Homologated to ECE 22.06, DOT, and FIM standards, the S-R10 features a multi-layer composite Carbon shell bonded together with advanced epoxy resin used in carbon car racing chassis to maximize strength, mechanical performance, and weight ratio. Inside the shell is a multi-density EPS liner consisting of eight sections and six different densities for optimal impact absorption and to reduce rotational acceleration, akin to an MIPS system.

Designed for optimal performance and protection, the helmet boasts an optimised chin bar for maximum collarbone protection. The aerodynamically efficient shell includes a recess at the collarbone area to maintain a softer volume upon body contact, and the shell’s lower profile is designed to better protect the rider’s collarbone in a heavy impact.

The Supertech R10 includes two interchangeable open-backed rear spoilers: a short one for the road and a longer version designed for use with leather suit humps, reducing drag by an extra 4.45%. The lateral side wings and a sculpted top visor edge improve streamlined airflow, stabilising the rider’s head in various positions and minimising wind buffeting, fatigue, and neck strain.

The ECE 22.06 visor features an anti-scratch and anti-fog coating, with varying thickness for optical clarity (1.6mm on the sides to 2.6mm in the centre), and pins to attach the included Max Vision Pinlock. Engineered for a cinematic movement, the visor seals perfectly against the shell’s rubber window trim. The shield mechanism features a robust metal lock to secure and prevent the visor from lifting during a crash, complemented by a metal quick-release visor mechanism for maximum strength.

For airflow, the S-R10 features seven passive intake vents: four at the top of the helmet, including a large central slider at the top of the head, two adjustable vents in the chin guard, and a removable rubber bung revealing a third chin vent below the shield lock. To release humidity, the helmet boasts four exhaust vents: two extractor ports on the chin bar and two exhausts under the rear spoiler.

Alpinestars’ patented A-Head System offers a custom, tailor-made fit. Consisting of an interior crown pad adjustable to three stages at the front and back, the A-Head fitment system allows you to alter both the height and angle the helmet sits on your head to your preference for maximum vision.

The soft interior lining is removable and washable for maximum comfort, with interior channels in the cheek pads to accommodate glasses wearers and a hydration tube. With four shell sizes for optimal fit and weight (XS-S, M, L, XL-XXL), this Alpinestars helmet also features emergency release cheek pads, a stainless-steel DD ring-secured helmet strap to enhance safety, and both a clear and dark smoke visor in the box.
