Sport Motorcycle
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] |
Racing Motorcycle
The motorcycle sport of racing (also called moto racing and motorbike racing) includes motorcycle road racing and off-road racing, both either on circuits or open courses, and track racing. Other categories include hill climbs, drag racing and land speed record trials. Categories The FIM classifies motorcycle racing in the following four main categories. Each category has several subcategories. Road racing Road racing is a form of motorcycle racing held on paved road surfaces. The races can be held either on a purpose-built closed circuit or on a street circuit utilizing temporarily closed public roads. Traditional road racing Historically, "road racing" meant a course on closed public roads. This was once commonplace but currently only a few such circuits have survived, mostly in Europe. Races take place on public roads which have been temporarily closed to the public by legal orders from the local legislature. Two championships exist, the first is the International ...

Bicycle And Motorcycle Geometry
Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase, steering axis angle, fork offset, and trail. These parameters have a major influence on how a Bicycle and motorcycle dynamics, bike handles. Wheelbase The wheelbase is the ''horizontal'' distance between the centers (or the ground contact points) of the front and rear wheels. Wheelbase is a function of rear frame length, steering axis angle, and fork offset. It is similar to the term wheelbase used for automobiles and trains. Wheelbase has a major influence on the Bicycle and motorcycle dynamics#Stability, longitudinal stability of a bike, along with the height of the center of mass of the combined bike and rider. Short bikes are much more suitable for performing wheelies and stoppies. Steering axis angle The steering axis angle is called ''caster angle'' when measured from vertical axis or ''head angle'' w ...

Aerodynamic Drag
In fluid dynamics, drag, sometimes referred to as fluid resistance, is a force acting opposite to the direction of motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers, two solid surfaces, or between a fluid and a solid surface. Drag forces tend to decrease fluid velocity relative to the solid object in the fluid's path. Unlike other resistive forces, drag force depends on velocity. Drag force is proportional to the relative velocity for low-speed flow and is proportional to the velocity squared for high-speed flow. This distinction between low and high-speed flow is measured by the Reynolds number. Drag is instantaneously related to vorticity dynamics through the Josephson-Anderson relation. Examples Examples of drag include: * Net force, Net Aerodynamic force, aerodynamic or Fluid dynamics, hydrodynamic force: Drag acting opposite to the direction of movement of a solid object such as cars, aircraft, and boat hulls. * Viscou ...

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 ...

Suspension (motorcycle)
A motorcycle's Suspension (vehicle), suspension serves a dual purpose: contributing to the vehicle's handling and braking, and providing safety and comfort by keeping the vehicle's passengers comfortably isolated from road noise, bumps and vibrations. The typical motorcycle has a pair of fork tubes for the front suspension, and a swingarm with one or two shock absorbers for the rear suspension. Front suspension The most common form of front suspension for a modern motorcycle is the telescopic Motorcycle fork, fork. Other fork designs are girder forks, suspended on sprung parallel links (not common since the 1940s) and bottom leading link designs, not common since the 1960s. Some manufacturers (e.g. Greeves) used a version of the swinging arm for front suspension on their motocross designs. A single-sided version of the idea is also used in motor scooters such as the Vespa. The hub-center steering as developed by Ascanio Rodorigo, on a concept associated to Massimo Tamburin ...

Disc Brake
A disc brake is a type of brake that uses the #Calipers, calipers to squeeze pairs of #Brake pads, pads against a disc (sometimes called a [brake] rotor) to create friction. There are two basic types of brake pad friction mechanisms: abrasive friction and adherent friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into heat, which must be dissipated to the environment. Hydraulic brakes, Hydraulically Actuator, actuated disc brakes are the most commonly used mechanical device for slowing motor vehicles. The principles of a disc brake apply to almost any rotating shaft. The components include the disc, master cylinder, and caliper, which contain at least one cylinder and two Brake pad, brake pads on both sides of the rotating disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed bra ...

Motorcycle Frame
A motorcycle frame is a motorcycle's core structure. It supports the engine, provides a location for the steering and motorcycle suspension, rear suspension, and supports the rider and any passenger or luggage. Also attached to the frame are the fuel tank and battery. At the front of the frame is found the steering head tube that holds the Swivel, pivoting Motorcycle fork, front fork, while at the rear there is a hinge, pivot point for the swingarm suspension motion. Some motorcycles include the engine as a load-bearing stressed member; while some other bikes do not use a single frame, but instead have a front and a rear subframe attached to the engine. Materials In the early days, motorcycles were little more than motorised bicycles, and consequently frames were tubular steel. While the use of steel tubing is still common, in modern times other materials, such as titanium, aluminium, magnesium, and carbon-fibre, along with composites of these materials, are now used. As differen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorcycle Engine
A motorcycle engine is an engine that powers a motorcycle. Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankel engine, Wankels and electric motors, have been used. Although some mopeds, such as the VéloSoleX, had friction drive to the front tire, a motorcycle engine normally drives the rear wheel, power being sent to the driven wheel by belt, chain or shaft. Historically, some 2,000 units of the Megola were produced between 1921 and 1925 with front wheel drive, and the modern Rokon (motorcycle manufacturer), Rokon, an All-terrain vehicle, all terrain motorcycle with both wheels driven, has been produced since 1960. Most engines have a gearbox with up to six or even 7 ratios. Reverse gear is occasionally found on heavy Touring motorcycle, tourers, for example the Honda Gold Wing, Honda GL1600, and sidecar motorcycles, such as the IMZ-Ural, Ural. The rider changes gears on most motorcycles using a foot-ped ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube (algebra), cube. As an early prime number in the series of positive integers, the number seven has symbolic associations in religion, mythology, superstition and philosophy. The seven classical planets resulted in seven being the number of days in a week. 7 is often considered lucky in Western culture and is often seen as highly symbolic. Evolution of the Arabic digit For early Brahmi numerals, 7 was written more or less in one stroke as a curve that looks like an uppercase vertically inverted (ᒉ). The western Arab peoples' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear. The eastern Arab peoples developed the digit from a form that looked something like 6 to one that looked like an uppercase V. Both modern Arab forms influenced the European form, a two-stroke form cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
