The RS7-K Ultra helmet upgrades the RS7-K helmet with a
full carbon fiber construction making this helmet the lightest weight adult karting helmet Bell offers. This helmet includes Bells 4-piece air intake system for maximum airflow and is updated to the latest
Snell K2025 karting standard.
The RS7-K Ultra Carbon helmet is the pinnacle of karting helmet technology- weighing in well under 3lbs in all sizes! Less weight on your neck lap after lap makes it an easy choice for karters looking for an edge, while the HP7-derived profile signals its Formula 1 heritage at a glance. For karters who want the lightest, most advanced helmet in Bell's lineup, the RS7-K Ultra is the answer.
The RS7-K Ultra features a front aero fascia, an ultra-lightweight carbon fiber shell, and a pro-style interior with neck padding for outstanding comfort. The direct flow chin bar vents on the front of the helmet help to increase airflow and prevent shield fogging.
The sleek, aerodynamic design features an advanced ventilation system with
14 intake and extraction channels that can be used with or without air intake scoops.
On this Ultra version, the 4-piece air intake scoops come pre-installed from the factory. The RS7-K's uses the DSAF shield (double screen anti-fog) and a rubber gasket seal prevents water from entering the helmet in rain conditions.
New for this version of the RS7-K Ultra is the addition
Bell's SmartLock visor system. This mechanism ensures the shield is locked firmly in place during any collision while also allowing easy opening and closing via a depressible tab. This development improves safety and is being implemented across Bell's pro level helmet lineup.
The Bell RS7-K Ultra Helmet has a range of karting specific features- the helmet's chin guard face piece is removable and the integrated channels offer multiple options to install radio microphone systems. It also is available with optional aero accessories including spoilers & gurneys to prevent helmet lift at higher speeds.
The RS7-K Ultra is certified to the Snell K2025 standard which requires the helmet to be tested to the Snell SA2025 impact test criteria, but does not require the helmet to be fire retardant. This allows the interior to be of a
more durable material allowing this helmet to easily handle years of racing.
