Ayrton SennaBrazilian yellow helmet · 1990 season design

The story

Sid Mosca's design: a yellow background with a green stripe around the upper visor and a light metallic blue stripe around the lower visor, the three colours of the Brazilian flag; Mosca said the stripes stood for movement and aggression and the yellow for youth. In 1990 and 1991 Senna wore Honda's own Rheos helmets, and the design changed only with sponsorship.
