Fédération Internationale De Motocyclisme
The Fédération Internationale de Motocyclisme (FIM; en, International Motorcycling Federation) is the global governing/sanctioning body of motorcycle racing. It represents 116 national motorcycle federations that are divided into six regional continental unions. There are seven motorcycle-racing disciplines that FIM covers, encompassing 82 world championships as well as hundreds of secondary championships: enduro, trial, circuit racing, motocross and supermoto, cross-country, e-bike, and track racing. FIM is also involved in many non-racing activities that promote the sport, its safety, and support relevant public policy. The FIM is also the first international sporting federation to publish an Environmental Code, in 1994. In 2007, a Commission for Women in Motorcycling was created by the FIM in order to promote the use of powered two-wheelers and the motorcycle sport among women.

Antonio Cobas
Antonio Cobas (Barcelona 1952 – April 14, 2004) was a Spanish Grand Prix motorcycle designer, constructor and mechanic who built world championship winning motorcycles. Cobas was credited with being the originator of the modern, aluminum frame chassis now used on many modern racing and production motorcycles. In the early 1980s, racing motorcycles still used steel-tubed frames developed in the 1950s. As motorcycle engine and tire technology progressed, motorcycle frames became more and more stressed. In 1982, Cobas developed a stronger and lighter aluminum twin-beam chassis to replace the steel backbone frames. The technology was copied by major motorcycle manufacturers and by the 1990s, all the major racing teams in Grand Prix competition used the aluminum frame design pioneered by Cobas. Cobas began constructing racing motorcycles named Sirokas in 1978, which were successful in the Spanish road race national championships. In 1982, he created the Kobas brand motorcycle designi ...

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''".

Motorcycle Frame
A motorcycle frame is a motorcycle's core structure. It supports the engine, provides a location for the steering and rear suspension, and supports the rider and any passenger or luggage. Also attached to the frame are the fuel tank and battery. At the front of the frame is found the steering head tube that holds the pivoting front fork, while at the rear there is a pivot point for the swingarm suspension motion. Some motorcycles include the engine as a load-bearing stressed member; while some other bikes do not use a single frame, but instead have a front and a rear subframe attached to the engine. Materials In the early days, motorcycles were little more than motorised bicycles, and consequently frames were tubular steel. While the use of steel tubing is still common, in modern times other materials, such as titanium, aluminium, magnesium, and carbon-fibre, along with composites of these materials, are now used. As different motorcycles have varying design parameters (such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angel Nieto
In various theistic religious traditions an angel is a supernatural spiritual being who serves God. Abrahamic religions often depict angels as benevolent celestial intermediaries between God (or Heaven) and humanity. Other roles include protectors and guides for humans, and servants of God. Abrahamic religions describe angelic hierarchies, which vary by religion and sect. Some angels have specific names (such as Gabriel or Michael) or titles (such as seraph or archangel). Those expelled from Heaven are called fallen angels, distinct from the heavenly host. Angels in art are usually shaped like humans of extraordinary beauty. They are often identified in Christian artwork with bird wings, halos, and divine light. Etymology The word ''angel'' arrives in modern English from Old English ''engel'' (with a hard ''g'') and the Old French ''angele''. Both of these derive from Late Latin ''angelus'', which in turn was borrowed from Late Greek ''angelos'' (literally "messenge ...

1975 Grand Prix Motorcycle Racing Season
The 1975 Grand Prix motorcycle racing season was the 27th F.I.M. Road Racing World Championship season. Season summary 1975 represented a changing of the guard in Grand Prix motorcycle racing, both for riders as well as machines. Giacomo Agostini would claim his final 500cc World Championship aboard a Yamaha two-stroke machine. This would also mark the first time a two-stroke machine had won the premier division. Angel Nieto claimed his fourth world title for Kreidler in the 50cc class. In the 125cc division, the Morbidellis of Pileri and Bianchi dominated, finishing first and second in six of the ten events. Despite Michel Rougerie scoring more points, his Harley-Davidson teammate Walter Villa would take the 250cc title because of the "best of six finishes" rule. Nineteen-year-old newcomer Johnny Cecotto made an impressive debut at the season opening French Grand Prix where, he won the 250cc and 350cc races. He went on to claim the 350cc title, becoming the youngest-ever FIM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michel Rougerie
Michel Rougerie (21 April 1950 in Montreuil-sous-Bois - 31 May 1981 in Rijeka) was a French professional motorcycle racer. He competed in the Grand Prix road racing world championships from 1972 to 1981. His best year was in 1975 when he won two races and finished in second place in the 250cc world championship behind his Harley-Davidson team-mate Walter Villa. Rougerie actually scored more points than Villa that season, but because only the best six results of the season were counted, he lost the championship. He was killed in 1981 because he was hit by another racer while competing at the Yugoslavian Grand Prix.

British Motorcycle Grand Prix
The British motorcycle Grand Prix is a motorcycling event that is part of the Grand Prix motorcycle racing season. History Before 1977, the only British round was the Isle of Man TT, which was part of the FIM championship from its inauguration in 1949 until 1976. The Isle of Man TT was the most prestigious event on the Grand Prix motorcycling calendar from 1949 to 1972. After the 1972 event, multiple world champion Giacomo Agostini dropped a bombshell on the motorsports world by stating he would never race at the Isle of Man TT again, saying the 37-mile (62 km) circuit was too dangerous for international competition. His friend Gilberto Parlotti was killed during the event. Many riders followed Agostini's boycotting of the next four events, and after the 1976 season, the Isle of Man TT was scratched from the FIM calendar. The inaugural British motorcycle Grand Prix, the first motorcycle Grand Prix to be held on the British mainland, took place at the Silverstone Circu ...

Honda NR500
NR500 was a racing motorcycle developed by Honda HRC in 1979 to compete in Grand Prix motorcycle racing. "NR" stands for "New Racing". Model history The motivation behind the NR500 was company founder Soichiro Honda's desire to compete using four-stroke engine technology since the majority of motorcycles manufactured by Honda used four-stroke engines. When the FIM announced new regulations for the 1968 Grand Prix motorcycle racing season that limited the 500 cc engines to four cylinders, this gave an advantage to teams using two-stroke machinery. Honda decided to withdraw from motorcycle racing to concentrate on its automobile division. In November 1977 Honda announced it would be returning to motorcycle Grand Prix racing using four-stroke technology. Even though two-stroke engines dominated motorcycle Grand Prix racing in the late 1970s, Honda felt compelled to race what they sold and thus competed using a high-technology, four-stroke race bike. Since a conventional fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four-stroke
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...
