Bell RS7-K Stamina Karting Helmet - K2025 / FIA8878
The Bell RS7-K Stamina is a dedicated karting helmet engineered from the ground up for drivers who put real laps on their gear. Built on the proven HP7 platform with a lightweight carbon fiberglass composite shell, it carries Snell K2025 homologation and delivers race-ready aerodynamic and ventilation performance straight out of the box. The optical-grade Double Screen Anti-Fog visor and 14-channel ventilation system keep your head cool and your vision clear through every session — rain or shine. This is a helmet built for the karter who takes their equipment as seriously as their lap times.

Bell has been building serious race helmets for decades, and the RS7-K Stamina is the brand's answer to a question every karter eventually asks: what does a true competition-grade karting helmet look like when it's built specifically for the demands of the sport — not adapted from a car racing platform?
The answer starts with the shell. The RS7-K Stamina uses the same carbon fiberglass composite architecture found on Bell's HP7 design, tuned with aerodynamic shell geometry and a shield interface that works together to reduce internal noise, improve stability at speed, and enhance energy management in an impact. Inside, an advanced multi-density, multi-piece EPS liner replaces the single-layer foam found in lower-tier lids — because not all impacts hit the same spot at the same angle, and your liner shouldn't treat them like they do.
Ventilation is a genuine strong suit here. Fourteen air intake and extraction channels move air aggressively through the helmet, and the system is designed to work even in the relatively low-speed airflow environment of a kart — not just when you're doing 150 mph. The optical-grade injected 3mm Double Screen Anti-Fog visor handles visibility in variable conditions, and a synthetic rubber gasket seal keeps water out of the eye opening when it starts raining mid-session.
One important note for drivers upgrading from car racing: the RS7-K is a dedicated karting helmet and is not compatible with FHR anchor systems or devices — by design, since kart racing doesn't use them. The non-fireproof interior lining is purpose-built for extra durability, optimized for the demands of high-frequency karting use rather than fire exposure.
Available in Anthracite/Orange and Anthracite/Yellow, sizes 57-58 through 61-61+. Bell SmartLock visor mechanism included.
