A Brief History of the Marque
Designed by Küchen and built at a garment manufacturer in Esses in 1953-54, the Opti 247cc OHC twin-cylinder engine by Küchen developed 14 hp at 6,500 rpm.
It reportedly suffered from several problems including cooling, camshaft drive chain, and conrod lubrication problems. Some of these faults did not become apparent until the engine had been run for around 10,000 km, and appears that the Opti factory, with no automotive background, lacked the necessary development engineers for the project.
The Opti engines were used by Rabeneick, Tornax and UT. All suffered financially as a result, Tornax in particular. For them, it was the death knell. Motosacoche also built an Opti twin model.
