While I am on a motorcycle bent I asked Trove when the first 'official' Motorcycle Club was established in the area? This clipping seems to be the first reported move towards a club. 1925. The equivalent today would be the ACT Motorcycle Club, or Canberra Rider's I suppose... Although my personal favourite is the Canberra based Fat Bastards.
