In 2009, its first full season of World Superbike racing, Max Biaggi aboard the RSV4 reached the podium nine times, and won one race at the Brno Circuit. Aprilia factory teammate Shinya Nakano ended the season in 14th place. Biaggi won the championship in 2010, and was contracted to race the bike for another two seasons, citing his positive experience with the team and development of the bike into a successful racer and, despite his age, wanting to continue with the momentum they had built up. Max Biaggi ended his career winning the 2012 title with the RSV4. The Aprilia RSV4 is available as a customer-specified race bike from the factory as a Max Biaggi replica. Sylvain Guintoli won the 2014 Superbike World Championship season riding an RSV4 for the factory Aprilia racing team. Lorenzo Savadori won the 2015 FIM Superstock 1000 Cup season. A bike based on the RSV4 was used by Aspar Team and Paul Bird Motorsports, coming 11th and 12th in the 2012 and 2013 Grand Prix motorcycle racing seasons. ==References==
