Comstar Wheels
The Comstar wheel, sometimes referred to as Com-stars or stylised as ComStar, was a composite material, composite motorcycle wheel that Honda fitted to many of its motorcycles from 1977 to the mid 1980s. Its design allowed it the option of being fitted with Tubeless tire, tubeless tyres and its use on the Honda CX500 was the first time tubeless tyres had been designed for a production motorcycle. Background The Comstar was Honda's replacement for the Spoke#Tension spokes, tension spoked wheel. Whilst spoked wheels offered a degree of flexibility to help absorb road imperfections, they also required periodic maintenance to ensure correct spoke tension and required the fitment of an Tire#inner tube, inner tube. Honda claimed the Comstar design combined the strength of a cast wheel but allowed a predetermined level of radial flex like spoked wheels. Comstar wheels also allowed the fitment of tubeless tyres which, like other alloy wheels, helped to reduce unsprung mass, although not ...

Honda NR500
NR500 was a racing motorcycle developed by Honda HRC in 1979 to compete in Grand Prix motorcycle racing. "NR" stands for "New Racing". Model history The motivation behind the NR500 was company founder Soichiro Honda's desire to compete using four-stroke engine technology since the majority of motorcycles manufactured by Honda used four-stroke engines. When the FIM announced new regulations for the 1968 Grand Prix motorcycle racing season that limited the 500 cc engines to four cylinders, this gave an advantage to teams using two-stroke machinery. Honda decided to withdraw from motorcycle racing to concentrate on its automobile division. In November 1977 Honda announced it would be returning to motorcycle Grand Prix racing using four-stroke technology. Even though two-stroke engines dominated motorcycle Grand Prix racing in the late 1970s, Honda felt compelled to race what they sold and thus competed using a high-technology, four-stroke race bike. Since a conventional four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hesketh Motorcycles
Hesketh Motorcycles is a British motorcycle manufacturer, initially based in Daventry and Easton Neston house, Easton Neston, Northamptonshire, England. The company was formed by Alexander Fermor-Hesketh, 3rd Baron Hesketh, Alexander, 3rd Lord Hesketh, to develop a prototype in 1980. After two variations of his business had rapidly failed, from 1984 onwards the marque was maintained and improved by Broom Engineering based at Turweston Aerodrome, on the Northamptonshire border with Buckinghamshire, England. The most recent incarnation of the marque from 2013 is based in Kingswood, Surrey, Kingswood, Surrey, England. Background The project was inspired by Lord Hesketh, who planned to revive the failing British motorcycle industry and at the time had a background of Hesketh Racing, F1 racing being the last private team to win a Formula One Grand Prix motor racing, Grand Prix, with James Hunt at the wheel. Lord Hesketh wanted to use the skills and facilities built up in that p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Racing
Road racing is a North American term to describe motorsport racing held on a paved road surface. The races can be held on a race track, closed circuit—generally, a purpose-built racing facility—or on a street circuit that uses temporarily closed public roads. The objective is to complete a set number of laps in the least amount of time, or to accumulate the most circuit laps within a set time. Road racing emerged the early 20th century, centered in Western Europe and Great Britain, as motor vehicles became more common. After the Second World War, automobile road races were organized into a series called the Formula One world championship sanctioned by the Fédération Internationale de l'Automobile (FIA); motorcycle road races were organized into the Grand Prix motorcycle racing series and sanctioned by the Fédération Internationale de Motocyclisme (FIM). Road races, originally held almost entirely on public roads, were largely moved to closed-circuit tracks to increase p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium-alloy
An aluminium alloy ( UK/IUPAC) or aluminum alloy ( NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to their low melting points, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.I. J. Polmear, ''Light Alloys'', Ar ...

Extrusion
Extrusion is a process used to create objects of a fixed cross section (geometry), cross-sectional profile by pushing material through a Die (manufacturing), die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only compressive stress, compressive and shear stress, shear stresses. It also creates excellent surface finish and gives considerable freedom of form in the design process. Drawing (manufacturing), Drawing is a similar process, using the tensile strength of the material to pull it through the die. It limits the amount of change that can be performed in one step, so it is limited to simpler shapes, and multiple stages are usually needed. Drawing is the main way to produce wire. Metal Bar stock, bars and tube (fluid conveyance), tubes are also often drawn. Extrusion may be continuous (theoretically producin ...
