Kawasaki H2R
The Kawasaki H2R was a racing motorcycle built by Kawasaki from 1972 to 1974. It was based on the road going Kawasaki H2 Mach IV air cooled, two stroke triple. In 1975 it was replaced by a water cooled development, the Kawasaki KR750. Timeline 1971 The AMA had announced that the regulations for 1972 had been changed to allow 750 cc two strokes to compete in 750 cc class, leading Kawasaki to develop a race version of the road-going H2. The engine was powerful but fragile. The chassis of the H2R was derived from the chassis used on the H1R which had been derived from the Kawasaki 250 racers and was effectively an enlargement of the 1968 125 cc frame. This frame had been based on the Norton Featherbed. To overcome the vibration of the larger engines, the engine was rubber-mounted which affected the stiffness of the frame as the engine was no longer contributing to its rigidity. The H2 was thirsty, initially only giving 10 mpg, and would therefore need to stop to refuel in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formula 750
Formula 750 was a FIM motorcycle road racing series based on a 750 cubic centimeter engine capacity. History The series began in 1971 as a collaboration between the American Motorcyclist Association and the Auto Cycle Union. The FIM adopted the Formula 750 class for events in 1972. In 1973 it became a British-based series. In 1975 the series was upgraded to European championship status and in 1977, it attained world championship status. The Formula 750 class was seen as possibly overtaking the 500cc Grand Prix class as the premier racing division. However, the ultimate domination by one model (the Yamaha TZ750) as well as the increasingly popular superbike A sport bike (sports motorcycle, or sports bike) is a motorcycle designed and optimized for speed, acceleration, braking, and cornering on asphalt concrete race tracks and roads.

Inline-three Engine
A straight-three engine (also called an inline-triple or inline-three) is a three-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. Less common than straight-four engines, straight-three engines have nonetheless been used in various motorcycles, cars and agricultural machinery. Design A crankshaft angle of 120 degrees is typically used by straight-three engines, since this results in an evenly spaced firing interval. Another benefit of this configuration is perfect primary balance and secondary balance, however an end-to-end rocking couple is induced because there is no symmetry in the piston velocities about the middle piston. A balance shaft is sometimes used to reduce the vibrations caused by the rocking couple. Other crankshaft angles have been used occasionally. The 1976-1981 Laverda Jota motorcycle used a 180 degree crankshaft, where the outer pistons rise and fall together and inner cylinder is offset from them by 180 degrees. T ...

Two-stroke Engine
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 two ...

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Motorcyclist Association
The American Motorcyclist Association (AMA) is an American nonprofit organization of more than 200,000 motorcyclists that organizes numerous motorcycling activities and campaigns for motorcyclists' legal rights. Its mission statement is "to promote the motorcycling lifestyle and protect the future of motorcycling." The organization was founded in 1924 and as of October 2016 had more than 1,100 chartered clubs.

Brake
A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction. Background Most brakes commonly use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat, though other methods of energy conversion may be employed. For example, regenerative braking converts much of the energy to electrical energy, which may be stored for later use. Other methods convert kinetic energy into potential energy in such stored forms as pressurized air or pressurized oil. Eddy current brakes use magnetic fields to convert kinetic energy into electric current in the brake disc, fin, or rail, which is converted into heat. Still other braking methods even transform kinetic energy into different forms, for example by transferring the energy to a rotating flywheel. Brakes are gene ...

Motorcycle Fork
A motorcycle fork connects a motorcycle's front wheel and axle to its frame, typically via a yoke, also known as a triple clamp, which consists of an upper yoke joined to a lower yoke via a steering stem, a shaft that runs through the steering head, creating the steering axis. Most forks incorporate the front suspension and front brake, and allow the front wheel to rotate about the steering axis so that the bike may be steered. Most handlebars attach to the top clamp in various ways, while clip-on handlebars clamp to the fork tubes, either just above or just below the upper triple clamp. The fork and its attachment points on the frame establish the critical geometric parameters of rake and trail, which play a major role in defining how a motorcycle handles and dives during braking. While the standard telescopic fork arrangement is found with few major differences among mainstream street motorcycles since the 1970s, historically there have been many variations, including trail ...

Grand Prix Motorcycles
Grand Prix motorcycle racing is the premier class of motorcycle road racing events held on road circuits sanctioned by the Fédération Internationale de Motocyclisme (FIM). Independent motorcycle racing events have been held since the start of the twentieth century and large national events were often given the title Grand Prix. The foundation of the Fédération Internationale de Motocyclisme as the international governing body for motorcycle sport in 1949 provided the opportunity to coordinate rules and regulations in order that selected events could count towards official World Championships. It is the oldest established motorsport world championship. Grand Prix motorcycles are purpose-built racing machines that are unavailable for purchase by the general public and unable to be ridden legally on public roads. This contrasts with the various production-based categories of racing, such as the Superbike World Championship and the Isle of Man TT Races that feature modified ver ...

Kawasaki Triples
The Kawasaki triples were a range of ' motorcycles made by Kawasaki from 1968 to 1980. The engines were air-cooled, three-cylinder, piston-controlled inlet port two-strokes with two exhaust pipes exiting on the right side of the bike, and one on the left. It was the first production street motorcycle with capacitor discharge ignition (CDI). Right from the first triple model, the 1968 Mach III H1 ''500 cc'', it was a sales success that gained a reputation for almost unmatched acceleration as well as an air of danger for inexperienced riders trying to cope with the bike's increased power to weight ratio over any previously available stock motorcycles. Mach III H1 500 The market for motorcycles in 1968 was changing from utilitarian transport to more aggressive sporting motorcycles that disregarded fuel economy and noise, in favor of quicker quarter mile times, which were prominently advertised by manufacturers. While Kawasaki had an inline-four four-stroke in development, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
