Manufactured by Motocycletas Evycsa, 19 and 20 in Plaça Tetuan, Barcelona, 1953-1957 (1)
Established by Màrius Vilaseca, a former motorcycle racer, the firm built motorcycles using Fita-AMC 169cc OHV four-stroke engines and possibly also 250cc.
Vilaseca died in a motorcycle accident in 1955 while training for the Costa Brava Rally.
Evycsa was taken over by Fita in 1958, and the motorcycles were then marketed under the name MAF.
N.B. 1. Another source gives dates of 1954~1959
