Southern Downs Road Race Series Classes

Each year the Motorcycle Sportsmen hold Club Championship known as the Southern Downs Road Race Series. This is a well contested series providing classes for all types of machines and riders.
Events on the Motorcycle Sportsmen of Queensland’s racing calendar include race classes to cater for most types of motorcycles and sidecars in the club’s racing calendar. Typically, multiple classes are grouped into Formulas which make up the individual grids at club racing events. Motorcycle Sportsmen of Queensland are a Motorcycling Australia (MA) affiliated club and all club events are conducted under MA permits. As described below, many of the rules associated with the race classes provided by the club are as per the MA Manual of Motorcycle Sport (MoMS) which is available from the MOMS website. There are some classes which are not included in the MoMS but are supported by the club. For these classes, links to (brief) rules have been included below.
