Reports indicate that Romboni was struck by another rider after suffering a crash in the second practice session of the Sic Supermoto Day, before being immediately evacuated by helicopter to intensive care. 

Despite the best efforts of the staff at the Santa Maria Goretti hospital, Romboni succumbed to his injuries later in the afternoon. A six-time Grand Prix winner in the 1990s across the 125 and 250 classes, Romboni was one of the many stars taking part in this weekend's Sic Supermoto Day event held at the Latina circuit in memory of the late Marco Simoncelli.
