Aprilia RS50
The Aprilia RS50 is a sport moped made by Aprilia. The model made until 2005 was powered by a single cylinder two-stroke aluminium cylinder block, liquid cooled Motori-Minarelli AM6 engine. The new model, made since 2006, uses a single cylinder two-stroke aluminium cylinder block, liquid cooled engine made by Derbi, the D50B0. The bike is popular in countries that have restrictions on motorcycle engine size at specific ages. In restricted form the RS50 is capable of speeds of , as per the laws in many European countries for those aged 16. In derestricted form, the 1997 model was tested at a speed of . This and other similar machines such as the Derbi GPR 50 and Yamaha TZR50 have also been popular choices as a more adult-sized option for MiniGP racing, which is otherwise more commonly participated in by riders of smaller bikes such as the Honda NSR50.

Aprilia
Aprilia is an Italian motorcycle manufacturer founded immediately after World War II in Noale, Italy, by Alberto Beggio. The company started as a manufacturer of bicycles and moved on to manufacture scooters and small-capacity motorcycles. In more recent times Aprilia has produced large sportbikes such as the 1,000 cc V-twin RSV Mille and the V4 RSV4. Aprilia has supported a strong motorsport competition program beginning with motocross racing and then a world championship-winning road racing program. The company was acquired by Piaggio in 2004. History Aprilia was founded after the Second World War by Cavaliere Alberto Beggio as a bicycle production factory at Noale, Italy, in the province of Venice. Alberto’s son, Ivano Beggio, took over the helm of the company in 1968 and constructed a 50 cc "motorcycle". The first production Aprilia mopeds were named Colibrì, Daniela and Packi. Aprilia later produced a motocross bike in 1970 called the Scarabeo. Produced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Types Of Motorcycles
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 definitions of a mot ...

Sport Moped
A sport moped is a moped that resembles a sport bike and often performs better than standard mopeds. They were created to circumvent UK legislation, called the "Sixteeners Laws", aimed at taking young motorcycle riders off the road. The new laws, introduced in 1971 by Conservative Party Minister for Transport John Peyton, forbade 16-year-olds from riding motorcycles of capacity, thus limiting them to ''50 cc'' machines until they turned 17. Description The law resulted in motorcycle manufacturers developing a new class of high-performance mopeds in the 1970s, termed "sports mopeds" or, colloquially, "sixteener specials," due to their marketing being aimed at 16-year-olds, a move which was widely criticized at the time. If the speed limiter is removed, a four-stroke engine sport-moped can exceed , while those with two-stroke engines can reach speeds of over . To achieve higher performance, motorcyclists frequently modify the engines, such as installing a big bore kit which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single Cylinder
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] |
Two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a Thermodynamic power cycle, 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 (automotive), 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 Scotland, Scottish engineer Dugald Clerk, who pa ...

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 unlik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derbi
Derbi is a manufacturer of motorcycles, scooters, mopeds and recreational all-terrain vehicles produced by Nacional Motor S.A.U., a Spanish subsidiary of Piaggio & Co. SpA. History Derbi's origins began with a little bicycle workshop in the village of Mollet near Barcelona, founded in 1922 by Simeó Rabasa i Singla (1901–1988). The focus remained the repair and hire of bicycles until May 1944 when Rabasa formed a limited liability company named Bicycletas Rabasa with the aim of moving into manufacturing bicycles. The venture proved very successful and in 1946, supported by its profits, work began on a motorised version. More moped than motorcycle, this first model, the 48cc SRS included plunger rear suspension, and a motorcycle type gas tank and exhaust system. The SRS proved so successful it prompted a change in the company's direction, and on November 7, 1950, the company changed its name to the Nacional Motor SA. Just prior to this, at that summer's Barcelona Trade Fai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Jerusalem Post
''The Jerusalem Post'' is a broadsheet newspaper based in Jerusalem, founded in 1932 during the British Mandate of Palestine by Gershon Agron as ''The Palestine Post''. In 1950, it changed its name to ''The Jerusalem Post''. In 2004, the paper was bought by Mirkaei Tikshoret, a diversified Israeli media firm controlled by investor Eli Azur. In April 2014, Azur acquired the newspaper ''Maariv''. The newspaper is published in English and previously also printed a French edition. Originally a left-wing newspaper, it underwent a noticeable shift to the political right in the late 1980s. From 2004 editor David Horovitz moved the paper to the center, and his successor in 2011, Steve Linde, pledged to provide balanced coverage of the news along with views from across the political spectrum. In April 2016, Linde stepped down as editor-in-chief and was replaced by Yaakov Katz, a former military reporter for the paper who previously served as an adviser to former Prime Minister Naftali ...
