1980 Grand Prix Motorcycle Racing Season
The 1980 Grand Prix motorcycle racing season was the 32nd F.I.M. Road Racing World Championship season. Season summary Yamaha's Kenny Roberts claimed his third successive 500cc world championship in a season shortened by the cancellations of the Venezuelan and Austrian rounds. Randy Mamola took over at Suzuki from Barry Sheene. Kawasaki returned to the 500cc class with a monocoque, four cylinder bike for Kork Ballington. Honda soldiered on with its exotic four-stroke NR500 but began to realize it was at a disadvantage against its two-stroke opposition. There were only six rounds in the 350cc class that saw South Africa's Jon Ekerold, a true privateer, take the championship from the Kawasaki factory-sponsored Anton Mang. Mang would take the 250cc crown from defending champion Ballington while Pier Paolo Bianchi won the 125cc title. Eugenio Lazzarini won a tight battle from Swiss Stefan Dörflinger to take the 50cc championship by only 2 points. 1980 Grand Prix season calen ...

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.

List Of Grand Prix Motorcycle Racing World Champions
Grand Prix motorcycle racing is the premier championship of motorcycle road racing, which has been divided into three classes since the 1990 season: 125cc, 250cc and MotoGP, with the addition of MotoE, an electric motorcycle class, in 2019. Classes that have been discontinued include 350cc and 50cc/80cc. The Grand Prix Road-Racing World Championship was established in 1949 by the sport's governing body, the Fédération Internationale de Motocyclisme (FIM), and is the oldest motorsport World Championship. There were four classes when the championship started in 1949; 500cc, 350cc, 250cc and 125cc. The 50cc class was introduced in the 1962 season. Due to escalating costs that resulted in a number of manufacturers leaving the championship, the FIM limited the 50cc bikes to a single cylinder, the 125cc and 250cc bikes were limited to two cylinders and the 350cc and 500cc bikes were limited to four cylinders. The 350cc class was discontinued in 1982; two years later the 50cc class w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Privateer (motorsport)
In motorsport, a privateer is usually an entrant into a racing event that is not directly supported by an automobile or motorcycle manufacturer. Privateers teams are often found competing in rally, circuit racing and motorcycle racing events and often include competitor Competition is a rivalry where two or more parties strive for a common goal which cannot be shared: where one's gain is the other's loss (an example of which is a zero-sum game). Competition can arise between entities such as organisms, indivi ...s who build and maintain their own vehicles and motorcycles. In previous Formula One seasons, privately owned teams would race using the chassis of another team or constructor in preference to building their own car; the Concorde Agreement now prohibits this practice. Increasingly the term is being used in an F1 context to refer to teams who are not at least part-owned by large corporations, such as Williams F1. Many privateer entrants compete for the enjoyment of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later t ...

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 ... [...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 clo ...

Kork Ballington
Hugh Neville "Kork" Ballington (born 10 April 1951) is a South African former professional motorcycle racer. He competed in the Grand Prix motorcycle racing world championships from 1976 to 1982, most prominently as a member of the Kawasaki factory racing team. The four-time FIM road racing world champion was inducted into the MotoGP Legends Hall of Fame in 2018. __TOC__ Motorcycle racing career Born in Salisbury, Southern Rhodesia, Ballington used his domestic production road racing experience as a springboard to gain entry into the British racing scene. He raced an over-the-counter Yamaha twin for several years before taking a well-earned place on the Kawasaki factory racing team riding Kawasaki KR250 and KR350s alongside Mick Grant and Barry Ditchburn. In the 250 and 350 classes, Ballington swept away the competition on his Kawasakis in 1978 and 1979, capturing consecutive double world championships. In 1980, he campaigned Kawasaki's new KR500 but developing a ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of which ...
