Antonio Barbacil was technically gifted but he was hampered financially and, had to reach an agreement in 1957/58 with the suspension firm (Betor) for the manufacture of his last model. This agreement included the sale and transfer of all of his machinery and plans to Barcelona.
Under the terms of the agreement, Antonio Barbacil moved to Barcelona to become the Works Manager. Here, he directed the manufacture of this new motorcycle, which appeared on the market in 1959 under the brand name Dian GP in addition to the continued production of the renamed Barbacil 98cc (Dian Junior) and 123cc (Dian Sport) machines.
This low resolution photo of a 1960, Dian 125cc, was taken at the now closed Barcelona Motorcycle Museum. It is fitted with a Barbacil engine. The photo was downloaded from the 360carmuseum.com website, who I have contacted for permission to share here but the website seems to be defunct.
