In 2006 the Grand National Championship was split into two separate series: Grand National Championship Singles (for short track and TT events) and Grand National Championship Twins (for half mile and mile events); no overall title was awarded, although in 2007 there was a de facto champion by virtualization of winning both championships. Single-cylinder engines were limited to 450cc.
Since 2010 the Grand National Champion title was reinstated and awarded to the rider who scores the most combined points. New manufacturers began to enter and find success in the sport. In 2010, Ducati earned its first GNC win. On August 24, 2013, three different OEMs finished on the podium for the first time since 1972. One week later, Harley-Davidson failed to make the podium for the first time since 1987.
