Stilo AA0822AH1P55 ST6 CMR Carbon Zero Karting Helmet 55cm Small FIA CMR-2016

The Stilo ST6 CMR Carbon Zero is a full carbon fiber youth karting helmet engineered for the next generation of elite competitive drivers. Built from Stilo's highest-grade carbon fiber construction, the ST6 CMR Zero breaks the kilogram barrier at under 1,000 grams — reducing neck fatigue and improving driver focus throughout long race days and multi-heat events. This size 55cm helmet is housed in the compact XS shell, which covers head sizes 53–56cm and reduces overall helmet dimensions by approximately 10% compared to previous generations.

Drawing directly from Stilo's Formula 1 program, the ST6 CMR Zero brings elite-level technology to the karting grid. A redesigned eye-port delivers a significantly wider downward field of vision for improved track awareness and racing precision. F1-inspired top ventilation channels airflow efficiently to maximize cooling and moisture reduction during intense competition.

• FIA CMR-2016 Homologated — Meets all strict international youth karting safety certification requirements
