Velocette Valiant
The Velocette Valiant was a British motorcycle produced by Velocette from 1957 to 1963. Launched at the 1956 Earl's Court Motorcycle Show, the Valiant had a 192 cc (11.7cu in) flat-twin engine but was expensive and criticized for its underpowered engine. Development In the mid-1950s Velocette had two very different lines of motorcycles. Alongside the larger and more conventional M series, they produced a series of enclosed small capacity four-stroke flat twins for the commuter market, when most of their competitors were producing two-stroke singles. Launched at the Earls Court Show in November 1956 the ''Velocette Valiant'' was a development of the Velocette LE. It had a two piece cover that enclosed most of the crankcase and gearbox. The engine was based on the LE engine but differed from it considerably, with the engine converted to air cooling for simplicity and lightness. Revised cylinder heads with overhead valves were used, with the compression ratio increased t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velocette Valiant 1959
Velocette is a line of motorcycles made by Veloce Ltd, in Hall Green, Birmingham, England. One of several motorcycle manufacturers in Birmingham, Velocette was a small, family-owned firm, selling almost as many hand-built motorcycles during its lifetime, as the mass-produced machines of the giant BSA and Norton concerns. Renowned for the quality of its products, the company was "always in the picture" in international motorcycle racing, from the mid-1920s through the 1950s, culminating in two World Championship titles (1949–1950 350 cc) and its legendary and still-unbeaten (for single-cylinder, 500 cc machines) 24 hours at over 100 mph (161 km/h) record. Veloce, while small, was a great technical innovator and many of its patented designs are commonplace on motorcycles today, including the positive-stop foot shift and swinging arm rear suspension with hydraulic dampers. The business suffered a gradual commercial decline during the late 1960s, eventual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Overhead Valve
An overhead valve (OHV) engine, sometimes called a ''pushrod engine'', is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first succ ...

Flat-twin Engine
A flat-twin engine is a two-cylinder internal combustion engine with the cylinders on opposite sides of the crankshaft. The most common type of flat-twin engine is the boxer-twin engine, where both pistons move inwards and outwards at the same time. The flat-twin design was patented by Karl Benz in 1896 and the first production flat-twin engine was used in the ''Lanchester 8 hp Phaeton'' car released in 1900. The flat-twin engine was used in several other cars since, however a more common usage is in motorcycles; early models oriented the cylinders in line with the frame, however later models switched to the cylinders being perpendicular to the frame to provide even cooling across both cylinders. Flat-twin engines were also used in several aircraft up until the 1930s and in various stationary applications from the 1930s to the 1960s. The Australian lawnmower manufacturer Victa also produced a flat-twin engine push mower from August 1975 to 1980 dubbed as the ‘Twin 500’ and â ...

Velocette LE
The Velocette LE is a motorcycle made by Veloce Ltd from 1948 to 1971. The designation LE stood for "little engine". Used by over fifty British Police forces, the police riders became known as "Noddies" because they were required to nod to senior officers, and the LE was nicknamed "the Noddy Bike". Production ended in 1970 when the company ran into financial problems and went into voluntary liquidation. The Mk I LE Velocette's Director, Eugene Goodman, planned an innovative and radical design that would appeal to a new market that needed cheap, clean and reliable transport. Designers Charles Udall and Phil Irving developed the Velocette LE as a "conceived-as-a-whole" design, with engine, gearbox, drive shaft and bevel box in a single unit to do a specific job. The Velocette LE was launched at the British International Motor Show at Earls Court in 1948 as the "Motorcycle for Everyman". With a 149 cc four-stroke, side-valve, water-cooled, horizontally opposed twin-cyli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorcycle
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earls Court Exhibition Centre
Earls Court Exhibition Centre was a major international exhibition and events venue just west of central London. At its peak it is said to have generated a £2 billion turnover for the economy. It replaced exhibition and entertainment grounds, originally opened in 1887, with an art moderne structure built between 1935 and 1937 by specialist American architect C. Howard Crane. With the active support of London mayor Boris Johnson, in an attempt to create Europe's "largest regeneration scheme", its proposed heritage listing was refused after it was acquired by developers, who promptly in 2008 applied for and were granted a Certificate of Immunity from Listing by English Heritage, and its demolition was completed in 2017. Located in Earl's Court but straddling the boundary between the Royal Borough of Kensington and Chelsea and the Borough of Hammersmith and Fulham, it was the largest such venue within the capital served by two London Underground stations—one of them, Earl's ...

Fibre Glass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoffmann Gouverneur
Hoffmann was a bicycle manufacturer in Ratingen-Lintorf, Germany. Between 1948 and 1954 the company also manufactured motorcycles. It made a range of models using engines from 125cc to 250cc made by ILO, and the Gouverneur, which had a transversely-mounted 248 cc flat twin four-stroke engine designed by Richard Küchen, and shaft drive. The Gouverneur was developed into the MP 250-2 and finally, in 1953, the S 300 model. From 1949 to 1954 Hoffmann also made at least 60,000 Vespa motor scooters under license. A licensing dispute brought this to an end in 1954. At the same time, Hoffmann also withdrew from making its own motorcycles, and had further legal problems with their microcar, the Auto-Kabine. Beginning Jakob Oswald Hoffmann moved his Solinger Bicycle Factory to Lintorf, near Düsseldorf, shortly after the end of World War II. In the immediate postwar era, the factory made household goods, tools, and bicycles. The factory began making motorcycles in 1948. Vespa prod ...

Victoria (motorcycle)
Victoria was a bicycle manufacturer in Nürnberg, Germany that made motorcycles from about 1901 until 1966. It should not be confused with a lesser-known, unrelated Victoria Motorcycle Company in Glasgow, Scotland that made motorcycles between 1902 and 1928. In its early decades Victoria in Nürnberg fitted proprietary engines purchased from various manufacturers including Fafnir, FN, Minerva and Zédel. 1920–1932 In 1920 Victoria launched the model KR 1, which has a 494 cc BMW twin-cylinder side-valve flat twin (boxer engine) mounted longitudinally in the motorcycle frame. The engine produced and transmission was via a two-speed gearbox. When BMW started making its own motorcycles, Victoria turned to making its own engines. In 1923 Victoria launched its KR 2, an overhead valve (OHV) flat twin producing . In 1924 Victoria followed this with the KR 3, which produces and has a 3-speed gearbox. In 1925 Victoria built Germany's first forced induction engine, and in 1926 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
