What Are These Helmets Suitable For?
Understanding what type of karting helmet you need starts with knowing the type of events you’re entering and the regulations that apply. Each of the new Stilo ST6 models in this blog meets specific homologation standards, making them suitable for different age groups, competition levels, and governing body requirements.
Stilo ST6 CMR Zero Carbon Kart Helmet
The Stilo ST6 CMR Zero Carbon is the most advanced youth karting helmet in the Stilo range, developed specifically for drivers under the age of 15 competing at the highest levels of karting. What sets this model apart is its incredibly lightweight design, thanks to the use of premium-grade carbon fibre. This makes a real difference over a full race weekend, reducing fatigue and helping young drivers stay sharp and focused on track.
Every part of the helmet is engineered with performance in mind. The carbon shell is not only featherweight but also incredibly strong, meeting the latest FIA 8874-2019 CMR standard. This certification ensures that the helmet meets strict safety requirements while still allowing a compact and lightweight design, which is crucial for younger racers.
Inside, the helmet is fitted with a plush, supportive liner that holds the head securely in place without creating pressure points. The streamlined outer shell improves aerodynamics and stability at speed, while the front chin vent and top air vents manage airflow to help keep drivers cool even during intense sessions.
This is the kind of helmet serious young competitors wear when they want the very best in comfort, protection, and weight-saving technology.
Key Features:
- Ultra-lightweight carbon fibre shell for minimum weight and maximum strength
- FIA 8874-2019 CMR approval, designed specifically for kart drivers under 15 years old
- Compact shell size for a better fit and improved comfort for younger head shapes
- Optimised internal padding designed to stay secure during high movement while keeping pressure low
- Enhanced airflow system including chin and top vents to improve cooling and ventilation
- Aerodynamic profile for reduced drag and improved helmet stability
- Wide eyeport for maximum visibility on the kart circuit
This is one of the best youth karting helmets available on the market today, designed for young drivers who take their racing seriously and want the same kind of helmet technology trusted by professionals.
Stilo ST6 CMR Lite Carbon Kart Helmet
The Stilo ST6 CMR Lite Carbon is the perfect balance between high performance and lightweight construction, making it a strong choice for competitive youth kart racers. It shares the same FIA 8874-2019 CMR homologation as the Zero Carbon model, meaning it’s designed for drivers under 15 years old and meets the latest safety standards. However, the Lite Carbon version uses a slightly different carbon composite structure that brings the price down while still offering significant weight savings over standard composite helmets.
What makes the Lite Carbon model stand out is its ability to offer high-end features without going all the way to the ultra-premium price of the Zero Carbon. It retains the aerodynamic design and advanced venting system found across the ST6 range, with top and chin vents that manage airflow effectively during intense karting sessions. The helmet also features a wide eyeport for enhanced visibility and a plush, secure-fitting liner designed to provide comfort over long stints.
The shell is compact and race-oriented, designed to fit smaller head shapes comfortably while reducing the strain on the neck and shoulders over time. For younger drivers looking to compete seriously without going for the top-tier helmet, the ST6 CMR Lite Carbon is the ideal middle ground.
Key Features:
- Lightweight carbon composite shell offers excellent strength-to-weight ratio
- FIA 8874-2019 CMR approval, making it suitable for kart racers under 15 years old
- Wide visor aperture provides excellent lateral visibility on track
- Internal padding designed for comfort and helmet stability under movement
- Streamlined aerodynamic shape for improved helmet balance at high speeds
- Effective ventilation system with chin and top vents to manage heat build-up
- Lower price point than the Zero Carbon while still delivering strong performance and premium feel
This helmet is a smart upgrade for young kart drivers looking to move into lightweight carbon equipment without jumping to the absolute top of the range. It delivers most of the performance of the Zero Carbon in a more accessible package.
Stilo ST6 KRT Carbon Kart Helmet
The Stilo ST6 KRT Carbon is designed for adult kart drivers who want to combine carbon fibre performance with a practical, race-ready design. Unlike the CMR helmets which are built for younger drivers under 15, the KRT Carbon is homologated to Snell K2020 standards, making it fully suitable for all senior karting classes and events where full Snell approval is required.
What sets the KRT Carbon model apart is its high-grade carbon fibre shell, which provides excellent strength and weight reduction while still offering the durability required for intense adult kart racing. The carbon weave finish gives it a premium motorsport look, and its shell design follows the same aerodynamic profile used across the ST6 range, offering reduced drag and improved stability at speed.
Ventilation is well thought-out, with air intake ports at the chin and crown for consistent airflow across the head and face. Inside, the helmet features a carefully contoured lining that offers a snug fit without excess pressure points, helping to minimise distractions while driving. The helmet is also compatible with Stilo’s range of visors and accessories, allowing drivers to tailor it to different lighting or weather conditions.
This model is especially popular with club-level and competitive karters who want a professional-grade carbon helmet without stepping into bespoke or CMR-only designs. It’s a strong option for those wanting to move beyond entry-level without compromising on comfort or safety.
Key Features:
- Snell K2020 approved, suitable for senior karting and competitive events
- High-quality carbon fibre shell with a race-inspired finish for reduced weight and improved stiffness
- Streamlined ST6 shell shape for better aerodynamics and balance on high-speed circuits
- Multiple venting points at chin and crown to control temperature and airflow inside the helmet
- Wide visor opening for clear peripheral vision and on-track awareness
- Premium fitment interior with removable padding for a tailored feel
- Accessory compatible, supporting a range of Stilo visors, spoilers, and spares
Overall, the ST6 KRT Carbon delivers serious race-ready performance in a lightweight, carbon-finished design, making it a trusted helmet choice for committed adult kart racers.

Stilo ST6 KRT Composite Kart Helmet
The Stilo ST6 KRT Composite Kart Helmet offers a cost-effective entry into the ST6 adult helmet range while still delivering the performance and safety features that kart racers expect from Stilo. Built with a lightweight composite shell rather than full carbon fibre, this helmet is ideal for drivers who want high-quality materials and race-focused design without stretching to the price of a carbon model.
Despite being the most accessible of the four new ST6 options, the KRT Composite helmet still meets the Snell K2020 homologation, which means it is fully approved for senior karting classes across competitive events in the UK and beyond. The composite shell construction provides a great balance between strength and weight, offering dependable protection and reduced driver fatigue during long stints behind the wheel.
The interior is finished with the same ergonomic shaping and padding seen in the rest of the ST6 line-up, giving a snug and secure fit that helps with focus and feedback on the track. It also shares the same wide visor aperture for enhanced vision, and includes efficient ventilation with frontal and crown vents to help keep temperatures under control.
This helmet is particularly popular with club racers, track day karters, and newer adult competitors looking to upgrade from an entry-level helmet into something race-ready, reliable, and purpose-built without breaking the bank.
