The pre-WWII four cylinder Gilera racer, based on the Rondine

Romeo 1969-75 Italy
Maker of 50cc Minarelli-engined ultralightweights. Odd examples of the motorcycle and moped like machines find their way out of Italy.

Rondine (Dates as detailed) Italy
Four concerns are briefly mentioned here as one led to the post WWII world championship winning Gilera fours. Each concern appears to have been independent of influence of other makers of same name. Some have intimated links between the Rondine marques, all included here to distance them from each other.

1923-28: Maker of 98cc Train engined two-stroke lightweights.

1934-35: Famous engineers Carlo Gianini and Pietro Remor designed and developed their transverse ohc four-cylinder OPRA racing motorcycles c1927-29. It’s claimed Carlo Guzzi and Oreste Pasolini took a long look at this design before working on their own transverse four of 1931-32 (engine on display in Moto Guzzi museum).

Produced by the Campagnia Nazionale Aeronautica (Rome) with financial backing from Count Bonmartini the Rondine developed by OPRA designers Gianini and Remor was an ohc water-cooled transverse four. Raced by Amilcare Rosetti and Piero Taruffi, the Rondine was bought by Gilera who further developed the concept, often racing it under the Rondine logo.

They continued briefly in this vein after WWII, further developing the design once they’d begun to recover from the war leading to the famous Gilera fours raced so well by Masetti, Duke, Liberati, McIntyre et al. It’s claimed MV took a long look at the Rondine design before developing their own transverse fours employing selected engineers who’d experience of Rondine/Gilera models.

1951-54: Two-stroke German Sachs engine lightweights designed by Martino Siccmario.

1968-c1972: Tiny 50cc racers and off-road motocross style motorcycles by former MV Agusta employee Alfredo Copeta.

Rond-Sachs 1971-75 Holland
Two-stroke Sachs-engined lightweight motocross motorcycles that enjoyed some national success and outings at Continental meets.

Rosselli 1899-c1910 Italy
Famous founding pioneer of the Italian motorcycle industry. Emanuel di A Rosselli began with tiny engines clipped to bicycles then developed a small range of models with usually up to 300cc engines fitted to purpose made motorcycle frames. Some sources claim Rosselli produced cars but evidence seems scant.

Roussey and PP Roussey 1931-56 France
Brothers Paul and Pierre Roussey established their motorcycle business at Meudon. Assembly began with a range of 100 to 500cc motorcycles with proprietary engines. After WWII the brothers restarted production with two-stroke lightweight motorcycles and a neat 48cc cycle clip-on with the engine mounted outboard of the cycle’s left rear fork leg. As well as loose clip-ons the Roussey brothers built complete cyclemotor machines including stylish tandems with dropped rear frame.

In 1952 Paul and Pierre unveiled a stylish sleek scooter, looking some claim like an imaginary period two-wheeled Citroen. Offered with either 125 or 175cc water-cooled engines it was updated in both mechanical and styling aspects in 1953 and 1955. The brothers often used proprietary engines including Staub, Chaise and Aubier-Dunne.

Rover 1902-25 (1885 to date) UKApruil 1910 and three riders pose with their Rover motorcycles
JK Starley unveiled his concept safety cycle in 1885, naming it the Rover, with true volume production beginning in 1888. Following experiments motorising a bath chair with a De Dion engine, Rover began motorcycle production in 1902 followed two years later by car manufacture, with a neat 8hp job designed by Edmund Lewis. Although still listed for the 1926 season, it’s believed manufacture of the last 350cc unit construction Rover motorcycles ended in 1925.

And while the Rover car brand now seems gone forever – unless it’s to rise in China or elsewhere – the name Rover continues in the Land Rover built vehicles launched for 1948 and continuing in rather more sophisticated forms today.

Under Starley’s guidance, the fledgling Rover cycle concern was established at The Meteor Works, West Orchard, Coventry. After Mr Starley’s death in 1901, Harry Smith took over as managing director, and following board meetings the company began to develop two and three-wheel motorised prototypes including clip-on engines on cycles and a tiller steering three-wheeled forecar.

However, real motorcycle manufacture didn’t start until late 1903, following a glowing appraisal of their first ‘proper’ motorcycle, which comprised a side-valve four-stroke engine with mechanically operated valves housed in a purpose designed motorcycle frame.

Although the Rover was an outstanding machine for its day, the company board was less than happy building top class motorcycles, which they were forced to market alongside those from rival makers they considered less than worthy.

Single speed Rover motorcycle, dating from 1911After an impressive – for the period – production run of 1250 machines, Rover ended motorcycle manufacture in 1905. By 1908 the company was under the control of JK Starley’s son – confusingly also named JK Starley – and the company modestly returned to motorcycle production with Motosacoche clip-ons fitted to their sturdy cycles.

During 1910 mutterings emanated from the Rover works implying updated 500cc motorcycle development was under way. However, this was shelved in favour of an all new 499cc side-valve model designed by John Greenwood, which took just six weeks from drawing board to its launch at the 1910 Olympia Show. Although boasting no staggering major cutting edge designs, it was a quality made 500 with a distinctive oil pump blister on the side of the tank. With updates this engine remained in production until 1923.

Initially pedal start direct drive models were on offer but soon options of hub gears/clutches (Armstrong) became available, while some owners opted for proprietary clutched or variable gear pulleys. Rover motorcycles performed well at hill climbs, trials and also gained a number of places at Brooklands. Their TT results were less impressive, although they gained the manufacturer’s award in 1913. With justification, Rover included a direct drive run-and-jump TT model in their pre-WWI range.

Over 4500 motorcycles had been built by the outbreak of WWI during which Rover supplied an initial order of 350 models to Russian allies, with a further 3103 machines supplied to the Allied Forces before the war’s end. Despite the war, British makers were allowed to build motorcycles for the civilian market – in most cases – until 1916 and Rover modernised their range for the 1915 season. Gone was the pedalling gear and in came three speed counter shaft gearboxes with kick-starter made by another major motorcycle maker for Rover. A 5-6hp V-twin with JAP side-valve engine was also unveiled, replacing an earlier briefly built MAG engined model.

1919 TT Model Rover motorcycle still retained direct driveReturning to peacetime, the Coventry maker continued with more of the same – 499cc singles or JAP engined V-twins with counter shaft gearboxes. Even the direct drive TT model was still on offer. To an extent it was an old fashioned range, but the undoubted build quality shone through.

Rover dallied with ohv design for the 1921 IoM Senior TT but proving tests at Brooklands weren’t impressive. Under the New Rover Cycle Co Ltd banner, three side-valve singles with novel Brampton chain (chain incorporating coil springs which acted as transmission shock absorbers) entered, two started and one finished with Walter Brandish junior 13th. It was Rover’s last racing foray in the Island.

Although Rover had steadily adopted all chain drive for some models since the war, belt drive wasn’t finally dropped for all versions until 1922. But for the rest it seemed a case of yet more of the same, although there were rumours of top secret, cutting edge development work at Coventry.

Launched at the 1922 Olympia Show for the 1923 season was an all new unit construction three-speed ohv 250cc (63 x 80mm) single with ML Maglita for ignition and electric lights. Unfortunately, it wasn’t quite ready and early production models suffered problems with engine expansion and too flimsy front forks. Quick modifications made it a much better machine but perhaps its reputation was already harmed. That reputation was further dented by a less-than-average performance in the 1923 ACU Six Days Trail, with two retirements and only Rover stalwart Dudley Noble securing a Gold.JAP-engined v-twin Rover model replaced the earlier MAG-engined v-twin

For the 1924 season all models except the unit 250 were dropped, the only new addition a 350cc unit model. The 350cc model was a similar machine to the 250 but with an enlarged bore (74 x 80mm). The 350 was good for 60mph with the standard iron piston and more with optional higher compression silicone alloy piston. The last Rover motorcycles were built in 1925 and any remaining stocks were cleared by the factory during 1926 – how long the last few hung around in dealer’s shops is unclear. Destined to become quality car makers, Rover never built motorcycles again.

Oozing quality in a gentlemanly old fashioned way, Rover singles make a superb veteran or early vintage mounts while the V-twins are equally attractive.

Rovena c1961-68 Spain
Marketing brand for two-stroke lightweights built by leading Spanish maker Sanglas. Models included 250/325cc Hispano Villiers engined touring and sporting two-stroke twins and 50-100cc Zundapp engined ultra lightweights. By 1968, sales of civilian and police Sanglas models had grown to such an extent they ended Rovena manufacture.

Rovin 1920-34 France
Well thought out 100-175cc two-stroke lightweights, many featuring suspension damping on girder front fork, built by Raoul Pegulu de Rovin at his Billancourt workshop. Also built a small number of touring and sporting machines using up to 500cc JAP engines. Rovin lightweights, often with outside flywheel and forward facing carburettor, featured well in French reliability type trials of the period.

A clever engineer and able racing car driver, M Rovin bought the San-Sou-Pap (without any valves) motorcycle factory at Colombes in 1929. Rovin built tiny 260cc single cylinder plus 425cc and later 462cc flat-twin engined cars. In the cyclecar style many were neat, nippy, sporting little jobs. His postWWII model were popular in Paris during the 1950s.
