Meguro Motorcycles
Meguro motorcycles were built by Meguro Manufacturing Co motorcycle works (目黒製作所), founded by Nobuji Murata and a high-ranking naval officer, Takaji Suzuki, in 1937. One of the first Japanese motorcycle companies, it became a partner of Kawasaki Heavy Industries Ltd, and was eventually absorbed. Named after a district of Tokyo, Meguro had its roots in Murato Iron Works, which was established in 1924. Meguro Seisakusho, which had once developed a copy of a Harley-Davidson V-twin, was established to design and build gearboxes for the nascent Japanese motorcycle industry. Abe Industries, which had once produced its own motorcycle, merged with Meguro in 1931. The brand is being revived by Kawasaki with a new K3 model to be introduced in Japan on February 1, 2021. Once a prestige brand, supplying the Japanese government with military and police motorcycles, and racing alongside Honda, Meguro (メグロ) became bankrupt after launching a range of lightweight motorcycles wh ...

Pre-unit Construction
Pre-unit construction, also called separate construction, is a motorcycle engine architecture where the engine and gearbox are separate components with their own oil reservoirs, linked by a driving chain within a primary chaincase. Mounting plates are usually attached to the frame allowing for chain adjustment by gearbox fore-and-aft movement and via screw adjusters and elongated mounting holes. Even though Singer offered an integrated engine and gearbox in a single casing in 1911, it was not until the 1950s that technical advances meant it was possible to reliably construct engines with integral gearboxes in a single unit, known as unit construction. Another variant is semi-unit construction, where the gearbox is bolted directly to the engine. Curiously, early BSA A10 and A7 parallel twins (650cc and 500 cc, respectively) were semi-unit construction, but the factory later adopted pre-unit construction. The term "pre-unit" was coined only after such engines were succeeded by "u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kawasaki W Series
The Kawasaki ''W'' series is a line of motorcycles made by Kawasaki since 1965 that shares some characteristics of classic British vertical-twin standard motorcycles. Sold as a 1966 model in the North American market, the first Kawasaki W1 had the largest engine displacement of any model manufactured in Japan at the time. Kawasaki continued to build models of the ''W'' brand similar to the W1 which will go out of production, ending with a "final edition". Antecedents: Meguro K series In 1960 the Akashi-based Kawasaki Aircraft Company acquired an interest in the Meguro motorcycle company, which had obtained a license to produce a copy of the 500 cc BSA A7. Meguro had been Japan's largest motorcycle manufacturer but in the late 1950s its models had become less competitive and it was short of money. Kawasaki's investment enabled Meguro to launch its A7 copy as the Meguro K. The BSA A7, Meguro K and their respective derivatives have an overhead valve (i.e., pushrod) straight ...

Heavy Industry
Heavy industry is an industry that involves one or more characteristics such as large and heavy products; large and heavy equipment and facilities (such as heavy equipment, large machine tools, huge buildings and large-scale infrastructure); or complex or numerous processes. Because of those factors, heavy industry involves higher capital intensity than light industry does, and it is also often more heavily cyclical in investment and employment. Though important to economic development and industrialization of economies, heavy industry can also have significant negative side effects: both local communities and workers frequently encounter health risks, heavy industries tend to produce byproducts that both pollute the air and water, and the industrial supply chain is often involved in other environmental justice issues from mining and transportation. Because of their intensity, heavy industries are also significant contributors to greenhouse gas emissions that cause climat ...

Motorcycle Speedway
Motorcycle speedway, usually referred to simply as speedway, is a motorcycle sport involving four and sometimes up to six riders competing over four anti-clockwise laps of an oval circuit. The motorcycles are specialist machines that use only one gear and have no brakes. Racing takes place on a flat oval track usually consisting of dirt, loosely packed shale, or crushed rock (mostly used in Australia and New Zealand). Competitors use this surface to slide their machines sideways, powersliding or broadsiding into the bends. On the straight sections of the track, the motorcycles reach speeds of up to . There are now both domestic and international competitions in a number of countries, including the Speedway World Cup, whilst the highest overall scoring individual in the Speedway Grand Prix events is pronounced the world champion. Speedway is popular in Central and Northern Europe and to a lesser extent in Australia and North America. A variant of track racing, speedway is adm ...

Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ... [...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 ...

Edward Turner (motorcycle Designer)
Edward Turner (24 January 1901 – 15 August 1973) was an English motorcycle designer. He was born in Camberwell in the London Borough of Southwark, on the day King Edward VII was proclaimed King. In 1915, Turner had his first ride on a motorcycle, a Light Tourist New Imperial. Turner Special On 16 April 1925 "The Motor Cycle" published drawings by Turner of an OHC single he had designed, using a series of vertically stacked gears to drive the overhead camshaft. A subsequent redesign used bevel gears to drive a vertical camshaft, operating the valves through rockers. The only shared aspects of the two designs were the bore and stroke, , with the barrel being sunk into the crankcases. The head could be removed from either design complete with undisturbed valve gear. Turner built his first bike in 1927, using his second design, a 350 cc OHC single. ''The Motor Cycle'' published a photograph of Turner's patented engine, mounted in his motorcycle called the Turner Specia ...
