The Sery (from Serenella, one of Cesare's daughters) appeared in 1955-56 was top of the range. It was a single cylinder OHV four-stroke and 80° inclined valves, with a hemispherical combustion chamber. The cylinder was cast iron with integral barrel and it had a one-piece crankshaft.
The clutch was mounted directly on the left end of the crankshaft. A primary transmission with straight-toothed gears delivered power to the three-speed gearbox. Engine lubrication was splash system, without oil pump. The two versions (Turismo and Sport) had power output of 2 and 2.4 hp respectively. Top speed was 60 km/h at 5,500 rpm.
The tubular frame had an unusual structure, very close to a double raised cradle. The famous engineer Cesare Bossaglia worked on their design, before moving to Parilla.
Well over 50% of the mopeds built by Nassetti went to Belgium and Holland.
