A Brief History of the Marque
The engineer Alberto Bulleri of Pisa built a horizontal two-stroke twin using cylinders from DKW, each having a displacement of 136cc giving a capacity of 272cc.
It had inclined finning, and the flywheel was enclosed in the crankcase in a separate chamber, with a 3 speed gearbox. It does not appear to have gone into production.
