Combining a multi-composite shell with Alpinestars’ patented PLASMA technology, the S-R7 is designed to provide a high level of impact protection while maintaining a lightweight construction.\u003c\/p\u003e\n\u003cp\u003eThe multi-composite shell combines carbon, aramid fibre and fibreglass with pre-preg epoxy resin to deliver strength, energy dissipation and penetration resistance. Inside, a size-specific EPS liner uses seven pieces across six densities, precisely matched to each shell size for optimised impact absorption. Alpinestars’ low-friction slip plane is incorporated into the EPS to help reduce rotational acceleration during oblique impacts, while PLASMA inserts in the collarbone recesses are designed to provide additional shock absorption during a slide.\u003c\/p\u003e\n\u003cp\u003eAerodynamic performance is a key feature of the S-R7, with the shell, integrated road spoiler and lateral winglets developed to reduce drag and turbulence while supporting high-speed stability. The 10-port ventilation system uses six intake and four exhaust ports, while adjustable chin vents, a central chin intake, sliding top vent and rear extractors help maintain airflow throughout the helmet. The removable and washable comfort lining features anti-microbial fabric treatment, while 3D cheek pads include eyewear channels, an Emergency Release System and hydration tube channel.\u003c\/p\u003e\n\u003cp\u003eThe ECE 22.06 homologated helmet is equipped with an Optical Class 1 anti-scratch shield and is Pinlock 120XLT 100% Max Vision compatible. Its secure locking mechanism and tool-less visor release provide practical functionality, while the A-Head Fitment System allows micro-adjustment of helmet height, depth and fore-aft angle for a more personalised fit.\u003c\/p\u003e\n\u003cp\u003eThe S-R7 is also engineered for seamless integration with the \u003ca href=\"\/products\/alpinestars-a-connect-communication-system\" title=\"Alpinestars A-Connect Communication System\"\u003eAlpinestars A-Connect Communication System\u003c\/a\u003e, featuring a second-generation Harman Kardon sound system with 40mm speakers and AI-based noise cancellation technology. Finished in bold Lumen Black \/ Purple \/ Red \/ White Glossy, the Alpinestars S-R7 combines sophisticated protection technology with race-inspired aerodynamic performance for riders demanding advanced helmet technology on the road or track.\u003c\/p\u003e\n\u003ch5\u003eFEATURES\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eKEY
