Opti Motorcycle Engines

A Brief History of the Marque

The Opti 250cc OHC twin-cylinder engine reportedly suffered from serious lubrication problems, a fault which did not become apparent until the engine had been run for around 10.000 km.

These 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.
