Honda RS250R
The Honda RS250R was a race motorcycle manufactured by Honda to race in the 250cc class of the Grand Prix motorcycle World Championship. It was conceived as a ''production racer'' for customer teams and privateer riders, while factory-supported teams raced the works bikes RS250RW and NSR250. The RS250R debuted in 1984 as a development prototype, racing in the domestic All Japan Road Race Championship and entering some rounds in the World Championship. It was put on sale for customer teams for the season onwards. The Honda RS250R featured a V-twin 250 cc two-stroke engine with a V-angle of 90 degrees. A new 75 degrees V-twin was introduced in 1993. Between 1984 and 2009 the RS250R has been produced in four different generations, named: ND5 (1984), NF5 (1987), NX5 (1993) and NXA (2001). The bike should not be confused with the RS250RW, which was the name adopted for factory bikes in 1985 and from 2003 to 2009. Between 1986 and 2002 the factory bikes were named NSR250. See ...

Two-stroke Engine
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-s ...

V-twin
A V-twin engine, also called a V2 engine, is a two-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. Although widely associated with motorcycles (installed either transversely or longitudinally), V-twin engines have also been used for industrial engines and in several small cars. The V-twin design dates back to the late 1880s. Origins One of the first V-twin engines was built by Gottlieb Daimler in 1889. It was used as a stationary engine, for boats and in the Daimler Stahlradwagen ("steel-wheeled car"), Daimler's second car. The engine was also manufactured under licence in France by Panhard et Levassor. An early V-twin engined motorcycle was produced in November 1902 by the Princeps AutoCar Company in the United Kingdom. The following year, V-twin motorcycles were produced by Eclipse Motor & Cycle Co in the United Kingdom (the ''XL-ALL'' model), Glenn Curtiss in the United States, and NSU Motorenwerke in Germany. ...

Honda NSR250
The Honda NSR250 and Honda RS250RW were race motorcycles manufactured by Honda Racing Corporation to race in the 250cc class of the Grand Prix motorcycle World Championship. Both names identified the factory specification bikes entrusted to works teams, while customer teams used the ''production racer'' Honda RS250R. The first bike debuted in as Honda RS250RW, then from to the factory bikes were named NSR250. In the RS250RW name was resurrected until the demise of the 250 cc class. The 250 cc class world championship was won 11 times by riders riding the Honda RS250RW and NSR250: Freddie Spencer (1985), Anton Mang (1987), Sito Pons (1988, 1989), Luca Cadalora (1991, 1992), Max Biaggi (1997), Daijiro Kato (2001), Dani Pedrosa (2004, 2005) and Hiroshi Aoyama (2009). Honda also mass-produced a road legal Honda NSR250R.

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] |

Grand Prix Motorcycle Racing
Grand Prix motorcycle racing is the premier class of motorcycle road racing events held on road circuits sanctioned by the Fédération Internationale de Motocyclisme (FIM). Independent motorcycle racing events have been held since the start of the twentieth century and large national events were often given the title Grand Prix. The foundation of the Fédération Internationale de Motocyclisme as the international governing body for motorcycle sport in 1949 provided the opportunity to coordinate rules and regulations in order that selected events could count towards official World Championships. It is the oldest established motorsport world championship. Grand Prix motorcycles are purpose-built racing machines that are unavailable for purchase by the general public and unable to be ridden legally on public roads. This contrasts with the various production-based categories of racing, such as the Superbike World Championship and the Isle of Man TT Races that feature modified ve ...

KTM 250 FRR
The KTM 250 FRR was a racing motorcycle made by KTM, which was used in the 250cc class of Grand Prix motorcycle racing from 2005 until 2008. History The bike was created as a 250cc variant to the already existing KTM 125 FRR that KTM participated with in the 125cc. The plans to create this bike also came when the company had plans to participate with a Factory team in the 250cc class in 2005. The bike was equipped with a two-cylinder engine with the arrangement of the front-facing cylinders. Season progress 2005 The bike and team debuted relatively late in the year with Australian rider Anthony West. On its debut, West shocked many when he scored an impressive second place in a wet British grand prix, fighting for the lead after then-leader Hiroshi Aoyama crashed out with fifteen laps to go. However, the results after were lacklustre and West was not able to score any more podiums for the remainder of the season. Overall, the team scored 30 points, getting a best-place fi ...

Suzuki RGV250
The Suzuki RGV250 was a Suzuki high performance sport bike which had a great number of its features and design cues based on Grand Prix technologies and ideas. It is a race-replica based on Suzuki's GP bikes from 1987 to 1998, the RGV V-2 racer. This motorcycle replaced the RG250 Gamma, which employed an alloy frame with a two-stroke parallel twin engine. The bike produced over 60 bhp in a narrow power band between 8,000 and 11,000 rpm. The dry weight ranged between (1989) to (later models) dry weight. The top speed of a standard RGV250 is around . It has a 0- time of around 3.7 seconds. This motorcycle's engine performance is not very inspiring at engine speeds under 7,000 rpm, due to the two-stroke engine power delivery of a relatively narrow power band. However, once the engine is revved over 8,000 rpm, the power delivery characteristics effectively doubles, as is expected of a two-stroke racing motorcycle. Due to its light weight, engine characteristics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kawasaki KR250
The Kawasaki KR250 was a racing motorcycle built by Kawasaki from 1975 to 1982 for the ''250 cc'' class of Grand Prix motorcycle racing. It was powered by a two-stroke " tandem twin" engine The motorcycle won four world championships, in 1978 and 1979 with Kork Ballington and in 1980 and 1981 with Anton Mang. Kawasaki first started to develop the motorcycles in 1974, under the direction of Nagato Sato, and chose the layout in order to minimise the frontal area of the machine and allow a disc valve engine design. In its first years, it was ridden by Mick Grant and gained little success but in 1977 it won the Dutch TT at the Assen racing circuit. The engine design was also used for a road going motorcycle inspired by the racer. Kawasaki KR350 The KR350 was built by Kawasaki from 1978 to 1982 for the ''350 cc'' class of Grand Prix motorcycle racing. The motorcycle was very similar to the smaller KR250.
