Brief History of the Marque
Manufacturer: Nacional Motor SA, Martorellas, Barcelona
French rider Jacques Roca entered a modified Derbi under the Rabasa name in French road-racing events during the sixties and seventies.
In 1989 minimoto machines of this name appeared in various guises powered by Franco Morini engines and suitable for children 4 to 14 years of age.
Rabasa is the family name of the Derbi company, which was earlier known as Rabasa Derbi.
The Rabasa company is best known for its bicycles, and that part of the business was directed for decades by the daughter of the founder, Margarita Rabasa, along with Dante Adami. The history dates back to the 1920s when the Simeó Rabasa was a partner in the firm which eventually became Ducson. In the 1940s and 50s they were heavily involved in the production of Moto Guzzi Hispana .
Marketed as a separate brand, the SRS was powered by Iresa engines of 48cc and 53cc. It was a succesful model, but when Derbi took over from Rabasa the SRS production passed to Iresa and it vanished from the catalogue.
