In the 1990s, Class C was introduced to Australia, with its main growth being over  the past few years, as the Indian’s joined the ranks. The rules adopted by Australia,  replicate the AHRMA rules from the USA. This allows global competition when the  opportunities present themselves. 

Class C racing is the only vintage, pre-war class that is capacity limited. Machines racing in the series are mostly stock which keeps the cost down, competition close and enjoyment to the maximum. For Australia, deviation has been allowed from the AHRMA rules, to include the more readily available 741 Military Scout.
