The National Association of Speedway Racing is deeply saddened by the news that South Australian identity, entrepreneur and racing car driver Kym Bonython passed away Saturday after a lengthy illness.

Among his other iconic achievements, such as assisting to secure the Formula 1 Grand Prix for South Australia, Bonython managed Adelaide's Rowley Park Speedway for more than two decades and was the patron of Wendy Turner's Speedway City.

He was also among the inaugural 10 members inducted into the Speedway Hall Of Fame in 2007.
