Alpinestars S-R7 Kinetis Helmet

Description

Alpinestars S-R7 Kinetis Helmet

Sizing: 

• Riders find the S-R7 fits small
  • Consider moving up 1 size from what the Alpinestars size chart recommends

Shell:

• Similar in shape and ethos to the top-tier SR10 track helmet but tuned for upright field of vision and aero
• Smaller rear spoiler size for improved road comfort but still packs plenty of race DNA to get you on the track
• Integrated comm door integration at the side is very clean for smooth, touring aero
• 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)
