Velocette Thruxton
The Velocette Thruxton was a sporting motorcycle produced by Velocette between 1965 and 1971. Revealed at the 1964 Earls Court Show, it was the final development of Velocette's antiquated pushrod single, the Venom. Sometimes referred to as the ''Venom Thruxton'' or simply ''Thruxton'', some surviving examples could be 'upgraded' replicas based on the Venom or Viper, as many parts in the range were interchangeable. Due to the high values involved and possibility of fakes, a register was established by a member of the Velocette Owners Club, using production data of engine and frame numbers acquired after the factory closure, to enable owners and potential buyers to confirm provenance when selling and buying. The Thruxton ceased production only when the company folded in 1971. Development An optional cylinder head for the Venom became available for racers in 1964; a Venom equipped with this revised cylinder head took first in its class at that year's ''Thruxton 500'', a enduranc ...

Velocette
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, eventua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Close-ratio Transmission
A close-ratio transmission describes a motor vehicle transmission with a smaller than average difference between the gear ratios. They are most often used on sports cars in order to keep the engine in the power band. There is no industry standard as to what constitutes a close-ratio transmission, a transmission that one manufacturer terms close-ratio may not necessarily be considered close-ratioed by another manufacturer. Generally speaking, the more gears a transmission has, the closer they are together. A continuously variable transmission has a near infinite "number" of gear ratios, which implies an infinitely close-ratio between gears. However, with no specific gear ratios, it would not be considered a close-ratioed transmission. Comparison with ordinary transmission This table compares the ratios of three Porsche 911 vehicles from 1967 to 1971, the first being the standard 901/75 transmission, the second being the 901/76 transmission denoted "For hill climbs", and the third ...

Nose Cone
A nose cone is the conically shaped forwardmost section of a rocket, guided missile or aircraft, designed to modulate oncoming airflow behaviors and minimize aerodynamic drag. Nose cones are also designed for submerged watercraft such as submarines, submersibles and torpedoes, and in high-speed land vehicles such as rocket cars and velomobiles. Rockets On a suborbital rocket vehicle it consists of a chamber or chambers in which instruments, animals, plants, or auxiliary equipment may be carried, and an outer surface built to withstand high temperatures generated by aerodynamic heating. Much of the fundamental research related to hypersonic flight was done towards creating viable nose cone designs for the atmospheric reentry of spacecraft and ICBM reentry vehicles. In a satellite launch vehicle, the nose cone may become the satellite itself after separating from the final stage of the rocket, or it may be used as a payload fairing to shield the satellite until out of ...

Motorcycle Mechanics (magazine)
''Motorcycle Mechanics'' (Motorcycle, Scooter and Three-Wheeler Mechanics, also known as ''MM'') was a British monthly magazine founded in 1959 under Mercury House Publications. With the strapline "The illustrated how-to-do-it magazine", it initially concentrated on the practicalities of owning motorcycles as a domestic form of transport with a focus on home maintenance and repairs. Published between 1959 and 1983, many copies carried the announcements: ''World's largest sale'' and ''Largest sale''. When founding-editor Robert F Webb moved on in early 1962, successor editor Charles E Deane's message in June 1962 proudly proclaimed that, in three years from a new start, they had achieved the world's largest net sale of any motorcycle magazine. As with other motorcycling periodicals, MM moved with the times, changing its name and format to suit readership requirements and fashion and technology advancements, along with a change of ownership in 1974. In 1972 the masthead was ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isle Of Man TT
The Isle of Man TT or Tourist Trophy races are an annual motorcycle racing event run on the Isle of Man in May/June of most years since its inaugural race in 1907. The event is often called one of the most dangerous racing events in the world as many competitors have died. Overview The Isle of Man TT is run in a time-trial format on public roads closed to the public by an Act of Tynwald (the parliament of the Isle of Man). The event consists of one week of practice sessions followed by one week of racing. It has been a tradition, perhaps started by racing competitors in the early 1920s, for spectators to tour the Snaefell Mountain Course on motorcycles during the Isle of Man TT on Mad Sunday, an informal and unofficial sanctioned event held on the Sunday between Practice Week and Race Week. The first Isle of Man TT race was held on Tuesday 28 May 1907 and was called the International Auto-Cycle Tourist Trophy. The event was organised by the Auto-Cycle Club over 10 laps o ...

Nimonic
Nimonic is a registered trademark of Special Metals Corporation that refers to a family of nickel-based high-temperature low creep superalloys. Nimonic alloys typically consist of more than 50% nickel and 20% chromium with additives such as titanium and aluminium. The main use is in gas turbine components and extremely high performance reciprocating internal combustion engines. The Nimonic family of alloys was first developed in the 1940s by research teams at the Wiggin Works in Hereford, England, in support of the development of the Whittle jet engine. Development Working at Inco's Wiggin facility at Birmingham in the United Kingdom, Leonard Bessemer Pfeil is credited with the development of Nimonic alloy 80 in 1941, and used in the Power Jets W.2B. Four years later, Nimonic alloy 80A followed, an alloy widely used in engine valves today. Progressively stronger alloys were subsequently developed: Nimonic alloy 90 (1945), Nimonic alloy 100 (1955), and Nimonic alloys 105 (1960) ...

1967 Isle Of Man TT
The 1967 Isle of Man Tourist Trophy was a motorcycle road racing event held on the 37-mile Snaefell Mountain course on the Isle of Man. Five races, in different engine capacity classes of 50, 125, 250, 350 and the 500 cc Senior TT, made up the second round of the FIM World Grand Prix motorcycling championship season (now known as MotoGP). Motorcycle Hall of Fame Museum (retrieved 20 August 2006) Mike Hailwood, on the four-cylinder Honda RC181, duelled with Giacomo Agostini's MV Agusta 500 Three. The Italian broke Hailwood's lap record on the first lap at a speed of . Hailwood responded with a second lap at but Agostini still led by 8.6 seconds. At the halfway pit stop of the six-lap race, Hailwood had cut Agostini's lead to a couple of seconds, but he then lost time adjusting his twist grip back into place. Agostini's lead was back up to 11.6 seconds. It was a battle as Hailwood, riding near to his limit, pursued the Italian rider. By the fifth lap, Hailwood had ...

Castle Combe Circuit
Castle Combe Circuit is a motor racing circuit in Wiltshire, England, approximately from Bristol. The circuit is based on the perimeter track of a former World War II airfield, and was opened for racing in 1950. History The Castle Combe airfield opened in May 1941 on land of the Castle Combe estate, owned by the Gorst family, and operated as RAF Castle Combe for seven years before being decommissioned in 1948. During the war, the airfield was a training ground for pilots. From 1946 to 1948 the buildings served as a resettlement camp for Polish ex-service personnel. The property was returned to the Gorst family in 1948; with the Bristol Motorcycle & Light Car Club, they organized the first race in July 1950. By 1955 the property was divided and sold. Between 1956 and 1961, the circuit was used for motorcycle racing. Some years later, the circuit was converted to motor racing. Castle Combe has staged many different motorsport disciplines over the years. In 1997, Nigel Gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
