Giovanni Parrilla was a Spaniard who grew up in Italy. He was one of many new motorcycle manufacturers who sprung up after World War II. Part of his technical education came when he bought a Norton Manx and took it apart. The company's approach to styling was distinctive and they have joined other Italian small displacement bikes as favourites of the collector crowd.

Giovanni Parrilla built his first motorcycle in 1946, dropping his surname's second 'r' to call the machine 'Parilla'. Mr. Parrilla owned a shop on the outskirts of Milan specialising in the repair of diesel injector pumps. He also held an agency for Bosch sparking plugs.

The first Parilla motorcycle - a 250cc overhead-camshaft single-cylinder racer - was the work of Ing. Giuseppe Salmaggi, who already had the Gilera Saturno to his credit. Giovanni Parrilla was a big Norton fan so the 250 racer's engine employed a bevel-driven overhead-camshaft just like the British manufacturer's Manx. There the similarity ended however, for the Parilla was a thoroughly modern design boasting unitary construction of the engine/transmission and geared primary drive. The new power unit went into a welded loop-type chassis featuring a single down-tube, girder front fork and plunger rear suspension. (Later versions had a telescopic fork and swinging-arm suspension). Ridden on its debut by Nino Grieco on 1st October 1946, the Parilla could claim to be Italy's first new racing motorcycle since the War's end.

These were mainstays in Italian club racing as well as the town-to-town Moto Giro competitions. For safety reasons, these races on public roads were often limited to 175cc machinery and all interested Italian manufacturers produced bikes of this displacement.

It has the lean and hungry look of racing motorcycles of its era, lacking any compromises like a headlight, muffler of kick-starter. The clip-on handlebars and rear set pegs let the rider adopt the classic racing crouch in the days before riders hung off their bikes to secure higher cornering speeds. The black and red Dual seat tone paint is a residual seat of Parrilla's Norton Manx encounter. He often used the traditional black and red shades on different Parrilla models.

The here offered Parrilla 175cc MSDS with is overhead camshaft from the Amsterdam Italian Motor Museum, is a one of a kind with. This bike is a stunning example of an Italian racing bike from the time when Italian machinery ruled many road racing classes. Its lines are d

Daldi e Luigi Matteucci established a small company in 1919 in Milan named Società Anonima Daldi, which built automotive parts. In 1928, the company name changed to Officine Meccaniche Daldi and Matteucci and finally, in 1939, to DEMM, an acronym for Daldi and Matteucci Milan. The registered office remained in Milan, and a factory in Porretta Terme was erected which produced precision instruments and then, in 1952, building of mopeds and light motorcycles started.

In 1956, Demm established 24 world speed records in the 50cc class; this was followed by more competition success in the sixties, winning the Italian 50cc championship with their DOHC machine. While most of DEMM's proprietary engines and smaller models were two-strokes, it also built overhead-camshaft 4-strokes in capacities of up to 175cc. Demm two-stroke engines of 50, 53 and 75cc, and 4-stroke 125cc and 175cc bevel-driven OHC engines were sold to many motorcycle manufacturers. Engine production ended in 1983, but they continued selling motorcycle related products until 1988 when focus shifted entirely to gears for vehicles and machinery and were eventually absorbed by ZF.

NB: DEMM or Demm? The term DEMM is used to refer to the company itself, whereas Demm is most commonly used in Italy and elsewhere in Europe to refer to the brand, e.g., Demm Super Sport 1971.
