Bell KC7-CMR Ultra Helmet (CMR)
The Bell KC7-CMR Ultra belongs to the Bell Ultra Series range and is built specifically for young karting competitors. Its shell is constructed entirely from carbon fibre, leaving the woven structure exposed across the full surface of the shell - the material is finished with a gloss lacquer that highlights the characteristic carbon weave pattern without additional graphics or colour inserts. The overall form draws on the aerodynamic profile of the HP7 model, translating into a smooth, sculpted shape with carefully considered airflow lines.
An oval Bell Helmets sticker with a white background and red logo is positioned on the forehead. Matching brand markings appear on both sides of the visor locking mechanism and on the visor itself. The model designation KC7 Ultra is visible on the right side of the chin section. The visor adjustment mechanism has an anthracite-tone finish that contrasts subtly with the mirror-polished hinge surfaces. The interior is lined with soft black padding; a red strap accent is visible at the chin buckle when the helmet is open.
The ventilation system uses 14 openings to channel airflow through the shell - intake ports are positioned at the front and top of the shell, exhaust ports at the rear. The visor is a DSAF unit from the SE07 series, 2 mm thick, providing resistance to deformation and a clear, undistorted field of view. The aerodynamic shell geometry, derived from the HP7, reduces air resistance during competitive driving.
The Bell KC7-CMR Ultra carries the Snell-FIA CMR-2016 homologation, the certification required by regulations for competitors under the age of 15 in competitive karting. It is suitable for both boys and girls and meets federation requirements for age categories up to 15 years. As part of the Ultra Series, it represents Bell's top-tier offering within the brand's karting helmet range. A considered choice for young licence-holders equipping for a race season under CMR regulations.
