A wide eye port, refined aerodynamics, and efficient ventilation keep vision clear and fatigue low through long stints.\u003c\/p\u003e\n\u003cp\u003eThe GT6 RD ULTRA-4C features the same modern and aggressive design as the HP6 RD-4C revised for racers in closed-car environments, featuring a wide eyeport for extended vision and a lightweight premium carbon glass shell. The closed-face GT6 RD ULTRA-4C integrates the latest technology from ZeroNoise® including advanced electronics, input for earpieces, and noise canceling microphone to assure outstanding performance, sound insulation and communication efficiency.\u003c\/p\u003e\n\u003ch2\u003e4C: Carbon Composite 4 Layer Construction\u003c\/h2\u003e\n\u003cp\u003eOn Bell helmets, “4C” stands for “Carbon Composite 4 Layer Construction.” It refers to the shell technology Bell uses: a four-layer carbon composite laminate. This blend typically combines carbon fiber with other advanced fibers (like Kevlar or fiberglass) in multiple layers.\u003c\/p\u003e\n\u003cp\u003eThe purpose is to deliver a shell that is lighter than fiberglass alone, but more affordable and versatile than Bell’s top-end full carbon HP series shells (like HP7 or HP77, which use pure carbon\/advanced aerospace layups). In this helmet, \"RD-4C” means the helmet is a Carbon Composite 4-layer shell with RD (radio\/drink) kit integration.\u003c\/p\u003e\n\u003ch2\u003eDesigned for GT and Closed-Cockpit Racing\u003c\/h2\u003e\n\u003cp\u003eThe RD configuration includes electronic ear cups and drink-tube routing for clean, reliable comms and hydration in noisy, high-heat cabins. Internal channels manage airflow across the crown and face, and the shell profile is tuned for stability with optional aero accessories.\u003c\/p\u003e\n\u003ch2\u003eBell GT6 RD ULTRA-4C Carbon Fiber SA2025 Helmet Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eManufacturer: Bell Helmets\u003c\/li\u003e\n\u003cli\u003eManufacturer part no.: 123925x\u003c\/li\u003e\n\u003cli\u003eConstruction: lightweight 4C carbon-composite shell\u003c\/li\u003e\n\u003cli\u003eHomologation: Snell SA2025 and FIA 8859-2024\u003c\/li\u003e\n\u003cli\u003eConfiguration: RD (integrated electronic ear cups and hydration routing)\u003c\/li\u003e\n\u003cli\u003eInterior: fire-resistant comfort liner\u003c\/li\u003e\n\u003cli\u003eOrientation: closed-cockpit optimized, wide eyeport\u003c\/li\u003e\n\u003cli\u003eHardware: factory-installed M6 HNR terminals\u003c\/li\u003e\n\u003cli\u003eFinish: gloss carbon-composite\u003c\/li\u003e\n\u003cli\u003eShield: clear shield installed (tinted\/iridium options available separately)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eBell GT6 RD ULTRA-4C Carbon Fiber SA2025 Helmet Key Features\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eUltra-light carbon shell for reduced fatigue and quick head-turn response\u003c\/li\u003e\n\u003cli\u003eEquipped with Bell Racing SmartLock Mechanism\u003c\/li\u003e\n\u003cli\u003eMulti-density, multi-piece liner for impact energy management\u003c\/li\u003e\n\u003cli\u003eIntegrated channels for radio wiring and drink-tube routing\u003c\/li\u003e\n\u003cli\u003eWide eye port for enhanced lateral vision in GT cars\u003c\/li\u003e\n\u003cli\u003eEfficient intake\/extraction paths to promote airflow in warm cabins\u003c\/li\u003e\n\u003cli\u003eCompatible with optional top-forced-air and aero kits (rear spoiler, gurneys)\u003c\/li\u003e\n\u003cli\u003eSealed eye port gasket to help reduce dust and moisture ingress\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch2\u003eBell GT6 RD ULTRA-4C Carbon Fiber SA2025 Helmet Size Chart\u003c\/h2\u003e\n\u003cp\u003e\u003cimg alt=\"Bell GT6 Pro Helmet SA2020 - Competition Motorsport\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0647\/9242\/8763\/files\/Bell_Auto_Racing_helmet-Size_Chart.jpg?v=1762268280\"\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003ca href=\"https:\/\/competitionmotorsport.com\/blogs\/racing-gear-guides\/the-ultimate-auto-racing-helmet-buyers-guide\" title=\"Ultimate Auto Racing Helmet Buyer's Guide\" rel=\"noopener\" target=\"_blank\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0647\/9242\/8763\/files\/HelmetSizingButton_480x480.png?v=1678311769\" alt=\"\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/a\u003e\u003c\/h2\u003e\n\u003ch2\u003eBell GT6 RD ULTRA-4C SA2025 Carbon Fiber Helmet FAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does “RD” mean on this model?\u003c\/strong\u003e\u003cbr\u003eRD indicates the helmet is set up for radio communications and drink-tube routing, with electronic ear cups installed for improved audio clarity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this helmet optimized for closed-cockpit use?\u003c\/strong\u003e\u003cbr\u003eYes.
