In 1925, the model range still included the SS80, along with the newly introduced SS100. That year, Brough Superior also produced a new lightweight model specifically for overseas markets, particularly Austria. This model was developed at the request of the Meyer Agency in Vienna. George Brough fitted a JAP 680cc side-valve engine into the old Mark I frame, and the bike appears to have been assembled using surplus parts. It wasn't made available in the home market until 1926, and even then, only in limited numbers.
In 1926, Brough Superior announced two new models based on the SS100. The first was the Alpine Grand Sports model, inspired by the success George and 'Gentleman' Dickson achieved in the 1925 Austrian Alpine Trials. The second model was known as the SS80-100.
During this time, Brough Superior was closely associated with T.E. Lawrence, better known as Lawrence of Arabia. Lawrence, who was a personal friend of the company's founder, George Brough, owned seven Brough Superior motorcycles, starting with his first purchase in 1922. Tragically, Lawrence's fatal motorcycle accident in 1935 involved a Brough Superior.
Overall, the years 1925 and 1926 were significant for Brough Superior, as the company innovated, expanded its product line, and ventured into overseas markets.
