Motorcycle Tyre
A motorcycle tyre (spelt tire in American English) is the outer part of motorcycle wheel, attached to the rim (wheel), rim, providing traction (engineering), traction, resisting wear, absorbing surface irregularities, and allowing the motorcycle to turn via countersteering. The two tyres' contact patches are the motorcycle's connection to the ground, and so are fundamental to the motorcycle's suspension (motorcycle), suspension behaviour, and critically affect Motorcycle safety, safety, Brake, braking, fuel economy in automobiles, fuel economy, Roadway noise, noise, and rider comfort. History The history of motorcycle tyres is a clear progression of steady improvement in grip, allowing better acceleration, braking, and turning, along with improved comfort, safety, durability, and reliability. This progression has generally meant a steady increase in tyre width, so much so that Kevin Cameron (journalist), Kevin Cameron noted the assumption among riders that "bigger must be better in ...

Hildebrand & Wolfmüller
The Hildebrand & Wolfmüller was the world's first production motorcycle. Heinrich and Wilhelm Hildebrand were steam-engine engineers before they teamed up with Alois Wolfmüller to produce their internal combustion ''Motorrad'' in Munich in 1894. Mechanical details The Hildebrand & Wolfmüller patent of 20 January 1894, No. 78553 describes a Straight-twin engine, two-cylinder, four-stroke engine, with a bore and stroke of . It produced @ 240 rpm propelling a weight of up to a maximum speed of .The fuel-air mixture from the Surface carburetor, surface carburettor was regulated by a valve operated by controls on the handlebar. The engine, which was positioned flat in the frame, used hot tube ignition with the tube heater in front of the cylinder heads. The tube heater was ventilated by the lower downtubes while the upper downtubes held lubricating oil. Some design details were carried over from a steam-powered prototype made by the Hildebrand brothers in 1889, including th ...

Center Of Mass
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weight function, weighted relative position (vector), position of the distributed mass sums to zero. For a rigid body containing its center of mass, this is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the Phys ... [...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] |
Superbike 21 Elena Myers Leaning Road America 2015
A sports motorcycle, sports bike, or sport bike is a motorcycle designed and optimized for speed, acceleration, braking, and cornering on asphalt concrete race tracks and roads. They are mainly designed for performance at the expense of comfort, fuel economy, safety, noise reduction and storage in comparison with other motorcycles. Sport bikes can be and are typically equipped with fairings and a windscreen to deflect wind from the rider to improve aerodynamics. Soichiro Honda wrote in the owner's manual of the 1959 Honda CB92 Benly Super Sport that, "Primarily, essentials of the motorcycle consists in the speed and the thrill," while ''Cycle World''s Kevin Cameron says that, "A sportbike is a motorcycle whose enjoyment consists mainly from its ability to perform on all types of paved highway – its cornering ability, its handling, its thrilling acceleration and braking power, even (dare I say it?) its speed." Motorcycles are versatile and may be put to many uses as the ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Rubber
A synthetic rubber is an artificial elastomer. They are polymers synthesized from petroleum byproducts. About of rubber is produced annually in the United States, and of that amount two thirds are synthetic. Synthetic rubber, just like natural rubber, has many uses in the automotive industry for tires, door and window profiles, seals such as O-rings and gaskets, hoses, belts, matting, and flooring. They offer a different range of physical and chemical properties which can improve the reliability of a given product or application. Synthetic rubbers are superior to natural rubbers in two major respects: thermal stability, and resistance to oils and related compounds. They are more resistant to oxidizing agents, such as oxygen and ozone which can reduce the life of products like tires. History The expanded use of bicycles, and particularly their pneumatic tires, starting in the 1890s, created increased demand for rubber. In 1909, a team headed by Fritz Hofmann, working at ...

Sidecar
A sidecar is a one-wheeled device attached to the side of a motorcycle, Scooter (motorcycle), scooter, or bicycle, making the whole a three-wheeled vehicle. The combination of a motorcycle with a sidecar is sometimes called a ''rig'', ''outfit'', or ''hack''. History Jean Bertoux, a French army officer, secured a prize offered by a French newspaper in 1893 for the best method of carrying a passenger on a bicycle. The sidecar wheel was mounted on the same lateral plane as the bicycle's rear and was supported by a triangulation of tubes from the bicycle. A sprung seat with back rest was mounted above the cross-member and a footboard hung below. A sidecar appeared in a cartoon by George Moore in the January 7, 1903, issue of the British newspaper ''Motor Cycling (magazine), Motor Cycling''. Three weeks later, a provisional patent was granted to Mr. W. J. Graham of Graham Brothers, Enfield, Middlesex. He partnered with Jonathan A. Kahn to begin production. One of Britain's oldest ...

Scooter (motorcycle)
A scooter (motor scooter) is a motorcycle with an underbone or step-through frame, a seat, a transmission that shifts without the operator having to operate a clutch lever, a platform for their feet, and with a method of operation that emphasizes comfort and fuel economy in automobiles, fuel economy. Elements of scooter design were present in some of the earliest motorcycles, and motor scooters have been made since at least 1914. More recently, scooters have evolved to include scooters exceeding 250cc classified as Maxi-scooters. The global popularity of motor scooters dates from the post-World War II introductions of the Vespa and Lambretta models in Italy. These scooters were intended to provide economical personal transportation (engines from ). The original layout is still widely used in this application. Scooter (motorcycle)#Maxi-scooter, Maxi-scooters, with larger engines from have been developed for Western markets. Scooters are popular for personal transportation par ...

Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed) an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole e ...

Tubeless Tyre
A tubeless tire ( also spelled as tubeless tyre in Commonwealth English) is a pneumatic tire that does not require a separate inner tube. Unlike pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire that are forced by air pressure into a flange on the metal rim of the wheel, sealing the tire to the rim. History Many patents had been filed covering tubeless tires. ''Killen Tire'' applied for a patent in 1928 and was granted in the UK in 1930. The Wingfoot Corporation, a subsidiary of Goodyear Tire were granted a patent in South Africa in 1944. Due to technical problems, most of these designs saw only limited production or were abandoned. Frank Herzegh working for BF Goodrich applied for a patent in 1946 and eventually received in 1952 in the United States. By 1955 tubeless tires became standard equipment on new cars. BF Goodrich had to defend their patent in court several times, due to the similarit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alloy Wheel
In the automotive industry, alloy wheels are wheels that are made from an alloy of aluminium or magnesium. Alloys are mixtures of a metal and other elements. They generally provide greater strength over pure metals, which are usually much softer and more ductile. Alloys of aluminium or magnesium are typically lighter for the same strength, provide better heat conduction, and often produce improved cosmetic appearance over steel wheels. Although steel, the most common material used in wheel production, is an alloy of iron and carbon, the term "alloy wheel" is usually reserved for wheels made from nonferrous alloys. The earliest light-alloy wheels were made of magnesium alloys. Although they lost favor on common vehicles, they remained popular through the 1960s, albeit in very limited numbers. In the mid-to-late 1960s, aluminium-casting refinements allowed the manufacture of safer wheels that were not as brittle. Until this time, most aluminium wheels suffered from low ductility ...
