1. John Surtees
John Surtees is the first man to manage winning world championships in both bike and car races and will probably go down in history as the only one. During his bike racing career, Surtees won the world title four times in the late 1950s. He then switched over to Formula One and won the 1964 world championship in a Ferrari. He remains one of the biggest legends on either two or four wheels.
