This XL helmet features a lightweight, multi-layer composite shell made from fiberglass, carbon, and aramid fiber to balance impact protection, force dissipation, sliding performance, energy absorption, stability, and durability. Its aerodynamic profile has a smooth, streamlined surface without external channels that could create load points during an impact. The shell curvature promotes reduced friction and improved deflection, helping transfer energy away from the rider’s head, neck, and spinal column.\u003c\/p\u003e\u003cp\u003eVentilation is provided by 20 individual intake and exhaust ports, including 13 intake ports and 7 exhaust ports, to promote airflow during intense riding. The removable, hand-washable interior uses antimicrobial-treated fabrics, while the adjustable top pad and interchangeable cheek pads allow the fit to be customized. The Alpinestars A-Head system enables height adjustment of the top pad, and replacement cheek pads are available in multiple thicknesses and can be exchanged across shell sizes. The 3D cheek pads include an emergency extraction system and a channel for routing a hydration tube.\u003c\/p\u003e\u003cp\u003eThe SM7 includes Alpinestars’ Visor Detaching System, designed to release the visor when impact energy exceeds 15 joules, helping reduce weaknesses associated with fixed anchoring systems. PLASMA technology is integrated into the lower side pads and shell edge to support energy dissipation in the collarbone area. Additional features include communication-system compatibility with speaker recesses, integrated hydration channels, a 25 mm nylon chin strap with stainless-steel double-D rings, and removable strap covers for washing. The Alpinestars SM7 Core helmet is finished in matte orange and blue, sized XL, and identified by manufacturer and vendor part number 8301826-408-XL.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eComposite Shell: Multi-layer fiberglass, carbon, and aramid fiber construction balances impact protection, energy absorption, durability, and lightweight performance.\u003c\/li\u003e\n\u003cli\u003eOff-Road Racing Design: Aerodynamic shell profile supports smooth airflow and helps reduce friction during impact.\u003c\/li\u003e\n\u003cli\u003eVentilation: Twenty intake and exhaust ports, including 13 intakes and 7 exhausts, promote airflow and rider comfort.\u003c\/li\u003e\n\u003cli\u003eA-Head Fitment: Adjustable top pad allows customized helmet fit and positioning.\u003c\/li\u003e\n\u003cli\u003eInterchangeable Cheek Pads: Removable 3D cheek pads are available in multiple thicknesses and fit across shell sizes.\u003c\/li\u003e\n\u003cli\u003eEmergency Extraction System: Cheek pads include an emergency removal feature for assisted helmet extraction.\u003c\/li\u003e\n\u003cli\u003eVisor Detaching System: Visor is designed to release when subjected to impact energy greater than 15 joules.\u003c\/li\u003e\n\u003cli\u003ePLASMA Technology: Integrated side and lower shell protection supports energy dissipation in the collarbone area.\u003c\/li\u003e\n\u003cli\u003eCommunication Compatible: EPS cutaway and earphone recesses accommodate intercom and speaker installation.\u003c\/li\u003e\n\u003cli\u003eWashable Interior: Removable crown, neck, cheek pad, and chin strap coverings can be hand washed.\u003c\/li\u003e\n\u003cli\u003eHydration Compatibility: Integrated channels support hydration tube routing on both sides.\u003c\/li\u003e\n\u003cli\u003eChin Strap: 25 mm nylon strap with stainless-steel double-D rings provides secure retention.\u003c\/li\u003e\n\u003cli\u003eFitment: XL size with matte orange and blue Core graphics for off-road motorcycle use.\u003c\/li\u003e\n\u003cli\u003ePart Number: Alpinestars manufacturer and vendor part number 8301826-408-XL.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALPINESTARS","offers":[{"title":"Default Title","offer_id":67564228739307,"sku":"01109283","price":519.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/5572707.png?v=1790781492","url":"https:\/\/ctracingservices.com\/products\/alpinestars-sm7-core-off-road-helmet-matte-orange-blue-xl-part-8301826-408-xl","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
