#2 John Surtees
Surrey-born John Surtees' flair for motorbikes and racing were inherited from his father - who owned a motorcycle shop. His father Jack Surtees was also a competitive motorcycle racer.
His name holds a special place for the iconic brand MV Agusta as he was the first champion from the team. He was so much loved in Italy during those days primarily for his resounding success with MV Agusta that he was nicknamed 'iglio del vento' ( meaning son of the wind).
Starting from 1956, Surtees went on a Cup-winning spree winning the 500cc Championship in 1956, 1958, 1959 and 1960. He would also triumph in the 350cc class in 1958, 1959 and 1960.
In 1960, he retired from Motorcycle racing and remarkably made the switch to Formula 1. Remarkably in 1964, while as a member of Team Scuderia Ferrari, he won the Formula 1 World Championship.
To this date, he is the only individual to have won both the MotoGP Premier Class title (called the 500cc Motorcycle Grand Prix Racing Championship at the time) and the Formula 1 Driver's Championship.
