The Bultaco Matador was the factory’s enduro motorcycle for most of the 1960s and 1970s. Built from 1963 to 1979, it grew out of the Sherpa S that had won gold medals at the 1962 International Six Days Trial and became one of the most respected off-road bikes of its time.

History of the Bultaco Matador

Bultaco’s interest in what was then called “Todo Terreno” began in 1962, after Oriol Puig Bultó and José Sánchez won gold medals at the International Six Days Trial at Garmisch-Partenkirchen. They rode almost standard Sherpa S 175 machines without any assistance and became the first Catalans to take a gold medal there. Oriol Puig Bultó, nephew of the owner Francesc Xavier Bultó, went on to compete in ten Six Days events and win nine medals, five of them gold, and he was the main force behind the factory’s participation and the development of the future Matador.

Starting from the 1962 Sherpa S, the company built a prototype called Matador with the engine enlarged to 200 cc and developed it in competition, including the ISDT. A short series of that first Matador was sold almost exclusively in the United States until the American distributors asked for changes and for the engine to be enlarged to 250 cc. The model then went into series production in 1965 as the Matador Mk2 USA and became a sales success, especially in America. In 1967 came the Mk3, an update with a simple, uncomplicated concept: raised intake and exhaust, a taller trials-style handlebar and good ground clearance, while the five-speed gearbox combined short lower gears for steep climbs with longer top gears for fast tracks. A kit called ISDT was offered for riders who wanted to compete seriously.

For the 1970 Six Days at El Escorial in Spain, Bultaco presented the Mk4, with a completely renewed engine and a stronger gearbox, new brakes and a larger, more comfortable seat. The following year came the SD, short for Six Days, a replica of the works bikes for the most committed privateers: a fuel tank with the filler on the left to leave room for a tool bag with a transparent pocket for the route map, a longer and bulkier exhaust, and a modified rear frame to carry it. The SD engine produced 28 CV at 7,000 rpm against 23 CV at 6,200 rpm for the original Mk4, close to the 30 CV at 8,000 rpm of the works prototypes. From 1975 the Mk9 moved to a 350 cc engine, and the Matador remained in production until 1979. Riders such as José Sánchez, Oriol Puig Bultó, Casimir Verdaguer and Narcís Casas won several Spanish championships on it.

Design and features
