Jeff Harrington raced one of the most unique brands in AMA professional racing. Harrington, of Bakersfield, Calif., raced an Italian-made Vertemati SR570. Harrington had some solid results in the Unlimited Class during the 2003 AMA Supermoto season. While Vertemati was a rare brand in America, the team actually fielded a fair number of bikes in AMA Supermoto in 2003. Other riders who raced Vertemati that season included Leo Bagnis, Derrick Lucchesi and Jason Chisum.
