Ultra-Lightweight Premium Carbon Composite Shell

The Bell RS7-K Ultra features a Premium Carbon Composite shell designed to combine lightweight construction with exceptional structural performance. Its advanced shell construction helps minimize unnecessary helmet weight, supporting driver comfort during demanding kart racing sessions.

Derived from the HP7 platform, the helmet's shell geometry and shield profile are engineered to improve aerodynamic efficiency, reduce internal noise, and enhance energy management.

Advanced Multi-Density Impact Protection

Inside the RS7-K Ultra, Bell uses an advanced multi-density, multi-piece energy-absorbing liner engineered to provide effective impact protection. This sophisticated liner construction works with the carbon composite shell to manage impact energy while maintaining the fit and comfort required for competitive karting.

14-Channel Ventilation System

Managing heat inside a karting helmet is essential during long practice sessions, qualifying, and race conditions. The RS7-K Ultra features 14 air intake and extraction channels positioned throughout the top and chin bar to promote airflow.

The installed two-part center and side intake system helps direct fresh air into the helmet while strategically positioned extraction channels allow warm air to escape.

SE07 3mm Double Screen Anti-Fog Shield

The Bell RS7-K Ultra comes equipped with an optical-grade injected SE07 3mm Double Screen Anti-Fog (DSAF) shield. Its dual-screen construction helps reduce condensation and maintain clear vision during humid, cool, or rapidly changing racing conditions.

The shield is paired with Bell's SV (SE07) pivot system and SmartLock mechanism for smooth operation and secure closure.

A synthetic rubber eyeport gasket creates a seal around the visor opening to help limit water and dirt intrusion during wet or dusty track conditions.

Bell SmartLock Shield Mechanism

Bell's SmartLock mechanism provides a secure shield closure system designed for racing applications. Combined with the SE07 3mm visor and compatible pivot hardware, the system delivers reliable operation throughout demanding karting sessions.

Snell K2025 Karting Certification

The Bell RS7-K Ultra is certified to the Snell K2025 karting helmet standard. This certification is intended for kart racing applications and may be accepted by racing organizations that recognize Snell K2025 helmets.

Important: The RS7-K Ultra is a dedicated karting helmet and is not compatible with Frontal Head Restraint (FHR) anchor systems or devices. Drivers participating in automobile racing should select a helmet that meets the certification and restraint requirements of their racing organization.
