The Alpinestars S-R7 helmet takes many of the features from it's bigger brother the S-R10, a helmet that changed the high end race/sports bike market on it's head and made it a real option to be able to choose more than a Arai or Shoei.. The S-R7 is a more user friendly version and the first to be pre-built for a top of the range Sena unit which Alpinestars call A-Connect.
