In 1978, a "Martian" landed at the Motorcycle GP, an overseas rider who, thanks to his dirt-track and Goodyear tyre experience, rode his Yamaha 500 with a unique and personal style that made the motorcycle glide. His name was Kenny Roberts, and he won his first Grand Prix and those of the next consecutive two years. He drove a black and yellow motorcycle, is a Dainese rider and helped to create the first knee slider, which protects the knee as it continuously hits the ground. When you see yellow and black, you think of him. Here is the t-shirt that celebrates the umpteenth Dainese champion.
