Rikuo Internal Combustion Engine
was one of the first motorcycle manufacturing companies in Japan. In the early 1930s Rikuo operated under the license and name of Harley-Davidson, using their tooling, and later under the name Rikuo until 1958. Harley-Davidson themselves did not publicize this Japanese connection because the Japanese were helped in developing mass-production techniques by the introduction of this factory into Japan just prior to the Second World War. The Society of Automotive Engineers of Japan rates the 1935 Rikuoh Large Motorcycle as one of their 240 Landmarks of Japanese Automotive Technology. History The production of the Harley-Davidson in Japan resulted in large part from the United Kingdom's McKenna Tariffs modification of 1921. In 1921 the Safeguarding of Industries act placed duties of 33.3 percent on 6500 items. The tariffs were put into place to protect UK industry and levied a steep import duty against the American brands which were seen as damaging the UK motorcycle industry. ...

Daiichi Sankyo Co
(第一) is a compound modifier phrase of Japanese origin, meaning ''number one'', or ''first''. In kanji, "dai" ("number") is 第Nakao, Seigo''Random House Japanese-English English-Japanese Dictionary'' via Google Books, p. 39. Retrieved 2011-03-18. and "ichi" ("one") is 一.Nakao, Seigo''Random House Japanese-English English-Japanese Dictionary'' via Google Books, p. 95. Retrieved 2011-03-18. "Dai" is also defined " ordinal number marker." It is this feature that makes the phrase a modifier, or an adjective, describing a noun, as ''first''. ''Number one'' functions in the same way. The phrase is also written without the hyphen, as daiichi. Dai-ichi is frequently used in proper names, hence capitalized; also Dai-Ichi and occasionally Dai Ichi.

Motorcycles Of Japan
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 (1 ...

Kilogram
The kilogram (also kilogramme) is the unit of mass in the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo colloquially. It means 'one thousand grams'. The kilogram is defined in terms of the second and the metre, both of which are based on fundamental physical constants. This allows a properly equipped metrology laboratory to calibrate a mass measurement instrument such as a Kibble balance as the primary standard to determine an exact kilogram mass. The kilogram was originally defined in 1795 as the mass of one litre of water. The current definition of a kilogram agrees with this original definition to within 30 parts per million. In 1799, the platinum ''Kilogramme des Archives'' replaced it as the standard of mass. In 1889, a cylinder of platinum-iridium, the International Prototype of the Kilogram (IPK), became the standard of the unit of mass for ...

Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . In ...

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

Showa Corporation
is a manufacturer of high-performance automotive, motorcycle and outboard suspension systems based in Gyoda, Saitama in Japan. The company was founded in 1938 as Showa Aircraft Precision Works. In Japan's drive to develop its military capability in preparation foWorld War II Showa supplied aircraft suspension and landing systems to various aircraft manufacturers. Banned from developing or manufacturing aircraft systems after the war, Showa entered the car components industry, using its aircraft knowledge to develop specialist suspension products for motorcycles made by the new company Honda. The relationship between Showa and Honda developed over the years, with Honda Racing Corporation accounting for more than 50% of Showa's business. In 1950 Showa acquired Rikuo Motorcycle, which made licensed versions of Harley Davidson motorcycles in the 1930s and 1940s. Rikuo brand lasted until 1962. Showa has since become OEM supplier to Harley Davidson. Showa has overseas facilities ...

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 trailin ...

Sidecar
A sidecar is a one-wheeled device attached to the side of a motorcycle, scooter, or bicycle, making the whole a three-wheeled vehicle. A motorcycle with a sidecar is sometimes called a ''combination'', an ''outfit'', a ''rig'' or a ''hack''. History Jean Bertoux, a French army officer, secured a prize offered by a French newspaper in 1893 for the best method of carrying a passenger on a bicycle. The sidecar wheel was mounted on the same lateral plane as the bicycle's rear and was supported by a triangulation of tubes from the bicycle. A sprung seat with back rest was mounted above the cross-member and a footboard hung below. A sidecar appeared in a cartoon by George Moore in the January 7, 1903, issue of the British newspaper '' Motor Cycling''. Three weeks later, a provisional patent was granted to Mr. W. J. Graham of Graham Brothers, Enfield, Middlesex. He partnered with Jonathan A. Kahn to begin production. One of Britain's oldest sidecar manufacturers, Watsonian, was fou ...

Holding Company
A holding company is a company whose primary business is holding a controlling interest in the securities of other companies. A holding company usually does not produce goods or services itself. Its purpose is to own shares of other companies to form a corporate group. In some jurisdictions around the world, holding companies are called parent companies, which, besides holding stock in other companies, can conduct trade and other business activities themselves. Holding companies reduce risk for the shareholders, and can permit the ownership and control of a number of different companies. ''The New York Times'' also refers to the term as ''parent holding company.'' Holding companies are also created to hold assets such as intellectual property or trade secrets, that are protected from the operating company. That creates a smaller risk when it comes to Lawsuit, litigation. In the United States, 80% of stock, in voting and value, must be owned before tax consolidation benefits s ...
