The Stilo ST6 KRT Composite brings professional-grade performance to adult karting with a full composite shell engineered for strength, stability, and lightweight comfort. Built using Stilo’s advanced multi-layer composite layup, the ST6 KRT delivers outstanding impact protection while maintaining a balanced weight that reduces fatigue over long sessions.
Designed around the proven ST6 platform, the KRT features a wider eyeport for expanded peripheral vision, giving drivers better awareness under high-intensity racing conditions. Its refined ventilation system channels airflow efficiently through the helmet, keeping drivers cool and focused whether they’re turning laps, qualifying, or battling in the final heat.
Inside, performance-driven padding and a carefully shaped shell deliver a secure, stable fit that enhances comfort while minimizing unwanted movement at speed. The streamlined visor mechanism ensures consistent, precise operation and durability across repeated use.
Fully homologated the ST6 KRT Composite is built for adult competitors who demand pro-level protection and reliability. Whether you’re chasing tenths on race day or training hard every weekend, the ST6 KRT Composite offers the safety, vision, and ventilation needed to perform at your best.
