Alpinestars S-R7 Helmet

Shell:

• Multi-composite combination bonded with an advanced pre-preg epoxy resin process to maximize strength and mechanical performance
• Carbon outer layer, an aramid fiber and a fiberglass layer for a lightweight yet ultra-protective build
• Aerodynamic profile design offers a smooth, streamlined shell free of any external channels that might act as a load point in an impact
• Recess at the collarbone area prevents the shell from coming into contact with the body in a slide, significantly reducing the risk of collarbone injuries
• Three shell sizes: XS-MD, LG, XL-2XL
• Four EPS sizes: XS-SM, MD, LG, XL-2XL
• Integrated road spoiler and lateral winglets devised using wind tunnel testing further reduce turbulence and drag
• Intermediate oval head shape
• Weight: 3lb 7oz (Size MD)

Shield:

• ECE 22.06 homologated optical Class 1 clear face shield included
• Pinlock 120XLT 100% Max Vision Anti-fog lens included
• Shield thickness varies from 1.6mm on the sides to 2.6mm in the center
• Side mechanisms allow the shield to rotate and move to seal it completely against the helmet’s rubber window trim
• Secure and tool-less quick-release system allows the visor to be easily changed or removed
• Shield mechanism is equipped with a premium polymer locking lever to prevent unwanted shield detachment during impacts and can be locked via the frontal metal hook

Ventilation:

• 10 ventilation ports - 6 intake ports and 4 exhaust ports
• Slidable top vent mechanism allows riders to reveal three air channels for maximum cooling performance
• Chin vent features two openings at the sides and a middle ventilation point to channel air towards the inner side of the shield to prevent fogging and misting
• Chin bar extractor vents extract humid air to the outside of the helmet
• Two extractor vents integrated inside the rear spoiler for effective hot air extraction

Interior:

• Unique patented A-Head system allows precise tuning of the helmet’s height and angle to accommodate individual preferences
• Micro-adjustable pad linked to the inner EPS liner enables an ultra-specific setup for head depth and tilt
• All linings are removable, washable and anti-microbial
• Crown pad and neck pad are elastically connected for enhanced oblique impact management
• 3D foam cheek pads have channels for glasses and a channel for hydration tube installation
• Wind curtain and breath deflector included to protect against air entry and prevent shield misting
• Side ear pads improve comfort by reducing aerodynamic noise inside the helmet

Safety:

• Inner shell made in multi-density EPS material with 7 different pieces in six different densities strategically positioned for maximum energy dissipation
• Two Alpinestars patented PLASMA technology collarbone sections integrated into the shell cutaways for high performance shock absorption
• EPS surface features a patented specific coating that acts as a slip plane for proven rotational impact protection
• Equipped with the quick release emergency release system (ERS) fitted as standard
• Exceeds the ECE 22.06 peak rotational acceleration standard by 76%
• Homologated to ECE 22.06 and DOT standards

Other Features:

• Equipped with a 25mm wide nylon chin strap with stainless steel dd rings for a secure fit
• Engineered to be seamlessly integrated with A-Connect Alpinestars communications system (sold separately)

Layered Shell

The S-R7's shell features a carbon outer layer, an aramid fiber and a fiberglass layer. The fiberglass outer layer provides excellent strength and efficient energy dissipation and the unidirectional carbon composite layer provides radial strength around the shell. Aramid fiber and fiberglass layers bolster the other layers with critical penetration protection.

Sleek Safety

The S-R7's aerodynamic profile is free of any external features that might act as a load point in an impact or compromise the helmet's structural integrity. A recess at the collarbone area significantly reduces risk of collarbone injuries by preventing the shell from coming into contact with the body in a slide.

Fine-Tuned Comfort

Alpinestars patented and unique A-Head fitment system allows for a custom, tailor-made fit inside the S-R7. The A-Head system allows you to adjust both the height and angle at which the helmet sits on your head via a micro-adjustable pad that is connected to the helmet inner EPS liner. 

Plentiful Ventilation

The S-R7's ten total ventilation ports work together to deliver optimal airflow. Six intake ports - three in the chin guard and three adjustable top of head vents - are complemented by four exhaust ports located laterally on the chin bar and the rear of the helmet.
