Triumph Bonneville
The Triumph Bonneville is a Types of motorcycles#Standard, standard motorcycle featuring a Straight-twin engine, parallel-twin four-stroke engine and manufactured in three generations over three separate production runs. The first two generations, by the defunct Triumph Engineering in Meriden, West Midlands, England, were 1959–1983 and 1985–1988. The third series, by Triumph Motorcycles Ltd, Triumph Motorcycles in Hinckley, Leicestershire, began in 2001 and continues to the present as a completely new design that strongly resembles the original series. The name Bonneville derives from the famous Bonneville Salt Flats, Utah, USA where Triumph and others attempted to break the Motorcycle land speed record, motorcycle speed records. Development history T120 Bonneville The original Triumph Bonneville was a 650 cc Straight-twin engine, parallel-twin motorcycle manufactured by Triumph Engineering and later by Norton Villiers Triumph between 1959 and 1974.

Triumph Bonneville T120
The Triumph Bonneville T120 is a motorcycle originally made by Triumph Engineering from 1959 to 1975. It was the first model of the Bonneville series, which was continued by Triumph Motorcycles Ltd. The T120 was discontinued in favour of the larger 750 cc T140 in the early 1970s. The Bonneville T120 name was revived in 2016 on a new machine with larger engine and updated specifications. One was used as a model for Sirius Black’s Motorbike in Harry Potter and the Sorcerer’s Stone. Development The Bonneville T120 was Edward Turner's last production design at Triumph (in retirement Turner designed the Triumph Bandit/BSA Fury which did not pass the prototype stage before BSA went under). The new motorcycle was conceived and developed so quickly that it was not included in the 1959 Triumph catalogue. With a parallel-twin (two-cylinder) engine the T120 was based on the Triumph Tiger T110 and was fitted with the Tiger's optional twin 1 3/16 in Amal ...

Les Harris (businessman)
Leslie Frederick Harris (1939 – 17 February 2009) was an English businessman and motorcycle enthusiast who resurrected the Triumph Bonneville for a few years in the 1980s. Born in 1939, he was described as the "saviour of the British motorcycle industry". Invited to Buckingham Palace and the Houses of Parliament, in 1987 he was visited by the Prime Minister Margaret Thatcher. He died in February 2009, aged 69. L F Harris International Ltd Harris began his own business in 1974 manufacturing and selling spare parts for classic motorcycles. As the leading British manufacturers such as Norton Motorcycles, BSA and Triumph went out of business, Harris bought as many spare parts as he could and set up L F Harris International Ltd at a warehouse in Newton Abbot. The venture was a success and he expanded by purchasing an engineering company in Leighton Buzzard and a retail shop in Paignton, Devon.

Devon
Devon ( , historically known as Devonshire , ) is a ceremonial and non-metropolitan county in South West England. The most populous settlement in Devon is the city of Plymouth, followed by Devon's county town, the city of Exeter. Devon is a coastal county with cliffs and sandy beaches. Home to the largest open space in southern England, Dartmoor (), the county is predominately rural and has a relatively low population density for an English county. The county is bordered by Somerset to the north east, Dorset to the east, and Cornwall to the west. The county is split into the non-metropolitan districts of East Devon, Mid Devon, North Devon, South Hams, Teignbridge, Torridge, West Devon, Exeter, and the unitary authority areas of Plymouth, and Torbay. Combined as a ceremonial county, Devon's area is and its population is about 1.2 million. Devon derives its name from Dumnonia (the shift from ''m'' to ''v'' is a typical Celtic consonant shift) ...

Disc Brake
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. The components include the disc, master cylinder, and caliper (which contains a cylinder and two brake pads) on both sides of the disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. Other designs were not practical or widely available in cars for anothe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Featherbed Frame
The featherbed frame was a motorcycle frame invented by the McCandless brothers and offered to the British Norton motorcycle company to improve the performance of their racing motorcycles in 1950. It was considered revolutionary at the time,"''As opposition companies strove to develop completely new machines with multi-cylinder engines, far more powerful than the Norton single, Bracebridge Street was content to find new speed in 1950 with a revolutionary new frame which steered and handled so superbly that it immediately earned the now forever-famous tag Featherbed''".

Triton Motorcycle
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. During the period in which Triton motorcycles were constructed, the Norton Featherbed frame was regarded as the best handling frame. Triton bikes aimed to combine the "best engine" with the "best frame" by replacing the standard Norton engine with a Triumph parallel-twin engine. Although "best" is subjective, a popular engine choice was the Triumph Bonneville unit with twin carburettors and twin camshafts. This pushrod engine gave good performance and reliability and could be more easily tuned for greater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribsa
The Tribsa, or Tri-B.S.A., was a custom built café racer or off road motorcycle of the 1960s and 1970s. Its name was an amalgamation of Triumph and BSA. The purpose was to combine the best elements of each marque to give a superior bike to either. A Tribsa involved a Triumph parallel twin engine installed in BSA motorcycle frame. Although both the BSA A65 and the Triumph 650 cc twins engines were overhead valve (OHV) units, only the Triumph had twin camshafts, which facilitated tuning for greater power output. The BSA frame was a duplex-cradle design which was considered stiffer and stronger than the Triumph's single downtube item. A batch of nine TriBSAs were planned by the factory (which factory?) for the 1966 ISDT using 348 cc, 490 cc and 'special capacity' 504 cc 'short' Triumph twin engines in a frame using geometry from the BSA Victor scrambler, Victor front forks and wheel together with a Triumph QD rear wheel in a Triumph swinging arm (''swinga ...

Café Racer
A coffeehouse, coffee shop, or café is an establishment that primarily serves coffee of various types, notably espresso, latte, and cappuccino. Some coffeehouses may serve cold drinks, such as iced coffee and iced tea, as well as other non-caffeinated beverages. In continental Europe, cafés serve alcoholic drinks. A coffeehouse may also serve food, such as light snacks, sandwiches, muffins, fruit, or pastries. Coffeehouses range from owner-operated small businesses to large multinational corporations. Some coffeehouse chains operate on a franchise business model, with numerous branches across various countries around the world. While ''café'' may refer to a coffeehouse, the term "café" generally refers to a diner, British café (colloquially called a "caff"), "greasy spoon" (a small and inexpensive restaurant), transport café, teahouse or tea room, or other casual eating and drinking place. A coffeehouse may share some of the same characteristics of a bar or restaurant, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unit Construction
: ''For the vehicle design where the vehicle's skin is used as a load-bearing element, see Monocoque.'' Unit construction is the design of larger motorcycles where the engine and gearbox components share a single casing. This sometimes includes the design of automobile engines and was often loosely applied to motorcycles with rather different internal layouts such as the flat twin BMW models. Prior to unit construction, the engine and gearbox had their own separate casings and were connected by a primary chain drive running in an oil bath chaincase. The new system used a similar chain drive and both had 3 separate oil reservoirs for engine, gearbox and primary drive. Triumph and BSA were already using cast alloy chaincases and started converting to unit construction in the 1950s. A driving factor behind the BSA/Triumph change was that Lucas had declared an intention to abandon production of motorcycle dynamos and magnetos, and instead produce only alternators. By contrast, V ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pre-unit Construction
Pre-unit construction, also called separate construction, is a motorcycle engine architecture where the engine and gearbox are separate components with their own oil reservoirs, linked by a driving chain within a primary chaincase. Mounting plates are usually attached to the frame allowing for chain adjustment by gearbox fore-and-aft movement and via screw adjusters and elongated mounting holes. Even though Singer offered an integrated engine and gearbox in a single casing in 1911, it was not until the 1950s that technical advances meant it was possible to reliably construct engines with integral gearboxes in a single unit, known as unit construction. Another variant is semi-unit construction, where the gearbox is bolted directly to the engine. Curiously, early BSA A10 and A7 parallel twins (650cc and 500 cc, respectively) were semi-unit construction, but the factory later adopted pre-unit construction. The term "pre-unit" was coined only after such engines were succeeded by "u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camshaft
A camshaft is a shaft that contains a row of pointed cams, in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers. Camshafts in piston engines are usually made from steel or cast iron, and the shape of the cams greatly affects the engine's characteristics. History Trip hammers are one of the early uses of a form of cam to convert rotating motion, e.g. from a waterwheel, into the reciprocating motion of a hammer used in forging or to pound grain. Evidence for these exists back to the Han Dynasty in China, and they were widespread by the medieval period. The camshaft was described in 1206 by engineer Al-Jazari. He employed it as part of his automata, water-raising machines, and water clocks such as the castle clock. Once the rotative version of the steam engine was developed in the late 18th century, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
