Cagiva Roadster
The Roadster 521 is a 125cc motorcycle made by the Italian motorcycle firm, Cagiva in the 1990s. One of the fastest accelerating 125cc motorcycles of its time, the Roadster 521 is known to have a top speed of 80 mph restricted and an estimated 100 mph+ un-restricted. Achieving approximately 70 miles per gallon, it is relatively economical for a 2-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 t ... motorcycle.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cagiva
Cagiva is an Italian motorcycle manufacturer. It was founded in 1950 by Giovanni Castiglioni in Varese, originally producing small metal components. Giovanni's sons, Claudio and Gianfranco Castiglioni, went into the motorcycle industry in 1978. The name is a portmanteau derived from the founder's name 'Giovanni Castiglioni' and the founding location, i.e. ''CAstiglioni GIovanni VArese''. In its history, Cagiva won races in Dakar and Motocross competitions, as well as in Grand Prix motorcycle racing. History In 1978, Cagiva entered the motorcycle business with two racing motorcycles ridden by Gianfranco Bonera and Marco Lucchinelli. In the same year it bought a factory in Varese's frazione of Schiranna from Aermacchi/AMF-Harley-Davidson and went into motorcycle production. By 1979 the company reached an annual production of 40,000 motorbikes, with eight models powered by two-stroke engines ranging from 125 cc to 350 cc. Many of the Harley-Davidson models were contin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-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 two-st ...

Two-stroke Motorcycles
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.

Single-cylinder Motorcycles
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] |
