The Norton Motorcycle Company is a brand of motorcycles, originally based in Birmingham, England. This company is owned by Indian multinational giant TVS Motor Company. For some years around 1990, the rights to use the name on motorcycles was owned by North American financiers. From 2008 to 2020, a line of motorcycles was produced under owner and chief executive Stuart Garner. Due to financial failure with large debts, in April 2020 administrators BDO agreed to sell certain aspects of Garner's business to Project 303 Bidco Limited, a new business established for the purpose with links to Indian motorcycle producer TVS Motor Company.
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 and its legendary and still-unbeaten 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, eventually closing in February 1971.
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block.
A motorcycle engine is an engine that powers a motorcycle. Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used.
The Triumph Trident and BSA Rocket 3 was a technically advanced, high-performance roadster motorcycle made by Triumph Engineering and BSA from 1968 to 1975, and sold under both the Triumph and BSA marques. Alongside the Honda CB750, and later the Kawasaki triples, it brought a new level of sophistication to street motorcycles, marking the beginning of the superbike era. The Honda CB750 overshadowed the Trident to be remembered as the 'first superbike', in spite of the Triumph Trident actually debuting before the Honda by a few weeks.
Triton motorcycles were hybrid motor cycles built from the 1950s to the 1970s that involved fitting Triumph engines into Norton frames. Because no factory offered Triton motorcycles, they were typically privately constructed. However, some UK dealers offered complete bikes. The aim was to combine the best elements of each marque and thus gain a bike superior to either. The name 'Triton' is a contraction of Triumph and Norton; 'Triton' was the name of a mythological Greek God.
The 1964 Ducati Berliner 1260 Apollo was a prototype 1,257 cc (76.7 cu in) V4 engine motorcycle producing 100 bhp (75 kW) and capable of over 120 mph (190 km/h). It was never put into production, but did influence other production Ducatis that followed. Both Ducati and their United States distributor, Berliner Motor Corporation, were experiencing declining sales of existing small-capacity single-cylinder models, and sought to create a bike to compete with Harley-Davidson. Berliner Motor was keen to have a model that could win lucrative police motorcycle supply contracts, and that could also sell as a civilian touring bike.
The Harley-Davidson Twin Cam are motorcycle engines made by Harley-Davidson from 1998 to 2017. Although these engines differed significantly from the Evolution engine, which in turn was derived from the series of single camshaft, overhead valve motors that were first released in 1936, they share a number of characteristics with nearly all previous Harley-Davidson engines. Both engines have two cylinders in a V-twin configuration at 45°, are air-cooled, and activate valves with push-rods. The crankshafts have a single pin with a knife and fork arrangement for the connecting rods. These are sandwiched between a pair of flywheels.
Norton-Villiers was a British motorcycle manufacturer formed in the 1960s following the collapse of AMC. With the general decline of the British motorcycle industry, under a British Government initiative it was later combined with the remnants of BSA Triumph to form Norton-Villiers-Triumph.
The Norton Commando is a British Norton-Villiers motorcycle with an OHV pre-unit parallel-twin engine, produced by the Norton Motorcycle company from 1967 until 1977. Initially having a nominal 750 cc displacement, actually 745 cc (45.5 cu in), in 1973 it became an 850 cc, actually 828 cc (50.5 cu in). It had a hemi-type head, similar to all OHV Norton engines since the early 1920s.
The Velocette Venom was a 499 cc single-cylinder four-stroke British motorcycle made by Velocette at Hall Green in Birmingham. A total of 5,721 machines were produced between 1955 and 1970.
The Triumph Bonneville 790 cc is a British motorcycle that was designed and built in Hinckley, Leicestershire by Triumph Motorcycles Ltd between 2001 and 2007, when the engine size was increased to 865 cc.
The Velocette Viper is a British motorcycle made by Velocette between 1955 and 1968. Built using traditional methods and materials, it struggled to compete against more modern machines, so from 1960 the designers added new glass fibre enclosure panels, making the Viper one of the first enclosed production motorcycles.
The BSA C15 was a 250 cc single-cylinder ohv motorcycle manufactured by the British company BSA from September 1958 until 1967, and was BSA's first four-stroke unit-construction bike. For most of that period, after the introduction of 'Learner Laws' in 1961, a 250 cc was the largest capacity solo machine that a learner could ride unaccompanied when displaying L-plates in the United Kingdom. A road-going Sports derivative was added in 1961, and off-road versions, for Trials and Scrambles, were also available in the range.
The isolastic frame, designated by Norton as GlideRide, used a system of engine-to-frame mountings incorporating rubber bushes to isolate the vibration of the vertical twin engine from the frame and rider. The isolastic frame was developed for use with the Commando inclined engine, whilst the Featherbed frame continued in production for the Mercury with a softer-specification 650 cc vertical-engine until 1970.
The Yamaha XJ650 Maxim is a mid-size motorcycle by the Yamaha Motor Company introduced in 1980 as the Maxim I and produced through 1983. Yamaha designed the high-performance XJ650 as a brand-new four-cylinder with shaft drive, and built it specifically as a special cruiser. The XJ Maxim was the successor of the XS Special introduced in 1978.
George Brown (1912-1979) was born in Nottingham, England. Known primarily as a motorcycle racer, he has been called " the father of British sprinting". Brown raced a variety of bikes but is most closely associated with the Vincent brand. For a time he worked at Vincent, where he headed up their Experimental department and raced the factory-backed single and V-twin bikes. Brown left Vincent to establish his own motorcycle shop and as a sideline built high-performance sprint bikes that he rode to several national and international records.
The Norton Commando Production Racer was a hand built production racer produced by Norton-Villiers from 1970 - 1972. It was based on the road-going Norton Commando, and although fitted with lights it was never intended as a road bike. The model was commonly known as the Yellow Peril.
The Norton Manxman was a 650 cc vertical twin motorcycle manufactured by the British Norton Motorcycle Company at their Bracebridge St, Birmingham factory for export. It was first shown at the November 1960 Earls Court Motorcycle Show and listed by the American importer, Berliner, in their catalogue from 1961 to 1963. Berliner had asked for the model to be named Manxman although the twin had never been raced at the Isle of Man.
The Norton 650 Dominator was a 650 cc vertical twin motorcycle manufactured by the British Norton Motorcycle Company from 1962 to 1967. Initially production was at Norton's Bracebridge St, Birmingham factory, but following the factory's closure in 1963, production was transferred to parent company AMC's works in Plumstead, London. Initially produced in single and twin carburettor versions, the single carb version were soon discontinued. The twin carb version, the 650SS, was described as the 'Best of the Dominators'.
