Balkan was the first motorcycle built in Bulgaria. The first model, the Balkan M1, released in 1957, was built under the open license of DKW, and was identical to the DKW RT250. In 1960 the company started using a design similar to Jawa, and other contemporary motorcycles.

The "Balkan" is the first motorcycle built in Bulgaria. It is a product of the Number 12 factory and has a 250-c.c. engine in a pressed steel frame; not dissimilar to the popular Czechoslovakian Jawa. A 50-c.c. moped is -- since 1960 -- also among the "Balkan" products.
