Bell KC7-CMR Kart Helmet - Ayrton Senna / FREE HP Bag

Race in the Colors of a Legend

Ayrton Senna began his journey to three Formula 1® World Championships on a kart track — wearing a helmet in yellow, blue, and green. Those colors became one of the most iconic liveries in motorsport history. Now, the Bell KC7-CMR Ayrton Senna Special Edition lets you carry that legacy onto the track.

Produced under official license from Senna Brands and the Ayrton Senna Institute, this is not a generic tribute — it is an authentic, competition-ready kart helmet built on Bell's flagship KC7-CMR platform, wearing the exact color scheme Senna made famous.
