Stilo AA0822AH1P53 ST6 CMR Carbon Zero Youth Karting Helmet Size 53 XX-Small

The Stilo ST6 CMR Carbon Zero is a top-of-the-range, full carbon fiber youth karting helmet engineered to deliver the ultimate combination of lightweight performance and FIA-certified protection. Purpose-built for competitive young drivers, this helmet brings Formula 1-inspired technology directly to the karting grid in a size 53 cm (XX-Small) fitment.

Ultra-Lightweight Full Carbon Construction

Constructed entirely from full carbon fiber, the ST6 CMR Carbon Zero tips the scales at under 1,000 grams — making it one of the lightest FIA CMR-2016 certified helmets available. The reduced weight directly translates to less neck strain and improved driver comfort during extended race sessions, without any compromise to structural protection.

New Compact Shell Design

The size 53 cm falls within Stilo's new XS shell, which accommodates head sizes 53–56 cm. This new shell reduces overall helmet dimensions by approximately 10% compared to previous generations, improving aerodynamics and ensuring a more tailored, race-ready fit for smaller head sizes. Notably, size 53 is offered for the first time in the ST6 CMR lineup.

Formula 1-Inspired Ventilation

An advanced airflow system derived directly from Stilo's Formula 1 program features strategically placed front and top vents designed to maximize cooling and reduce moisture buildup during high-intensity racing conditions.

Expanded Field of Vision

The ST6 platform introduces a wider eyeport with a noticeably improved downward field of view compared to the previous ST5 model, enhancing driver awareness, precision, and confidence on track.

Rigorous Safety Standards

Fully homologated to FIA CMR-2016 standards, the ST6 CMR Carbon Zero is legal for use in all youth karting competitions requiring CMR certification. The helmet features a 3mm thick, injection-molded visor that is double-glazed, anti-fog, and washable. The innovative visor locking system ensures maximum security in both open and closed positions. Upgraded interior padding and a redesigned crown area deliver a secure, comfortable fit during high-speed cornering.
