Geoff Duke was a multiple world championship motorbike rider who achieved his success in the 1950s. Here, he takes us for a lap of the Nürburgring on four wheels ahead of the 1955 German Motorcycle Grand Prix, which he duly won.

Forget the most obvious changes, such as the lack of armco, just look at how dodgy the tarmac is in places!
