Following Semior’s cessation in 1955, Edeta Industrias Mecánicas emerged, establishing its base at Avenida 26 de Enero, 8 Ripollet (Barcelona). Their inaugural offering was a 175cc motorcycle, very similar to the defunct Semior, with the most notable modification being the fitting of a chain transmission rather than the original shaft drive.
The 175cc model was fitted with the two stroke, air cooled, single cylinder engine that had been fitted in the Semior. The 175cc (62 mm x 57.8 mm = 174.502cc) engine claimed output of 8.5 HP @ 5,000 rpm and featured an aluminium cylinder head with a 4-speed gearbox. I don’t know of any survivors, nor have I seen a photograph of one.

In 1956, the company changed its name to Industrias Dami and decided to produce a new 125cc model. The 125cc (55 mm x 52 mm = 125.5cc) two-stroke, air cooled engine was believed to have been sourced from Rekord** and based on the unit fitted to the short-lived Pony brand. The engine claimed an output of 8.5 HP @ 5,000 rpm.
** The details of the engines used by Edeta are poorly recorded and still being researched.
The Edeta 125cc models transitioned to the proven and popular Hispano Villiers 10M engines. These engines remained in use until the production ceased in 1961. Throughout its seven-year tenure, Edeta’s spasmodic production tally scarcely reached a hundred units in total.
