Toni Finsterbusch began riding motorcycles at the age of seven. In 2010 he was runner up in the International German Championship, and in 2011 Finsterbusch rode as a wildcard rider at the Sachsenring round, where he finished 12th. In the 2012 season Finsterbusch teamed up with Cresto Guide MZ Racing as it sought to make its mark on the new 4-stoke Moto3 category. Though the team unfortunately folded due to lack of funds, meaning that for 2013 Finsterbusch has another shot with new team Kiefer Racing on its Kalex KTM machine.
