Rajdoot 350
The Rajdoot, also known as the RD, was a two-stroke Yamaha motorcycle made in India by Escorts group from 1983 to 1989. RD stands for 'Race derived' , in India promoted by Rajdoot in collaboration with Yamaha Japan. It is a licensed copy of the Yamaha RD350B, modified to suit Indian conditions. Even though the production of the air-cooled Yamaha RD350 had ended in Japan in the mid-1970s due to stringent emissions norms, it was a technically advanced motorcycle in the Indian market in 1983. It has a 7-port two stroke parallel twin engine, Yamaha's patented ''Torque Induction System'' using reed valves, 6-speed manual transmission, autolube system, mechanical tachometer, 12 volt electrics and 0-60 km/h in less than four seconds. In the interest of cost, the front disc brake of the RD350B was substituted with a 7" twin leading shoe drum brake from the Yamaha RD250. It was primarily targeted at the Royal Enfield Bullet 350, which was the biggest-capacity motorbike in India at the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Motorcycle Transmission
A motorcycle transmission is a transmission created specifically for motorcycle applications. They may also be found in use on other light vehicles such as motor tricycles and quadbikes, go-karts, offroad buggies, auto rickshaws, mowers, and other utility vehicles, microcars, and even some superlight racing cars. Manual gearing Most manual transmission two-wheelers use a sequential gearbox. Most motorcycles (except scooters) change gears (of which they increasingly have five or six) by a foot-shift lever. On a typical motorcycle, either first or second gear can be directly selected from neutral, but higher gears may only be accessed in order – it is not possible to shift from second gear to fourth gear without shifting through third gear. A five-speed of this configuration would be known as "one down, four up" because of the placement of the gears with relation to neutral, though some motorcycle gearboxes and/or shift mechanisms can be reversed so that a "one up, four down" shi ...

Two-stroke Motorcycles
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, 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 (automotive), 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 Scotland, Scottish engineer Dugald Clerk, who pa ...

Motorcycles Introduced In 1983
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17%) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carburetor
A carburetor (also spelled carburettor) is a device used by an internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the venturi tube in the main metering circuit, however various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American English ...

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 RX 100
The Yamaha RX 100 was a two-stroke motorcycle made by Yamaha from 1985 to 1996 with technical collaboration and distributed in India by the Escorts Group. At the initial stage, Yamaha Japan was exporting all bikes from Japan to India. After 1990, Escorts started production in India, with some parts being imported from Japan. History The RX100 designation was originally used in certain markets for the five-speed, short-stroke 97cc Yamaha RS100DX produced from 1977. This was an RS100 (itself a 1976 improvement upon the design of the original reed-valved 96cc RS100 that was introduced to the United Kingdom in September, 1974, and to the USA in November, 1974) with a front disc brake and a tachometer, and was replaced in 1983 with the square-stroke, 98cc RX-S (with part numbers coded 31J), a major update on the RS design (with substantial changes particularly to the cylinder, head, and induction, and the points ignition replaced by Yamaha Capacitor Discharge Ignition) which was to ...

Yezdi Roadking
The Yezdi Roadking was a motorcycle produced in India by Ideal Jawa Ltd, Mysore from 1978 to 1996. It was based on the CZ 250 motocross (type 980.5) ridden by Jaroslav Falta to the runner-up spot in the 1974 motocross world championship. It was sold under the brand name Yezdi. The bike won several Indian rallies and road races. The bike had a 250 cc engine with dual exhausts and a semi-automatic clutch and Jawa/CZ's trademark integrated gear shifter/kick-starter. Origins The Yezdi Roadking was the successor of the short-lived Yezdi Oilking. The Oilking was the first motorcycle in India to attempt to move away from pre-mixed fuel to a separate oil lube system via an oil pump. The box-like shape on the left hand cover housed the oil pump. Unfortunately this system had a very high failure rate resulting in piston seizures. This resulted in the discontinuation of the Oilking and the birth of the Roadking. The Roadking though, still retained the protuberance on the left engin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Enfield Bullet
The Royal Enfield Bullet was originally an overhead-valve single-cylinder four-stroke motorcycle made by Royal Enfield in Redditch, Worcestershire, now produced by Royal Enfield (India) at Chennai, Tamil Nadu, a company originally founded by Madras Motors to build Royal Enfield motorcycles under licence in India. The Royal Enfield Bullet has the longest unchanged production run of any motorcycle having remained continuously in production since 1948. The Bullet marque is even older, and has passed 75 years of continuous production. The Royal Enfield and Bullet names derive from the British company which had been a subcontractor to Royal Small Arms Factory in Enfield, London. Evolution The Bullet has evolved from a four-stroke engine with exposed valve-gear to the latest all-alloy unit construction engine with electronic fuel-injection. 1931–1939 Introduced in 1931 as a four-stroke single-cylinder motorcycle, this model was the first to feature the Bullet name.
