The company “Industrias Reyac-Ocáriz” was founded by Jaime Ocariz in Tolosa, in the Pays Basque. From 1947, Talleres Ocaritz produced an auxiliary engine that was designed to be used on a standard bicycle frame and these engines were branded as Ziraco (his surname inverted). They also provided the Ziraco engines for other mopeds like the Miner, built in Donostia.
They went on to manufacture a moped, the Lanch, with engine capacity options of 74cc and 98cc. They were described as quite old fashioned, but they had gained a reputation for reliability. The 98cc version proved not to sell particularly well, faced with a lot of competition at this capacity, most notably from Derbi and Lube, both of whom produced more modern and better performing examples at that capacity.
This Lanch 74 is in the Team Lazpiur Collection at Bergara, Gipuzkoa.
An additional complication came in 1958 when Spain introduced revised regulations that made it necessary to obtain a licence and insurance for bikes over 75cc. Smaller capacity bikes could still be ridden as a moped but, in 1962, the capacity regulations were revised down again, this time to be less than 50cc.
The company also produced moped engines of 49cc and 63cc under license from SER Etablissements Seronge of Levallois-Perret in France. (See separate SER Chapter)
Production finished in 1962 or 1965, depending on the reference source.
