration in oblique impacts, plus PLASMA inserts in the collarbone recesses to improve shock absorption in key contact areas. Additional protection details include an Emergency Release System in the cheek pads and a secure shield locking mechanism.
Is the S-R7 Solid Helmet good for both track riding and road use?
Yes, the S-R7 Solid Helmet is designed for both track and road riding. Its aerodynamic shell, integrated road spoiler, and lateral winglets are engineered to improve high-speed stability and reduce drag, while the wide eye port supports strong peripheral and vertical vision for situational awareness.
For road use, the helmet balances race-derived performance with daily usability through its ventilation layout, adjustable fit system, and compatibility with A-Connect. This makes the S-R7 a strong option for sport riders who want one helmet for aggressive street riding, fast road work, and track days.
Does the S-R7 Solid Helmet have anti-fog features or work with Pinlock?
Yes, the S-R7 Solid Helmet is Pinlock® compatible. The Optical Class 1 shield includes pins for a Pinlock® 120XLT 100% Max Vision lens, and the shield also features double-sided anti-scratch treatment for durability and optical clarity.
The helmet’s front ventilation system is also designed to help manage misting. Adjustable chin vents and the central chin intake direct airflow toward the inner shield surface to reduce fog buildup in changing temperatures or lower-speed riding conditions.
Is the S-R7 Solid Helmet ready for an Alpinestars communication system?
Yes, the S-R7 Solid Helmet is engineered for seamless integration with A-Connect, Alpinestars’ communication system. This makes the helmet suitable for riders who want to add in-helmet audio and communication without compromising the helmet’s intended fit and aerodynamic design.
The helmet’s interior layout also supports long-distance and performance use with practical details such as removable washable liners, 3D cheek pads with eyewear channels, and an integrated hydration tube channel. These features make the S-R7 particularly versatile for riders who want technical functionality beyond basic protection.
