Sport bikes are not pedal bikes; rather they are a class of motorcycle. They are specifically designed with performance uppermost in the development priority list. This means that they are often less comfortable to ride than a cruiser (Harley) style bike, but they handle, accelerate, and brake, better. They’re the type of bike most often seen in professional racing circuits.
Sport bikes come in a variety of classifications, based on engine size. The entry level bikes are designed to let beginners get a feel for this style of motorcycle without giving them more engine than they can handle. Above them are small capacity bikes, these bikes range from 125-400 cc engines. Above them are the super sport or SS bikes with an engine size of around 600 cc.
SS bikes are a step below super bikes, which have an engine range of 800-1200 cc. The sport bikes around 1000 cc are still eligible to participate in superbike racing, above that size is usually disqualified. Finally in the range of 1100-1400 cc there are hyper sport bikes, these bikes are usually tuned in a way that maximizes stability at top speed, rather than handling. That is why there’s a 100 cc overlap between them and super sports.
