This 1956 GILERA 175cc Super Sport is an authentic factory bike and was very advanced for its time. There are only two GILERA 175cc Super Sport registrated in the Netherlands.

Throughout the early 1950s, it was Gilera's racers that grabbed the headlines, taking six individual World Championships and five manufacturers' titles. Although racing generated valuable publicity, it was sales of road bikes that paid the bills. The majority of machines sold were lightweights based on the overhead-valve 125 single that had first appeared in prototype form in 1948.

Developed and enlarged first to 150cc and then 175cc, these simple OHV singles were top sellers throughout the 1950s and into the 1960s, although their high price outside Italy made them a relatively rare sight abroad.

BM Bonvicini & Moto BM appear to be the same Italian marque. There were two other brands with the name BM, see BM (France) and BM (Turin). The founder of BM Bonvicini was Mario Bonvicini (born Granarolo dell'Emilia 1903 - died Bologna 1986), who was a professional and successful motorcycle racer between 1926 and 1930. In 1926, Bonvicini won the Astico-Brenta and the Tre Valli Varesine. In the following season he participated in the Giro d'Italia, finishing second in the first stage, and was tenth in the Giro del Veneto.

After WO-II, in 1950, he started with the production of light motorcycles with German JLO two-stroke built-in engines, as well as some of his own design. 4-stroke models were also introduced in the years 1952/1953. The BM Bonvicini Lusso had a 100cc NSU Fox engine and there were also 125 and 250cc models, the last of which even had an overhead camshaft. Some of the factory output was marketed in Germany under the Tornax banner.

In 1956, the range was considerably expanded with a 50cc model, a 75cc scooter, a 150cc 4-stroke with four gears and a 75cc triporteur. In the following years, 50cc, 75cc, 83cc and 125cc models were sold, included 50cc and 175cc racing machines with frames by Verlicchi. Also a moped. The ‘Jaguarino Turismo’ and the ‘Jaguarino Cross’, both produced by BM Bonvicini, with two stroke engines of 48cc. Minarelli engines were fitted to the Pokerino scooter of 1963.

In the 1970’s BM Bonvicini built various sports mopeds, scooters and minibikes, this time using Morini Franco or Minarelli 2-stroke motors, some with 6-speeds! Moto BM was a past master at choosing fantasy model names like Pokerino, Minotauro and Jaguarino! One of the firm's promotions offered just the two words, 'Ultra Bologna.' The range of models quickly declined in the 1980s. In 1988, the Company closed their doors.

One of the most famous names in Italian motorcycling history, the Meccanica Verghera concern can trace its history back to 1945 when the first two-wheeled machine to bear the MV moniker appeared. MV Agusta started with the production of the 98, this was a modest scooter designed to meet the need for cheap transportation, with the MV Company looking to diversify away from its principal base in the aeronautical industry.

MV quickly expanded the model range to include more sporting machines and established a reputation for building winning race bikes. MV officially began racing in 1946 but it was the new 4-stroke 125cc single and 500cc four-cylinder machines of 1950 that put the brand on the map, the latter giving Les Graham and John Surtees world titles. Meanwhile the range of road bikes continued to expand through the 1960s, with MV one of the few Italian manufacturers rising to meet the challenge of the Japanese through diversification.

The 4-stroke 175, launched with little fanfare in 1957, was a conventional but attractively styled machine available in Turismo, Sport and Lusso models and remained in production until 1960. Sold in both pushrod and more expensive single-cam versions, the former offering mechanical simplicity and reliability, the latter a more sporting edge. Both used an open duplex cradle frame with swing-arm rear suspension and a teledraulic fork, along with a unit construction four-speed gearbox.

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

The machine presented here a very rare 1956 Gilera 250cc from an Italian Motor Museum, with aluminum cylinder was specially built for the Giro D’Italia Milano, by engineering students from the University of Milan. Only 5 or 6 of these machines built by these students exist worldwide. It comes with his official lead seal of the “Giro d’Italia” and his official racing number “52”. This Gilera 250cc Street Racer is in generally excellent condition and after the usual safety checks ready for setting forth on the street again and joining the next year “Giro d’Italia”.

The motorcycle manufacturer was founded in 1909 by Giuseppe Gilera in Arcore. In 1935, Gilera acquired rights to the Rondine four-cylinder engine. It was the world's most powerful engine with 45 kW (60 hp) at that time. The first across-the-frame 4-cylinder motorcycle was the racer 1939 Gilera 500 Rondine. It had double-over-head camshafts, forced-inducting supercharger and was water-cooled, producing 60 kW (80 hp) at 9000 and had a top speed of 140 mph (230 km/h). This formed the basis for Gilera racing machines for nearly forty years. From the mid-thirties, Gilera developed a range of 4-stroke engine machines. The engines ranged from 100 to 500 cc.

After withdrawing from competition in 1957, Gilera changed direction abruptly. They downplayed their hitherto successful line of 4-stroke singles and began to focus on motocross and off-road events in association with independent specialist Elmeca. Sales declined through the 1960s and by 1968, the company was in receivership. The company was purchased by Piaggio in 1969.

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.

This 1956 MV AGUSTA 175 ‘CSS-5V Regolarità Monoalbero’, here offered is arguably a very rare motorcycle. MV AGUSTA produced the 175 ‘CSS-5V Regolarità Monoalbero’ between 1954 and 1956.

Initially fitted with the 175 ‘CSS’ engine, they replaced it in 1955 with the model ‘175 CSS-5V’. The frame is the series “CSS” with a modified closed cradle, telescopic front fork and raised exhaust system. MV AGUSTA produced these ‘175 CSS-5V Regolarità Monoalbero’ exclusively for the official MV Regolarità team. It definitely belongs to the most attractive MV machines ever built.

Between 1954 and 1956, MV AGUSTA achieved 17 wins in total with the ‘175 CSS-5V Regolarità Monoalbero’. MV pilot M. Fornasari won a Gold Medal on his ‘175 CSS-5V’ during the International Six Days Trial (ISDT), and in general, the MV Agusta Team collected 7 victories.

The MV AGUSTA 175 ‘CSS-5V Regolarità Monoalbero’ were never available on the open market. Between 1954 and 1956, only SIX (..!!!) machines were built, exclusively for the MV Regolarità (‘Regolaristi’) team. As far as we know, only two have survived. The finest one is this one, which is in a beautiful condition and almost original. That makes this MV AGUSTA 175 ‘CSS-5V Regolarità Monoalbero’ a real treasure, a true gem that is missing in any serious MV Agusta collection around the world.

Only in exceptional cases, a copy was occasionally sold between private collectors in the past and as far we know, this is the first time an MV AGUSTA 175 "CSS-5V Regolarità Monoalbero" will be sold . A unique opportunity to become the owner of one of the rarest and most unreachable Enduro machines.

This very rare 250 ‘Four In Line’ Racing Rumi is a jewel of Italian craftsmanship and Motorcycle performance. The ‘Four In Line’ Racing Rumi 250 is one of only three in existence and was constructed by Giuseppe Fabbri in 1960. Giuseppe Fabbri was a former Gilera agent in Lugo di Ravenna, Italy.

The ‘Four In Line’ Racing Rumi 250 consists two 125 Moto Rumi two-stroke twin engines with horizontal cylinders. Giuseppe Fabbri constructed only 10 ‘Fabbri’ engines: two 3-cylinder horizontal; three 4-cylinder horizontal (including the here presented Racing Rumi 250 of The Amsterdam Italian Motor Museum); two x 4-cylinder V-shape; one 6-cylinder horizontal; one 8-cylinder V-shape. The sound of these machines was surely breathtaking!

The Moto Rumi company was founded in 1914 by Donnino Rumi. ‘Officine Fonderie Rumi’ as they called the company at that time, supplied cast components to the textile machinery industry. At the outbreak of World War II, Rumi became involved in the manufacture of armaments, miniature submarines and torpedoes. The anchor in the Moto Rumi logo reminds us of this period. After the war, Rumi undertook general engineering work and like many Italian companies, chose motorcycles as its next target.

By 1949, the firm unveiled an exquisitely designed laid-down two-stroke twin-cylinder motor of 125cc with a 180-degree crankshaft and shapely unit-construction crankcase. The original Rumis used cast-iron cylinder barrels, and their chassis featured plunger rear suspension with undamped telescopic forks up front, full-width aluminum brake hubs and the motor slung under the frame tubes and held at two points. In 1950, Rumi decided to get involved in the manufacture of lightweight motorcycles. It was also decided to base the powerplant on the horizontal twin two-stroke unit of 125cc capacity. Rumi started manufacturing the Squirrel or Scoiottolo - a pressed steel monocoque body with tubular swinging arm rear suspension and tele forks with 14-inch wheels and three gears.

From 1952, Rumi built a SuperSport version of its twin for road racing with two carburetors, which was superseded by the Gobbetto racer and the Junior Corsa that had a full swingarm frame and serious tuning for its 175cc engine, which was good for 100 mph.

The company participated in a wide range of competitions immediately, including the ISDT (where it won the Team Prize in 1954 with three golds), long-distance races (winning the&
