As i know there are some level of sportbikes:
Entry-Level
This type of motorbikes is the basic bikes for novice,it is easy and fun to ride and it is similar to big bikes.The engine capacity is around 125CC-250CC,some of it are racing specs that made as the same bikes that used in Moto GP.The Price is affordable and the weight is not as heavy as supersport bikes.It is available both in 2-Strokes and 4-Strokes.The example of this motor bikes are:Cagiva Mitto,Aprilia RS125,Aprilia RS50,Honda CBR 150R,Kawasaki Ninja 250 RR,and Yamaha YZF-R125
Super Sport Bikes
This genre of motorbikes is the advanced level bikes for riders who have already mastered the entry-level bikes.
Super bikes are large displacement super sport bikes. They have characteristics similar to the smaller super sport bikes which are mainly focused on race track performance, but are powered by larger engines that are usually sized around 800 cc (48.8 cu in) to 1,200 cc (73.2 cu in). A typical super bike will carry a wet weight between 400 lb (181 kg) to 480 lb (218 kg) and can produce 180 bhp (134 kW). Super bikes with a displacement very close to 1,000 cc (61.0 cu in) are sometimes referred to as litre bikes as the engine displaces approximately one litre. Motorcycles in this class are usually eligible to participate in Superbike racing. Examples include the Ducati 1098R, Suzuki GSX-R 1000, Kawasaki ZX-10R, Honda CBR1000RR, Buell 1125R, and Yamaha YZF-R1.
Hyper sport
Hyper sport bikes are very large displacement sport bikes with a strong emphasis on top speed and acceleration. They typically are powered by motors displacing 1,100 cc (67.1 cu in) to 1,400 cc (85.4 cu in). Hyper sport bikes are bigger and heavier than super bikes with wet weights generally being close to 500 lb (227 kg). The increased weight compromises race track capabilities in favor of stability at very high speeds that can exceed 180 mph (290 km/h). This compromise also allows manufacturers to design much more comfortable rider ergonomics.
Examples include the Honda CBR1100XX, Kawasaki Ninja ZX-14, and Suzuki Hayabusa.
Sport Touring
Sport touring bikes are designed with a longer distance riding emphasis. They typically feature more creature comforts than that of the average sport bike. Sport touring bikes are typically heavier, less powerful, and less performance oriented than super sport bikes, but have the added capabilities of storage, more comfortable rider ergonomics, and better practicality. Depending on the amount of emphasis on these touring capabilities, sport touring bikes can range from super sport bikes with more comfortable rider ergonomics to full-featured touring motorcycles with sport bike-like capabilities and features.
Examples include the Honda VFR800, Triumph Sprint ST, and Yamaha FJR1300.
