Bultaco was a very successful Spanish motorcycle manufacturer in the '60s. After splitting with Montessa, Francisco Bulto went on to manufacture motorcycles. Affectionately known as Senor Bulto, Francisco had a strong love of competition on all fronts. His road racers were legends in Europe. The Metralla shares many of these attributes. They were fitted with probably the sexiest drum brakes around. A 250 Metralla could wear out a Triumph twice its size on a back road. It is only missing a taillight, which is a generic Lucas item. They later even pushed the envelope with water-cooled road racers (banned in the U.S.).
