70 years ago, a disciplined force of Nazi NSKK paramilitary stormtroopers and regular Wehrmacht soldiers invaded the Isle of Man to seek victory in the world’s toughest motorcycle races.

Full-scale war against Germany was only three months away and the Third Reich’s Führer Adolf Hitler was determined to teach Britain a sharp lesson in Aryan supremacy before the guns began to fire in earnest.

In The Nazi TT, veteran motorcycling journalist Roger Willis has blended a unique cocktail of politics, history and balls-out bike racing. His book explains how Hitler’s henchmen turned German motorcycle sport into a paramilitarised adjunct to the Nazi Party’s evil ideology during the 1930s and tested their might on the TT Mountain Course.

It reveals who the racers and their Nazi puppet-masters on the Island in 1939 actually were, what they achieved and what happened to them afterwards. You just couldn’t make this stuff up.
