Yamaha YZF-R7 (2022 Bike)
The Yamaha YZF-R7 is a super sport motorcycle based on the MT-07 platform. On May 18, 2021 Yamaha announced the motorcycle, sharing a name with the 1999 YZF-R7 race homologation bike. The 2022 motorcycle is a mid capacity powered by a 54.7 kW (73 hp) liquid cooled four-stroke inline two cylinder double overhead cam 689cc engine. It features forged aluminum pistons with direct plated cylinders integrated with the crankcase. The R7's reliable crossplane engine's 270 degree crank provides an uneven firing sequence, which is designed to deliver a more characterful note and emphasize torquey acceleration and power delivery. The engine is updated in 2021 to be Euro 5 The European emission standards are vehicle emission standards for pollution from the use of new land surface vehicles sold in the European Union and EEA member states and the UK, and ships in EU waters.

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. It was quickly successful and won the 3rd Mount Fuji Ascent Race in its class. The company's products include motorcycles, scooters, motorized bicycles, boats, sail boats, personal water craft, swimming pools, utility boats, fishing boats, outboard motors, 4-wheel ATVs, recreat ...

Motorcycle Suspension
A motorcycle's suspension serves a dual purpose: contributing to the vehicle's handling and braking, and providing safety and comfort by keeping the vehicle's passengers comfortably isolated from road noise, bumps and vibrations. The typical motorcycle has a pair of fork tubes for the front suspension, and a swingarm with one or two shock absorbers for the rear suspension. Front suspension The most common form of front suspension for a modern motorcycle is the telescopic fork. Other fork designs are girder forks, suspended on sprung parallel links (not common since the 1940s) and bottom leading link designs, not common since the 1960s. Some manufacturers (e.g. Greeves) used a version of the swinging arm for front suspension on their motocross designs. A single-sided version of the idea is also used in motor scooters such as the Vespa. The hub-center steering as developed by Ascanio Rodorigo, on a concept associated to Massimo Tamburini is a complex front swingarm alternat ...

Crossplane
The crossplane or cross-plane is a crankshaft design for piston engines with a 90° angle (phase in crank rotation) between the crank throws. The crossplane crankshaft is the most popular configuration used in V8 road cars. Aside from the V8 already mentioned, other examples of configurations using such 90° piston phases include straight-2, straight-4, V2, and V4 engines. Crossplane crankshafts could feasibly be used with a great many other cylinder configurations, but the advantages and disadvantages described below may not apply to any or all of them and must be considered on a case-by-case basis. Crossplane V8 crankshaft Design The most common crossplane crankshaft for a 90° V8 engine has four crankpins, each serving two cylinders on opposing banks, offset at 90° from the adjacent crankpins. The first and last of the four crank pins are at 180° with respect to each other as are the second and third, with each pair at 90° to the other, so that viewed from the end the ...

Forging
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.Degarmo, p. 389 Forging has been done by smiths for millennia; the traditional products were kitchenware, hardware, hand tools, edged weapons, cymbals, and jewellery. Since the Industrial Revolution, forged parts are widely used in mechanisms and machines wherever a component requires high strength; such forgings usually require further processing (such as machining) to achieve a finished part. Today, forging is a major worldwide industry. History Forging is one of the oldest known me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two Cylinder
The engine configuration describes the fundamental operating principles by which internal combustion engines are categorized. Piston engines are often categorized by their cylinder layout, valves and camshafts. Wankel engines are often categorized by the number of rotors present. Gas turbine engines are often categorized into turbojets, turbofans, turboprops and turboshafts. Piston engines Piston engines are usually designed with the cylinders in lines parallel to the crankshaft. It is called a straight engine (or 'inline engine') when the cylinders arranged in a single line. Where the cylinders are arranged in two or more lines (such as in V engines or flat engines), each line of cylinders is referred to as a 'cylinder bank'. The angle between cylinder banks is called the 'bank angle'. Engines with multiple banks are shorter than straight engines and can be designed to cancel out the unbalanced forces from each bank, in order to reduce the vibration. Most engines w ...

Four-stroke Engine
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are close ...

Liquid Cooling
Liquid cooling refers to cooling by means of the convection or circulation of a liquid. Examples of liquid cooling technologies include: * Cooling by convection or circulation of coolant, including water cooling * Liquid cooling and ventilation garments, worn by astronauts * Liquid metal cooled reactors * Radiators (engine cooling) * Cooling towers Applications Computing In computing and electronics, liquid cooling involves the technology that uses a special water block to conduct heat away from the processor as well as the chipset. This method can also be used in combination with other traditional cooling methods such as those that use air. The application to microelectronics is either indirect or direct. The former pertains to the category that utilizes cold plate cooling, which uses water as coolant while, in the latter (also referred to as liquid immersion cooling), the surface of the chips comes in contact with the liquid since there is no wall separating the heat sour ...

Homologation (motorsport)
In motorsports, homologation is the type approval process through which a vehicle, a race track, or a standardised part is required to go for certification to race in a given league or series. The process of testing and certification for conformance to technical standards is usually known as type approval in English-language jurisdictions. The regulations and rules that must be met are generally set by the series's sanctioning body. The word is derived from Greek , . When a car loses the homologation form, that is, it becomes a historic vehicle, it can no longer be part of a competition and can only be used in historic competitions. Requirements In racing series that are "production-based", meaning that the vehicles entered in the series are based on production vehicles for sale to the public, homologation not only requires compliance with a racing series's technical guidelines (for example engine displacement, chassis construction, suspension design and such), but often i ...

Super Sport (motorcycle)
A sport bike (sports motorcycle, or sports bike) is a motorcycle designed and optimized for speed, acceleration, braking, and cornering on asphalt concrete race tracks and roads. They are mainly designed for performance at the expense of comfort, fuel economy, and storage in comparison with other motorcycles. Sport bikes can be and are typically equipped with fairings and a windscreen to deflect wind from the rider to improve aerodynamics. Soichiro Honda wrote in the owner's manual of the 1959 Honda CB92 Benly Super Sport that, "Primarily, essentials of the motorcycle consists in the speed and the thrill," while '' Cycle World''s Kevin Cameron says that, "A sportbike is a motorcycle whose enjoyment consists mainly from its ability to perform on all types of paved highway – its cornering ability, its handling, its thrilling acceleration and braking power, even (dare I say it?) its speed." Motorcycles are versatile and may be put to many uses as the rider sees fit. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
