Crafted with the innovative Premium Integrated Matrix EVO (PIM EVO) construction, this helmet features a shell made from carbon-aramid fiber, carbon fiber, glass fiber, organic non-woven fabric, and natural linen fiber, providing superior shock resistance while maintaining a comfortable weight. Its aerodynamic shape, enhanced by an optimized rear spoiler and shell contour, significantly reduces lift and drag, offering excellent stability at high speeds. The helmet's curved HJ-42 shield, paired with a 2-way pivot ratchet system, minimizes air drag and noise, ensuring clear visibility and a tight seal against the elements for optimal protection and comfort. Pinlock® 120XLT® preparation further enhances fog resistance, making it suitable for varying weather conditions. Designed with rider safety in mind, the helmet includes an emergency pull tab for quick removal in critical situations and an emergency kit with interchangeable cheek pads for a custom fit. The interior features the RPHA Premium Fit lining, with removable, washable, and anti-bacterial fabrics that wick moisture and dry quickly, maintaining freshness during extended wear. Additional features like 3D contour cheek pads, reflective safety material, and fully adjustable ventilation channels promote comfort and safety. The helmet's design emphasizes ease of maintenance and personalization, with interchangeable cheek pads across all sizes and a fully removable interior, ensuring a tailored fit for every rider. Tested in wind tunnels, this helmet guarantees aerodynamic performance and stability, making it ideal for high-speed motorsport enthusiasts seeking a combination of safety, comfort, and performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003ePremium Integrated Matrix EVO (PIM EVO) construction with carbon-aramid fiber, carbon fiber, glass fiber, and organic non-woven fabric for durability and lightweight comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAerodynamic shell design with optimized rear spoiler and shell shape to reduce lift and drag at high speeds\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHJC curved HJ-42 shield with 2-way pivot ratchet system for reduced air drag, noise, and enhanced sealing\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePinlock® 120XLT® prepared lens for fog resistance and clear vision in all weather conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFully removable and washable interior with RPHA Premium Fit lining, featuring anti-bacterial, moisture-wicking, and quick-drying fabrics\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInterchangeable cheek pads for a custom fit across all helmet sizes\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEmergency pull tab and emergency kit with cheek pads for quick removal and safety during emergencies\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdvanced channeling ventilation system for optimal airflow and rider comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReflective safety material for enhanced visibility in low-light conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eWind tunnel tested for aerodynamic efficiency and high-speed stability\u003c\/li\u003e\u003c\/ul\u003e","brand":"HJC","offers":[{"title":"Default Title","offer_id":45192710422723,"sku":"010120051","price":699.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/6052\/2435\/files\/hjc-rpha-12n-helmet-red-bull-austin-gp-ii-small-part-number-fa53nus4f21v-4682160.png?v=1780369644","url":"https:\/\/kellymotorsport.com\/products\/hjc-rpha-12n-helmet-red-bull-austin-gp-ii-small-part-number-fa53nus4f21v","provider":"Kelly Motorsports","version":"1.0","type":"link"}
