Yamaha TD3
Yamaha TD2 is an air-cooled road racing motorcycle made by Yamaha produced between 1969 and 1970. The equivalent 350cc version was called TR2 Development The TD1 bikes had a significant impact on British 250cc class racing in the middle-1960s which was historically contested by single-cylinder engines, some with ageing designs. Some TD1s were overbored to 251cc, thus being eligible for the 350cc class Building on the TD1 successes, the arrival of TD2 together with the TR2 350cc version which could be overbored to around 352cc, making it eligible for the 500cc class, announced the 'death knell' of the traditional 350cc and 500cc class single-cylinder four stroke engines manufactured to 1950s designs The new over-the-counter Yamahas were smaller, lighter with greater maneuverability and consequently easier braking. The engines were simpler to build - but not significantly easier to maintain as four-stroke singles potentially lasted an entire season - offering a small compact uni ...

The Motor Cycle
''The Motor Cycle'' was one of the first British magazines about motorcycles. Launched by Iliffe and Sons Ltd in 1903, its blue cover led to it being called "The Blue 'un" to help distinguish it from its rival publication ''Motor Cycling (magazine), Motor Cycling'', which, using a green background colour, was known as "The Green 'un". Many issues carried the strapline "Circulated throughout the World". The covers eventually used a variety of different background colours after 1962, with a name-change to ''Motor Cycle''. Features Noted for detailed road tests of contemporary motorcycles and articles on readers' bikes, the magazine had regular features, including "Current Chat" and "Letters to the Editor" where many of the key issues relating to British motorcycling of the day were debated. The contributors often signed their pieces with pseudonyms such as ''Torrens'' (Arthur Bourne, one of the Editors) and the famous ''Ixion'' (Canon B.H. Davies). Recent history From 1962, ...

Norton Manx
The Norton Manx or Manx Norton is a British racing motorcycle that was made from 1947 to 1962 by Norton Motors Ltd. Norton had contested every Isle of Man TT race from the inaugural 1907 event through into the 1970s, a feat unrivalled by any other manufacturer, and the development and honing of the Manx racing motorcycle was another step in this racing achievement. New Manx Nortons, built to various specifications are still available to buy new, from various suppliers around the world. These should not be confused with Norton production motorcycles even though they suit different categories and definitions of Classic Motorcycle Racing and Historic Motorcycle Racing in different countries around the world. Norton's first use of the name 'Manx' was applied to the 'Manx Grand Prix' model available from 1936-1940, a special racing version of their 'International' roadster, with telescopic forks and a plunger rear suspension, magnesium for the crankcases and cambox, and no provisi ...

Bultaco
Bultaco was a Spanish manufacturer of two-stroke motorcycles from 1958 to 1983. In May 2014, a new Bultaco was announced. Origins The origin of the Bultaco motorcycle company dates from May 1958. Francesc "Paco" Bultó was a director of the Montesa motorcycle company, founded in 1944. After several years of steady growth and road racing success, in 1957 Montesa moved to larger facilities. The move was protracted, disrupting production and was followed by a downturn in the Spanish economy. This slump brought to a head disagreements between Bultó and the other senior director Pere Permanyer. As an economy measure, Permanyer (the majority shareholder) felt that the company should withdraw from racing. Bultó, the driving force behind the racing program and responsible for much of the company’s technical expertise was vehemently opposed. Failing to reach a compromise, Bultó decided to leave Montesa to concentrate on his other business interests. Perhaps unsurprisingly, the maj ...

Aermacchi
Aermacchi was an Italian aircraft manufacturer. Formerly known as Aeronautica Macchi, the company was founded in 1912 by Giulio Macchi at Varese in north-western Lombardy as Nieuport-Macchi, to build Nieuport monoplanes under licence for the Italian military. With a factory located on the shores of Lake Varese, the firm originally manufactured a series of Nieuport designs, as well as seaplanes. After World War II, the company began producing motorcycles as a way to fill the post-war need for cheap, efficient transportation. The company later specialised in civil and military pilot training aircraft. In July 2003, Aermacchi was integrated into the Finmeccanica Group (now Leonardo) as Alenia Aermacchi, which increased its shareholding to 99%. Military trainers Since the beginning, the design and production of military trainers have been the core business of Alenia Aermacchi. The products include: * SF-260, piston-engined or turboprop-powered screener/primary trainer * MB ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Compression Ratio
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it is measured two ways: the static compression ratio, calculated based on the relative volumes of the combustion chamber and the cylinder when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to ...
