The International Six Days Enduro is known as the 'Olympics of Motorcycling' such is the enormous amount of effort, stamina and skill required to compete. It is a 1000 mile test of mechanical and human endurance both off-road and on. Today's bikes are designed and built specifically for Enduro competition. Back in the Fifties, however, things were different. The event was known a's the International Six Days Trial and the bikes were based on standard road models with hardly and modification. Enduro Classics features grueling ISDT events with stars of the era competing in Italy, Austria and Wales during 1951, 1952 and 1954. They are linked by present-day reminiscences from gold medal winners of the past such as Jeff Smith and Eddie Dow. Two more gold medalists include Brian Martin and Norman Vanhouse, who were part of the BSA team who rode from Birmingham to Vienna and back to Oslo - a 4500 mile trip that won them the coveted Maudes trophy for achievements on two wheels. The team also competed in the ISDT en route and none of the riders dropped a single mark! The full flavor of their epic ride is featured here. These original films, together with the memories of the legendary riders, recapture an era when four-strokes dominated and an ISDT entry was a major adventure. Classic stuff, in more ways than one!
