Part Two (1947-1976) of the definitive three-part history from producer David Wood about the World's most famous motorcycle races - the Isle of Man TT.

Nortons and Velocettes were initially the machines to beat. Freddie Frith, Harold Daniell and Artie Bell were the stars between 1947 and 1949 when the TT became part of the FIM World Championships.

The emergence of Geoff Duke signalled the dawn of a new era and in the late 1950s Bob McIntyre and John Surtees were showing a clean pair of heels. Surtees took the Senior 4 times until another great name appeared on the scene... Mike Hailwood.
