The Sidewinders Speedway is a junior Motorcycle speedway that was opened in 1978 in the semi-industrial Adelaide suburb of Wingfield in South Australia. The Sidewinders U/16 Speedway Club Inc. was founded two years earlier in 1976 by Graham Baker and Roy Bitmead, with help from Rowley Park Speedway riders Robin and Kym Amundson, and their father Bill. As it was then, Sidewinders goal is to promote and develop speedway through its junior ranks with riders aged 4–15, something that had rarely been done in Australia to that point.
