4H Moto Classic Barcelona-Catalunya is a classic motorcycle endurance competition held at the Circuit de Barcelona-Catalunya in Montmeló, Spain. Promoted by Fly Actions in collaboration with the Circuit, it is part of the 24H Moto Barcelona-Catalunya Martimotos weekend and is designed to give historic racing motorcycles a prominent place in modern endurance sport. The inaugural event is scheduled for 10 and 11 July 2026, using the circuit’s full 4,657-metre FIM Grand Prix layout.

The race covers four hours, split into two two-hour sessions so teams compete in both night-time and daytime conditions. Teams comprise two or three riders per motorcycle, with mandatory pit stops. The programme also includes free practice, including night sessions, and qualifying. Up to 40 teams can enter across five classes based on motorcycle age, engine type and capacity: Classic, Superbike 1000, Superbike 750, Supersport 600 and Open. The event shares a paddock and weekend programme with the 24-hour race, offering participants and spectators a dedicated celebration of classic motorcycles and endurance racing.
