Yamaha R5
The Yamaha R5 is a motorcycle made by Yamaha for production years 1970 (R5), 1971 (R5B) and 1972 (R5C). It was the first iteration of a new generation of horizontally split crankcase two strokes that also included the RD350 and culminated in the RD400. The engine platform also included the 250cc variants (DS7/RD250). Two earlier generations of sporting 250cc and larger displacement air-cooled two strokes preceded the R5 dating back to 1959. History Yamaha began producing air-cooled "sport tuned" 250cc twin cylinder roadsters in 1959. Development led to increased capacity in 1965 to 305cc (YM1) and in 1967 to 350cc YR1. These are the ancestral predecessors to the 1970 350cc R5 and represent two different generations of engine evolution and design. The 1967 YR1, 1968 YR2 and 1969 R3 (YR3) directly preceded the R5 and were Yamaha's first publicly available 350cc capacity air-cooled, two stroke twins. The R5 was superseded by the 1973-1975 RD350 and 1976-1979 RD400. Several technical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yamaha Motor Company
is a Japanese multinational manufacturer of motorcycles, marine products such as boats and outboard motors, and other motorized products. The company was established in 1955 upon separation from Yamaha Corporation (however, Yamaha Corporation is still the largest private company shareholder with 9.92%, as of 2019), and is headquartered in Iwata, Shizuoka, Japan. The company conducts development, production and marketing operations through 109 consolidated subsidiaries as of 2012. Led by Genichi Kawakami, the company's founder and first president, Yamaha Motor spun off from musical instrument manufacturer Yamaha Corporation in 1955 and began production of its first product, the YA-1 125cc motorcycle.

RD350
The RD350 is a two-stroke motorcycle produced by Yamaha from 1973 to 1975. It evolved directly from the piston port (pre-reed valve intake tract), front drum-braked, five-speed Yamaha 350 cc "R5". The engine is an air-cooled, parallel twin, six-speed (in some markets, such as the UK, the first model was sold in five-speed form), reed valve-equipped intake tract two-stroke engine. The bike is usually referred to as a sport bike. All models were equipped with "Autolube" automatic oil injection, relieving the user from the need to mix gasoline and two-stroke oil. Rim sizes are 18" WM2 (1.85") front and 18" WM3 (2.15") rear, both being of chromed, wire spoked steel construction. In the UK, rim sizes were 1.60 front and 1.85 rear. Brakes are: single front disc brake and a rear drum brake, a combination described by ''Cycle Magazine'' as the best in its class. The frame dimensions of the street ''350'' are very similar to the Yamaha TZ 250 and TZ 350 series factory road race bikes ...

RD400
The RD400 is a two-stroke air cooled six-speed motorcycle produced by Yamaha from 1976 until 1979. It evolved directly from the Yamaha RD350 The 350 evolved into the RD400C in 1976, the "D" and "E" in '77–'78 and the final model, the white 1979 RD400F. (The model year for the first RD400, which was sold in the U.S. in the summer of 1975, was 1976.) The RD series was discontinued due to new emissions rules in the late 70's and eventually all road motorcycles were 4-stroke engines and did not burn oil with the fuel mixture to lubricate the pistons. The RD400 came with a unique self-cancelling light system that measured wheel rotations after the indicator lights were enabled. Also, for convenience, the RD did not require pre-mix fuel in the tank since it came with a 2-stroke oil pump which delivered the appropriate amount of oil when the throttle was engaged. The brakes were single disc front and rear. It could complete a standing quarter-mile in 14.01 seconds. The RD400C was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RD250
The Yamaha RD250 is a two-stroke motorcycle produced by Yamaha Motor Corporation between 1973 and 1987. Four generations of RD (also known as the RZ250 in the Japanese and Australian markets) were produced: the air-cooled models from 1973 up to 1979, and from 1980 until 1987 the liquid cooled models; known as the RD250LC, RD250LC-II and RD250 YPVS. The name RD stood for Race Developed. The standard bike weighed 152 kg dry and had a 247cc 2-stroke twin engine that produced 30 hp. It had a 6 speed gearbox and chain final drive. In 1983 the UK government reduced the maximum cc for learners to 125, killing off the 250 cc motorcycle class in a stroke. At the time, it was considered that the reason for the sudden change in the law was the RD250 which put a high-speed vehicle into the hands of inexperienced users.

Radiator (engine Cooling)
Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plant or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called ''engine coolant'' through the engine block, and cylinder head where it is heated, then through a radiator where it loses heat to the atmosphere, and then returned to the engine. Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant to circulate, and also for an axial fan to force air through the radiator. Automobiles and motorcycles In automobiles and motorcycles with a liquid-cooled internal combustion engine, a radiator is connected to channels running through the engine and cylinder head, through which a liquid (coolant) is pumped. This liquid may be water (in climates where water is unlik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kawasaki Motorcycles
Kawasaki motorcycles are manufactured by the Motorcycle & Engine division of Kawasaki Heavy Industries. History Kawasaki Aircraft initially manufactured motorcycles under the Meguro name, having bought an ailing motorcycle manufacturer, Meguro Manufacturing with whom they had been in partnership. This eventually became Kawasaki Motor Sales. Some early motorcycles display an emblem with "Kawasaki Aircraft" on the fuel tank. During 1962, Kawasaki engineers were developing a four-stroke engine for small cars. Then some of the engineers transferred to the Meguro factory to work on the Meguro K1 and the SG, a single cylinder 250 cc OHV. In 1963, Kawasaki and Meguro merged to form Kawasaki Motorcycle Co.,Ltd. Kawasaki motorcycles from 1962 through 1967 used an emblem which can be described as a flag within a wing. Work continued on the Meguro K1, a copy of the BSA A7 500 cc vertical twin. and on the Kawasaki W1. The K2 was exported to the U.S. for a test in respons ...

GT750
The Suzuki GT750 is a water-cooled three-cylinder two-stroke motorcycle made by Suzuki from 1971 to 1977. It is the first Japanese motorcycle with a liquid-cooled engine. The Society of Automotive Engineers of Japan includes the 1971 Suzuki GT750 as one of their ''240 Landmarks of Japanese Automotive Technology''. Introduction The prototype Suzuki GT750 was shown at the 17th Tokyo Motor Show in October 1970 and launched in Japan in September 1971 as a sports tourer (GT standing for Grand Tourismo) and was developed from the Suzuki T500 with an extra cylinder and liquid cooling. Marketed as the ''Le Mans'' in the US and Canada, it was nicknamed the "Kettle" in Britain, the "Water Bottle" in Australia, and the "Water Buffalo" in the United States. The GT750 was heavy at 550 lbs, with a 739 cc two-stroke three-cylinder engine with 70 mm bore and 64 mm stroke. It had a five-speed gearbox and three-into-four exhaust. 1972 model The first model year (1972), the GT ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kawasaki H2 Mach IV
The Kawasaki H2 Mach IV was a 750 cc Straight-three engine, 3-cylinder Two-stroke engine, two-stroke production motorcycle manufactured by Kawasaki motorcycles, Kawasaki. The H2 was a Kawasaki triple sold from September 1971 through 1975. A standard, factory produced H2 was able to travel a quarter mile from a standing start in 12.0 seconds. It handled better than the Mach III that preceded it. By the standards of its time, its handling was sufficient to make it the production bike to beat on the race track. Nonetheless, its tendency to pull wheelies and a less than solid feel through high speed corners led to adjustments to the design as it evolved. More than any other model, it created Kawasaki's reputation for building what motorcycle journalist Alastair Walker called, "scarily fast, good-looking, no holds barred motorcycles", and led to a further decline in the market place of the British motorcycle industry. History In September 1971 the H2 was a direct result of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
