The firm of CF (designers Catellia and Fiorani) had started building powerful little 173 cc and 248 cc face cam OHC singles in 1928.
They were very successful in racing. In 1937 the CF factory was taken over by the Fusi firm, which were the Italian FN importers. Next to the racing types with face cam engine, Fusi produced machines with J.A.P. engines that were built in Italy under licence. Fusi used gearboxes that were actually Burman designs produced under licence by FIAT. This beautifully restored piece of engineering has a four speed foot change gearbox and square engine dimensions of 68×68 mm. Two separate oil tanks are fitted, and the lubrication of the valve gear is effected through external oil pipes. Hairpin valve springs are employed, the cylinder has a forward slope of 15 degrees and the machine has rear springing with friction dampers. Power developed is given as 17 hp @ 7000 rpm, top speed is around 135 km/hour.
