Ducati Road 250
The Ducati Road 250 is a  single cylinder bevel drive SOHC motorcycle produced by the Spanish manufacturer MotoTrans, who were licensed by Ducati to produce motorcycles under the Ducati brand name and was produced from 1972 to 1977. The model was intended to be a Spanish domestic market version of the 250 Scrambler, although it was also exported to the US in 1972/3. History
In post-Civil War Spain, the Franco regime banned the import of motorcycles and also forbade foreign nationals from settling in Spain, or stating a business there. MotoTrans was set up to manufacture Ducati motorcycles under licence in Barcelona in 1957. The Road was introduced in 1972 as a Spanish version of the 250 Scrambler. However, the model used the longer stroke 'narrow case' engine of the 24 Horas rather than the 'wide case' engine of the Scrambler. A locally built Amal carburettor and Spanish Telesco front forks were fitted. The bike was finished in Black with a metallic burnt orange tank and mudguards and chrome headlight. The American Ducati importers, Berliner Motor Corporation, were in dispute with the Italian factory over pricing from 1971 to '73 and chose to import from MotoTrans instead during this period. Amongst the models imported in '72 - '73 was the Road 250. Road 250 77
An updated version, the Road 250 77, was introduced in 1977. Electrics were uprated to 12 volts and stainless steel mudguards were fitted. The instrument panel from the 500 twins were also fitted. Technical details
