In 1989 and 1990 the Championship went back to a World Cup status, as the number of events required by the FIM Sporting Code was not reached.

In 2015 FIM and the pan-European television sports network, Eurosport signed a deal for the promotion and coverage of the competition.

With this, the organization re-ordered the events, in order to the new championship starting in September and finishing in July, with the European races being held during the winter avoiding the MotoGP and Superbikes schedules.

The overall appearance of the bike cannot deviate from the homologated model, but the fork, damper, swing-arm, brakes, radiator and exhaust can be modified.

The engine is as provided by the manufacturer, with very limited modifications permitted (injector jets and fuel mapping, clutch reinforcement, a different exhaust silencer, etc.).

In both Formula EWC and Superstock, the fuel tank is modified to a maximum capacity of 24 litres and fitted with a quick refuelling device.

The category includes motorcycles whose engine, main frame or suspension are completely different from the design of the original models.

Machines in the Experimental category appear in the general classification of the event but are not classified in the World Endurance Championship.
