Six times World Motorcycling Champion, six times TT winner, 1951 Sportsman of the Year - Geoff Duke O.B.E. was the name in motorcycling in the 1950s.
His extraordinary riding talent and almost scientific approach to racing established Duke as probably the first true professional to grace the pages of motorcycle sport history.
During the 1950s, he had such a following that 400,000 people - a record to this day for any GP - turned up to see him do battle for Norton with the mighty BMW team in Germany.
In this first and definitive biography Geoff Duke personally recounts the story of his remarkable career.
