Biaggi, a former world champion in the 250cc category, went on to finish runner-up in both the 500c and MotoGp categories before turning his talents to the world Superbike series. The Italian posted a message on his Twitter account earlier Wednesday which read: “Today is going to be a new day for me... things will never be the same.”
He later told reporters: “I have officially retired.”
Biaggi (41) competed in motorcycling’s most illustrious category, GP, for the last time in 2005 when he finished fifth in the series for his then team Honda. His career best finish in GP was a second place behind unstoppable compatriot Valentino Rossi, in 2002.
After 2005 Biaggi lost his ride to that year’s 250cc world champion Dani Pedrosa. The Italian walked away from MotoGP to focus his attention on the Superbike series, finishing third in his maiden season with Suzuki in 2007 before winning the championship for the first time with Aprilia in 2010. Biaggi topped the Superbike standings for a second time at Magny-Cours in France last month where he claimed the title.
