Bugatti Circuit is the permanent race track within the wider Le Mans complex and has been in use since 1965. Unlike the full Circuit des 24 Heures, which combines permanent sections with public roads, the Bugatti layout is a purpose-built circuit used throughout the year for motorcycles, cars, club events and professional competition. The current layout measures 4.185 km and runs clockwise. Over the decades it has undergone several configuration changes, with the modern version in use since 2002 after a series of revisions during the 1980s and 1990s. The circuit is especially well known for major motorcycle events such as the French MotoGP and the 24 Heures Motos, but it also hosts car racing, track days and test activity. The venue benefits from the broader Le Mans infrastructure, including pit buildings, dedicated paddock access, medical facilities and large spectator capacity. A major resurfacing project was carried out in 2016–2017 to renew the top asphalt layer after more than a decade of heavy use, with motorcycle performance and grip consistency being a key reason for the work.
