Manufactured by Breitfeld & Danek, Prague 1927-1929
Designed by the famed JF Koch the BD unit-construction DOHC 498cc single quickly became a very popular mount.
BD also built sidecars and sidecar combinations. In 1928 they supplied the police force with 30 such outfits, and 40 solos went to the military.
The firm was purchased by Praga and the BD became the Praga BD - and a legend was born.
