Maquinaria Y Elementos de Transporte SA (Mototrans) of Barcelona produced motorcycles and scooters between 1957 and 1983. It succumbed to financial problems and the factory was bought by Yamaha.
The factory built Ducati motorcycles which differed in detail to the Italian machines; for instance the use of Spanish-made Amal carburettors and some engine and gearbox internals. As well as a number of Ducati-engined singles they produced a parallel twin closely based on the Ducati SD500 Desmo. They also built the 1978 Yak 410 scrambler with their own engine (although at least one source says it was designed by Ducati), and a rather smart 50cc machine.
Yak 410 Specifications: 406 cc, 86 x 70, desmo valves, belt-driven
camshaft, 6 speed gearbox. Developed 38 hp at 8000 rpm. Around 80 of these were produced between 1985 and 1986. It appears to have the same engine as the Merlin DG11.
The 500 Nomada model had a Cagiva fourstroke engine.
There is a book on the marque in Spanish:

MotoTrans of Spain built many bikes under licence from Ducati. Some were identical to the Italian versions, other had differences, not only to the engine units, but they frequently used locally sourced cycle parts and electrics. England
