Originally titled the International Six Days Trial, in 1981 the FIM decided to update the name to International Six Days Enduro, the name Enduro having been devised by the Americans and popularised by many motorcycle manufacturers also greater reflected the change in the event from a trial to more akin to a rally featuring skills more associated with cross country motocross.
Over its long history the rules and conditions have changed to keep in step with the developments in the sport, but it remains a supreme test of rider and machine.
Over the six days and upwards of 1250 miles a rider must contend with strict rules about time allowances and restrictions on mechanical replacements, carrying out his or her own motorcycle repairs.
For 2013, the 100th anniversary of the holding of the first ISDT, the FIM announced that there were a record number of pre-entry requests of 820 covering 35 nations from across the Globe with 600 entries being allowed to compete.
The medals are typically awarded based on percentage of finishers, or relative to the best individual performance in the event within their specific class.
However, on 2 November of that year, the FIM International Disciplinary Court (CDI) rejected the appeals lodged by the Fédération Française de Motocyclisme (FFM), the Real Federación de Motociclimo (RFME) and the Auto-Cycle Union (ACU) therefore, the decision made by the ISDE committee to disqualify the eight riders for missing a routine check was upheld[3] meaning three of the French World Trophy team were disqualified resulting in team being reclassified to 23rd with Australia officially awarded as winner of the 2015 World Trophy title.
