Built in 1974 by Bernard Droulhoile who worked with the French Yamaha importer Sonauto, the Moto Moraco was based on the TZ250/350 using a monocoque* frame and an enlarged engine. It was campaigned by Christian Bourgeois and Patrick Pons in the 500cc GP. Pons scored a 4th place at Spa, the team's best result. The machine entered only four events.
The chassis weighed a mere 7.35 kg, giving the machine a dry weight of 103kg. It developed 64 h.p. at 10,000rpm.
N.B. Droulhiole used the term the term 'polycoque' in his patent.
