Alpinestars S-R7 Kinetis Helmet

Shell:

• Multi-composite combination bonded with an advanced pre-preg epoxy resin process to maximize strength and mechanical performance
• Fiberglass, UD carbon composite and carbon-aramid fiber layers 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 communication system (sold separately)

Outer Shell

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

Aerodynamic Design

The S-R7's aerodynamic shell not only provides an aggressive aesthetic, it's free of any external channels or features that might act as a load point in an impact or compromise the helmet's structural integrity. A recess at the collarbone area prevents the shell from coming into contact with the body in a slide, which significantly reduces risk of collarbone injuries.

Premium Comfort

The unique and patented A-Head fitment system by Alpinestars allows you to adjust both the height and angle at which the helmet sits on your head for the perfect fit! Adjustments are made via a micro-adjustable pad that is connected to the helmet inner EPS liner. 

Optimal Airflow

You'll never lose your cool in the SR-7 thanks to ten total ventilation ports throughout the helmet. 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.
