The Stilo ST6 KRT Carbon Kart Helmet is the top-tier option in the ST6 karting range — built specifically for adult competition karting where weight, visibility, and fit directly affect your pace across a full race distance.

Constructed from Stilo's advanced P-Matrix Carbon Fibre lay-up, the shell delivers high impact resistance and structural rigidity at minimum weight. Less mass on your head means less neck fatigue, better balance, and more consistent performance in the closing laps. It meets both FIA 8878-2024 and Snell K2025 homologation standards — the latest certifications required for competitive karting globally.

If you're looking for the composite shell version at a lower price point, see the ST6 KRT Composite.

Key Features

P-Matrix Carbon Fibre Shell — high impact resistance and rigidity at minimum weight, reducing neck strain over long stints
Three shell size system — 54–64cm range uses three outer shell sizes for a closer, more precise fit without unnecessary bulk
Sliding visor mechanism — refined system for smooth, controlled adjustment of the FIA-approved 3mm visor
Enhanced downward field of view — updated eyeport design improves visibility to the kart's front end through braking zones and corner entries
Cheek comfort padding — tailored lateral padding for a secure, stable fit through fast directional changes
Top crown ventilation — multiple vents guide airflow through the interior to manage heat and moisture during intense running
FIA approved 3mm visor — supplied as standard for reliable optical clarity and impact resistance

Homologation

FIA 8878-2024 & Snell K2025 approved. For full technical specifications visit stilo.com.

Size Guide

Sizes available: 54, 55, 56, 57, 58, 59, 61, 63, 64cm. Measure the widest part of your head above the ears. When in doubt, size down — karting helmets should fit firmly.
