MSA has affiliated clubs in metropolitan Adelaide, as well as country clubs as far widespread as Mt Gambier, Port Lincoln, Ceduna and Renmark. It continues to be the sole governing body of motorcycle sport in South Australia, and currently consists of 42 affiliated clubs.
Each club provides a Councillor to represent it at MSA general meetings. MSA through its Councillors elects a President, Vice President and two Board members at each alternate annual general meeting.
Under auspices of MSA, each sporting discipline is represented by a Sports Manager which, in turn, has its national counterpart in the form of MA Commissions. Representatives at state level are elected by the affiliated organisations. Each Sports Manager generally meets with a group of Consultants on a monthly basis to determine the direction of their discipline.
As the governing body of motorcycle sport in South Australia, MSA prepares annually a calendar of projected open sporting events for the forthcoming year. These events area allocated to the various clubs according to their applications and availability of dates. There are on average 120 calendared events conducted each year, and considerably more on an ad hoc basis.
