Stilo ST6 CMR Zero Carbon Kart Helmet

If you want the absolute best kart helmet available — the lightest shell, the highest-grade carbon, and a certification that meets the most demanding standards — this is it. The Stilo ST6 CMR Zero Carbon weighs just 970g. That is exceptional. Full carbon fibre construction, Snell-FIA CMR 2016 certified, with an FIA approved 3mm anti-fog visor as standard. Built on Stilo's flagship ST6 platform — the same platform trusted by professional racing drivers worldwide.

This is not a budget kart helmet. This is the pinnacle of what a CMR-class kart helmet can be.

⚠ Interior lining colours: Black (standard) is available for immediate dispatch. All other interior lining colours are special order — please contact us before ordering to confirm availability and current delivery lead times.

Why the ST6 CMR Zero Stands Apart

• 970g — one of the lightest CMR kart helmets available — less weight on your neck means less fatigue, better head movement, and faster reactions over a full race distance
• Full carbon fibre shell — not composite, not fibreglass — pure carbon, delivering maximum strength at minimum weight
• Snell-FIA CMR 2016 certified — the highest safety standard for CMR-class karting, recognised by Kartsport NZ and Karting Australia
• FIA approved 3mm anti-fog visor — optically superior, fog-resistant, and FIA homologated for competition
• ST6 platform — Stilo's flagship racing helmet architecture, with advanced ventilation, premium padding, and precision fit engineering
• Natural Carbon finish — clean, purposeful, no graphics — the look of a helmet that means business
• 6 sizes (53–59cm) — precise fit across a wide head size range

Who Is This Helmet For?

• Kart racers who demand the best and won't compromise on quality or weight
• Junior and youth competitors in NZ and AU karting competition requiring Snell-FIA CMR 2016 certification
• Racers who want a clean, premium natural carbon finish — no graphics, no compromise
