Hyosung Motors & Machinery Inc
KR Motors Co. Ltd. is a South Korean motorcycle manufacturer. History Founded in 1978 as a division of the Hyosung Group of industries, Hyosung began producing Japanese Suzuki motorcycle designs under license for the South Korean market in Changwon, South Korea in 1979. In 1986, they established their own research and development center in Hamamatsu, Japan, and the next year, they began mass production of their own designs. They were the official motorcycle supplier for the 1988 Summer Olympics in Seoul. In 2003, Hyosung Motors & Machinery Inc. was spun off from the Hyosung Group to become its own corporate entity. In June 2007, Hyosung Motors Division was acquired by Korean company S&T Group (Science and Technology), and the name was changed to S&T Motors.

Double 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 en ...

V-twin
A V-twin engine, also called a V2 engine, is a two-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. Although widely associated with motorcycles (installed either transversely or longitudinally), V-twin engines have also been used for industrial engines and in several small cars. The V-twin design dates back to the late 1880s. Origins One of the first V-twin engines was built by Gottlieb Daimler in 1889. It was used as a stationary engine, for boats and in the Daimler Stahlradwagen ("steel-wheeled car"), Daimler's second car. The engine was also manufactured under licence in France by Panhard et Levassor. An early V-twin engined motorcycle was produced in November 1902 by the Princeps AutoCar Company in the United Kingdom. The following year, V-twin motorcycles were produced by Eclipse Motor & Cycle Co in the United Kingdom (the ''XL-ALL'' model), Glenn Curtiss in the United States, and NSU Motorenwerke in Germany. ...

Cycle World
''Cycle World'' is a motorcycling magazine in the United States. It was founded in 1962 by Joe Parkhurst, who was inducted to the Motorcycle Hall of Fame as "the person responsible for bringing a new era of objective journalism" to the US. ''Cycle World'' was the largest motorcycling magazine in the world. The magazine is headquartered in Irvine, California. Regular contributors include Peter Egan and Nick Ienatsch. Previous or occasional contributors have included gonzo journalist and author Hunter S. Thompson, journalist and correspondent Henry N. Manney III, and professional riding coach Ken Hill. Parkhurst sold ''Cycle World'' to CBS in 1971. CBS executive Peter G. Diamandis and his associates bought CBS Magazines from CBS in 1987, forming Diamandis Communications, which was acquired by Hachette Magazines the following year, 1988. In 2011, Hachette sold the magazine to Hearst Corporation, which in turn sold ''Cycle World'' to Bonnier Corporation Bonnier LLC (formerl ...

Disc Brake
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. The components include the disc, master cylinder, and caliper (which contains a cylinder and two brake pads) on both sides of the disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. Other designs were not practical or widely available in cars for another 6 ...

Motorcycle
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 ...

Naked Bike
The six main types of motorcycles are generally recognized as ''standard'', ''cruiser'', ''touring'', ''sports'', ''off-road'', and ''dual-purpose''. ''Sport touring'' is sometimes recognized as a seventh category or integrated with the ''touring'' category. Although there are many names and systems for classifying types of motorcycles based on their characteristics and usage, there are generally six categories recognized by most motorcycle manufacturers and organizations. Strong distinctions are usually made between the six main types of motorcycles and other motorcycles. Scooter, moped, underbone, miniature, pocket, electric, and three-wheeled motorcycles are generally excluded from the main categories but other classification schemes may include these as types of motorcycles. There is no universal system for classifying all types of motorcycles. There are strict classification systems enforced by competitive motorcycle sport sanctioning bodies, or Legal definition of motorcyc ...

Motorcycle Fairing
A motorcycle fairing is a shell placed over the frame of a motorcycle, especially racing motorcycles and sport bikes, to deflect wind and reduce air drag. The secondary functions are the protection of the rider from airborne hazards and wind-induced hypothermia and of the engine components in the case of an accident. A motorcycle windshield will usually be integrated into the design of the fairing.Tony Foale, ''Motorcycle Handling and Chassis Design'', , Chapter 5: "Aerodynamics" The major benefit of a fairing on sport touring and touring motorcycles is a reduction in aerodynamic drag, which allows for reduced fuel consumption and permits higher speeds at lower engine rpm, which in turn increases engine life. A motorcycle may have a front fairing, a rear fairing, a belly fairing, or any combination of these. Alternatively, a single fairing may partially or fully enclose the entire motorcycle, and may even enclose the rider. History The importance of streamlining was known ver ...
