Sportbikes
A sport bike (sports motorcycle, or sports 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, 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 rider sees fit. In the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Akrapovič Exhaust Closeup
Akrapovič d.d. () is a Slovenian manufacturer of exhaust systems that began in 1990 in the motorcycle market, and expanded into automobile exhausts in 2010. A global exhaust supplier in motorcycle sport, Akrapovič exhausts are used on motorcycles in Moto GP, superbike, supersport, supermoto, motocross, enduro and rally raid. , Akrapovič systems have been used in a total of 38 world championships, all across motorsport. History Igor Akrapovič began motorcycle racing in 1977 in 250 GP two-strokes, then 1000 cc four-strokes in F1 Open Class, and then in Superbike class by the end of his racing in 1988-1989. He founded a motorcycle tuning shop, Skorpion, with a staff of six, where they made their own exhausts because higher quality Western aftermarket exhausts were too expensive, and those made in the Eastern Bloc were of inadequate quality. Akrapovič says he was motivated by the poor quality of aftermarket exhausts available to the public compared to those used by profe ...

Streetfighter
A streetfighter, muscle bike, or super naked is a motorcycle of high displacement and horsepower. It is typically a super bike with the fairings and windscreen removed. Beyond simply removing fairings, specific changes that exemplify the streetfighter look are a pair of large, round headlights, tall, upright handlebars such as those on a motocross bike, and short, loud, lightweight mufflers, and changes in the sprockets to increase torque and acceleration at lower speeds. ''Streetfighters'' is also the name of a UK motorcycle magazine. Later streetfighters used custom-built frames intended to overcome the weakness of the tubular steel frames of the early 4-cylinder superbikes of the 1970s and 1980s. Many of these frames turned out to be "beautifully crafted pieces of metallurgical art," perhaps only unintentionally. Many were also originally racing machines. Made popular by European riders, this type of custom motorcycle gained worldwide popularity, and motorcycle manufacturer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspension (motorcycle)
A motorcycle's 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 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 Tamburini is a complex front swingarm alternat ...

Motorcycle Brakes
Motorcycle braking systems have varied throughout time, as motorcycles evolved from bicycles with an engine attached, to the prototype motorcycles seen racing in MotoGP. Most systems work by converting kinetic energy into thermal energy (heat) by friction. On motorcycles, approximately 70% of the braking effort is performed by the front brake. This however can vary for individual motorcycles; longer-wheelbase types having more weight biased rearward, such as cruisers and tourers, can have a`greater effort applied by the rear brake. In contrast, sports bikes with a shorter wheelbase and more vertical fork geometry can tolerate higher front braking loads. For these reasons, motorcycles tend to have a vastly more powerful front brake compared to the rear. History Early motorcycles which were essentially a bicycle with a motor attached and did not have any braking system beyond slowing the motorcycle down and putting a foot out. One of the first motorcycles to have any sort of braki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Kawasaki At Champion's Ride Day - Lakeside (17)
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while red ...

Naked Bike
The six main types of motorcycles are generally recognized as ''standard'', ''cruiser'', ''touring'', ''sports'', ''off-road'', and ''dual-purpose''. ''Sport touring'' is sometimes recognized as a seventh category or integrated with the ''touring'' category. Although there are many names and systems for classifying types of motorcycles based on their characteristics and usage, there are generally six categories recognized by most motorcycle manufacturers and organizations. Strong distinctions are usually made between the six main types of motorcycles and other motorcycles. Scooter, moped, underbone, miniature, pocket, electric, and three-wheeled motorcycles are generally excluded from the main categories but other classification schemes may include these as types of motorcycles. There is no universal system for classifying all types of motorcycles. There are strict classification systems enforced by competitive motorcycle sport sanctioning bodies, or Legal definition of motorcyc ...

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 bike handles. Wheelbase 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 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 when measured from horizontal axis. The steering axis is the axis about which the steeri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerodynamic Drag
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorcycle Tyre
A motorcycle tyre (motorcycle tire in American English) is the outer part of motorcycle wheel, attached to the rim, providing 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 behaviour, and critically affect safety, braking, fuel economy, 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 noted the assumption among riders that "bigger must be better in every way", leading to, "the temptation to overwhelm motorcycles with the biggest tyres the owner can find." While many advances in tyre materials and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disc Brake
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create 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 waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. The components include the disc, master cylinder, and caliper (which contains a cylinder and two brake pads) on both sides of the disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. Other designs were not practical or widely available in cars for another 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
