ATC250R
The ATC250R is a high-performance, three-wheeled ATV produced by Honda from 1981 to 1986. Cited at the first high performance ATC introduced, production began with an air-cooled, 248 cc single-cylinder two-stroke engine, but would see a liquid-cooled, 246 cc engine by 1985. All model years were fully suspended and adjustable, using air-assisted front forks and a single, remote reservoir gas-charged rear shock. 1981-1982 models offered 6.7 inches of front suspension travel and 4.3 inches in the rear, 1983-1984 offered 8.7 inches in front and 8.1 inches rear, while post-1985 Models allowed 9.8 inches of travel. All model years also used a gear-driven counter-balancer to reduce engine vibration. Dual disc brakes were used on all model years, with the exception of the 1981, which used a front disc and a rear drum. 1st Generation (1981-1982) The introduction of the 1981 ATC250R marked a milestone in off-road history, as it was the first two-stroke ATC designed specifica ...

Honda Sport ATCs
Honda Sport ATCs, produced until 1987, were built specifically for performance, and designed for use in racing, or for aggressive trail riding. The machines lacked luggage racks and other utilitarian features, commonplace on most other ATCs or ATVs. In 1970, Honda created the three-wheeled “All Terrain Cycle” market nearly single-handedly with the release of the Honda US90. As the popularity of ATCs exploded in the late seventies, Honda began to diversify their line. Originally catering to winter activity, campers, hunters and weekend Recreational riders that ATCs were envisioned for, their research showed there was a market for utility-focused machines for commercial and agricultural use, and dedicated sport models intended for leisure and competition use. This led to the creation of the ATC250R The ATC250R is a high-performance, three-wheeled ATV produced by Honda from 1981 to 1986.

All-terrain Vehicle
An all-terrain vehicle (ATV), also known as a light utility vehicle (LUV), a quad bike, or simply a quad, as defined by the American National Standards Institute (ANSI); is a vehicle that travels on low-pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. Although it is a street-legal vehicle in some countries, it is not street-legal within most states, territories and provinces of Australia, the United States or Canada. By the current ANSI definition, ATVs are intended for use by a single operator, although some companies have developed ATVs intended for use by the operator and one passenger. These ATVs are referred to as tandem ATVs. The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more stability at slower speeds. Although most are equipped with three or four wheels, six-wheel mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honda TRX250R
The Honda TRX250R was a sport ATV manufactured by Honda between 1986 and 1989. It combined a lightweight frame and good handling, with a liquid-cooled two-stroke engine and six-speed close-ratio transmission. Although only being manufactured for four years, the "250R", as it was known, was long a primary choice for ATV racers until the resurgence of factory involvement and usage of four-stroke engines in sport ATV's beginning in 2003 and 2004. Specifications Generations The TRX250R was introduced for the 1986 model year to answer Suzuki’s LT250R, released the year prior. Honda borrowed many parts from its 3 wheel ATC250R for the Fourtrax’s design, including the engine and rear suspension. Although mechanically similar, Honda detuned the engine for use in the Fourtrax, through reduced compression and less aggressive porting, to ensure that the added weight of the quad would not adversely affect the reliability of the engine. The 1987 model year, now absent the three- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radiator (engine Cooling)
Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plant or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called '' engine coolant'' through the engine block, and cylinder head where it is heated, then through a radiator where it loses heat to the atmosphere, and then returned to the engine. Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant to circulate, and also for an axial fan to force air through the radiator. Automobiles and motorcycles In automobiles and motorcycles with a liquid-cooled internal combustion engine, a radiator is connected to channels running through the engine and cylinder head, through which a liquid (coolant) is pumped. This liquid may be water (in climates where water is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later t ...

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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-wheeler
A three-wheeler is a vehicle with three wheels. Some are motorized tricycles, which may be legally classed as motorcycles, while others are tricycles without a motor, some of which are human-powered vehicles and animal-powered vehicles. Overview Many three-wheelers which exist in the form of motorcycle-based machines are often called trikes and often have the front single wheel and mechanics similar to that of a motorcycle and the rear axle similar to that of a car. Often such vehicles are owner-constructed using a portion of a rear-engine, rear-drive Volkswagen Beetle in combination with a motorcycle front end. Other trikes include that are specially constructed for off-road use. Three-wheelers can have either one wheel at the back and two at the front (2F1R), (for example: Morgan Motor Company) or one wheel at the front and two at the back (1F2R) (such as the Reliant Robin). Due to better safety when braking, an increasingly popular form is the front-steering "tadpol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honda CR250R
The Honda CR250R was a Honda racing dirt 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' .... The prototype was built in 1971, but it was not until late 1972 that production of the 1973 model "out of the box racers" began sale to the general public. The CR250 was produced for nearly 37 years, 2007 being the final year of production. In 1997, Honda produced an industry first, an aluminum chassis for a motocross motorcycle. These 'first gen' frames were thick, rigid, and were a big change from the previous steel frames, where flexibility had been seen as a problem in the early years. The 1997-8 engines were equipped with a new stator, which supplied DC voltage for the new Keihin carburetor with an electronic 'Power Jet' system, in efforts to control lean mixture preignition.

Consumer Product Safety Commission
The United States Consumer Product Safety Commission (USCPSC, CPSC, or commission) is an independent agency of the United States government. The CPSC seeks to promote the safety of consumer products by addressing “unreasonable risks” of injury (through coordinating recalls, evaluating products that are the subject of consumer complaints or industry reports, etc.); developing uniform safety standards (some mandatory, some through a voluntary standards process); and conducting research into product-related illness and injury. In part due to its small size, the CPSC attempts to coordinate with outside parties—including companies and consumer advocates—to leverage resources and expertise to achieve outcomes that advance consumer safety. The agency was created in 1972 through the Consumer Product Safety Act. The agency reports to Congress and the President; it is not part of any other department or agency in the federal government. The CPSC has five commissioners, who are nom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
