sports bike

bike are the most common vehicles used in the world. sports bike are good in looking and fast in performance.there are many types of sports bike of different company. pulsar, honda, ducati, yamaha, suzuki are the company who produce different types of sports bikes. sports bke are optimized for speed , acceleration, braking and concerning in paved roads. since 1990 sports bike have become more divese. 

The sport bike classes in common usage

• Lightweight, also called entry level, small or beginner bikes. Some two stroke in this class have dramatically higher performance than the four stroke, being likened to miniature superbikes. Sport bikes with engine displacements of up to about 500 cc (31 cu in) are usually in this class.
• Middleweight, mid-sized, mid-level, or supersport^. Some of the models in this range qualify for racing in the classes, AMA super sport champion ship, brirish super sport champion ship and the super sport world campionship, but many middleweights do not have a significant presence in racing. Displacements of 600–750 cc (37–46 cu in) are typical.
• Superbike, liter-class, or literbike, i.e 1,000 cc (61 cu in). As with supersport, many of the models in this class compete in super bike racing.Open class, hypersport or hyperbike are terms sometimes used in lieu of superbike as a catch-all for everything larger than middleweight. Alternatively, these terms mark a class above the superbikes for the largest displacement sport bikes with the highest top speeds, with weights somewhat greater than the superbike class.

The combination of rider position, location of the engine and other heavy components, and the motorcycles geometry help maintain structural integrity and chassis rigidity, and determine how it will behave under acceleration, braking, and cornering. Correct front-to-rear weight distribution is of particular importance to the handling of sport bikes, and the changing position of the rider's body dynamically changes the handling of the motorcycle. Because of the complexity of modeling all the possible movements of different sized riders, to approach perfect tuning of a motorcycle's weight distribution and suspension is often only possible by having a bike customized or at least adjusted to fit a specific rider. Generally, road racing style sport bikes have shorter wheelbases  than those intended for more comfortable touring, and the current trend in sport bike design is towards shorter wheelbases, giving quicker turning at the expense of a greater tendency for unintentional wheelies and stopies under hard acceleration and braking, respectively.

braking system  combine higher performance brake pads and disc brakes with multi-piston calipers that clamp onto oversized vented rotors. suspension systems are advanced in terms of adjustments and materials for increased stability and durability. Front and rear tires are larger and wider than tires found on other types of motorcycles to allow higher cornering speeds and greater lean angles. fairings may or may not be used on a sport bike; when used, fairings are shaped to reduce aerodynamic drag  as much as possible and provide wind protection for the rider.

Motorcycles are versatile and may be put to many uses as the rider sees fit. In the past there were few if any specialized types of motorcycles, but the number of types and sub-types has proliferated, particularly in the period since the 1950s. The introduction of the honda cb750 in 1969 marked a dramatic increase in the power and speed of practical and affordable sport bikes available to the general public.
