Chonda
A Base 50 engine is a generic term for engines that are reverse-engineered from the Honda air-cooled four-stroke single cylinder engine. Honda first offered these engines in 1958, on their Honda Super Cub 50. Honda has offered variations of this engine continuously, in sizes up to , since its introduction. The Honda Super Cub has been produced in excess of 100,000,000 units, the most successful motorized vehicle in history. With multiple manufactures utilizing clones of the Honda 50 engine for current mopeds, scooters, small motorcycles and power sport machines, it is the most produced engine in history. The engines are usually identical in form, fit and function to Honda 50cc engines and the parts are usually interchangeable with genuine Honda parts. The term Base 50 has originated from the importation of modern styled, small Pit Bikes that use the Honda CRF50 as a ''base'' for design. Base 50's have also been known as Chondas, a slang term due to influx of Honda clone en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. It is essentially the process of opening up or dissecting a system to see how it works, in order to duplicate or enhance it. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: Information extraction, Modeling, and Review. Information extraction refers to the practice of gathering all relevant information for performing the operation. Modeling refers to th ...

Centrifugal Clutch
A centrifugal clutch is an automatic clutch that uses centrifugal force to operate. The output shaft is disengaged at low rotational speed and engages more as speed increases. It is often used in mopeds, underbones, lawn mowers, go-karts, chainsaws, mini bikes, and some paramotors and boats to keep the engine from stalling when the output shaft is slowed or stopped abruptly, and to remove load when starting and idling. It has been superseded for automobile applications by the fluid coupling and automated manual transmissions. Operation The input of the clutch is connected to the engine crankshaft while the output may drive a shaft, chain, or belt. As engine revolutions per minute increase, weighted arms in the clutch swing outward and force the clutch to engage. The most common types have friction pads or shoes radially mounted that engage the inside of the rim of a housing. On the center shaft, there is an assorted number of extension springs, which connect to a clutch shoe. When ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Honda CRF Series
The Honda CRF series is a line of four-stroke motocross, trail, and dual sport motorcycles manufactured and marketed by Honda. The CRF line was launched in 2000 as a successor to the Honda CR series. The full sized motocross bikes are equipped with liquid-cooled, single cylinder four-stroke engines that are available from to . They now have dual-sport motorcycles. The more trail friendly CRF's have simple air-cooled engines, and are available from to . The Honda CRF450R was the first in the series, followed by the CRF250R in 2004. Further down the line, the CRF450X and CRF250X bikes emerged, both designed for mostly off-road use. They are considered among the best motorcross bikes of their class, and have been a leading seller since their introduction. The CRF450R was CycleWorld's Best Motocrosser for a record eight consecutive years from 2002-2009. Engine technology The engines in these bikes use an over-square design, which means that the diameter of the cylinder is l ...

Pit Bike
A pit bike is a small recreation, stunt or motocross racing motorcycle. Usually defined as having a horizontal air cooled engine and an open cradle frame. Pit bike history The pit bike evolved from the use of custom-built motorized two wheeled machines (also known as clown bikes) that began appearing during post-war 1940s and 50s pits of racing events. Initially, the term also applied to the use of bicycles or motorcycles used to navigate event staging areas. These hand-built machines were directly responsible for the creation of the Minibike Market. The fairly cheap price and the mobility of Minibikes made them easy to use at racing events. As the minibike market boomed in the 1960s, Honda introduced their own line, and the Honda Z series became popular for filling the role. With the popularity of off-road motorcycles increasing through the 1980s, inexpensive introductory-model motocross and Dual-sport bikes also began to fill this role. While determining the catalyst for pit b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honda Super Cub
The Honda Super Cub or Honda Cub is a Honda underbone motorcycle with a four-stroke single-cylinder engine ranging in displacement from . In continuous manufacture since 1958 with production surpassing 60 million in 2008, 87 million in 2014, and 100 million in 2017, the Super Cub is the most produced motor vehicle in history. Variants include the C100, C50, C70, C90, C100EX and C70 Passport, as well as the Honda Trail series. The Super Cub's US advertising campaign, ''You meet the nicest people on a Honda'', had a lasting impact on Honda's image and on American attitudes to motorcycling, and is often used as a marketing case study. Development The idea for a new motorcycle was conceived in 1956 when Honda Motor's Soichiro Honda and Takeo Fujisawa toured Germany and witnessed the popularity of mopeds and lightweight motorcycles. Soichiro Honda was primarily the engineering and production leader of the company, always with an eye towards winning on the racetrack, while his close ...

Single-cylinder Engine
A single-cylinder engine, sometimes called a thumper, is a piston engine with one cylinder. This engine is often used for motorcycles, motor scooters, go-karts, all-terrain vehicles, radio-controlled vehicles, portable tools and garden machinery (such as lawnmowers, cultivators, and string trimmers). Single-cylinder engines are made both as 4-strokes and 2-strokes. Characteristics Compared with multi-cylinder engines, single-cylinder engines are usually simpler and compact. Due to the greater potential for airflow around all sides of the cylinder, air cooling is often more effective for single cylinder engines than multi-cylinder engines. This reduces the weight and complexity of air-cooled single-cylinder engines, compared with liquid-cooled engines. Drawbacks of single-cylinder engines include a more pulsating power delivery through each cycle and higher levels of vibration. The uneven power delivery means that often a single-cylinder engine requires a heavier flywheel than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four-stroke
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 ...
