Sport bikes are street-legal motorcycles that are replicas of racing bikes. These bikes are built for speed and performance but are tuned down to accommodate street driving. There is truly very little difference between the professional racing bikes and sport bikes available to the general public. While many think of these as being the most dangerous of motorcycles, this is not true. The sport bike probably offers the best acceleration, braking, and cornering ability of any bike. These attributes, when used correctly, can be an advantage in staying safe on the road.
Sport bikes usually have a more streamlined, aerodynamic design compared to other motorcycle types. The footpegs are located further back than conventional motorcycles, which enables the rider to position himself in a lower, more aerodynamic stance. Another typical characteristic is the ability to travel at extreme speeds with explosive acceleration. A typical sport bike can accelerate to 100 km/h (62 mph) about or under 3 seconds. Some sports bikes can top out at approximately 260 km/h (160 mph). Superbikes, which are another type of sports bike, can have top speeds well above 200 mph but recently have been limited through the use of a rev limiter to the speed of around 185 mph (300 km/h) in accordance to a Gentlemen's agreement. Honda, Kawasaki, Suzuki, Yamaha, Ducati, Aprilia, and Buell are the main manufacturers of sport bikes. In 1999 Suzuki produced a GSX-1300R Hayabusa capable of reaching 80 mph in first gear, and 220 mph (352 km/h)off the production line. The Kawasaki ZX-10R, for example, is a 1000 cc sportbike capable of exceeding 100 mph in first gear, as well as a top speed at or above 186 mph without any modifications. These bikes can do a quarter mile at or under 10 sec. The 2006 Kawasaki Ninja ZX-14 (stock) can reach 100 km/h under 2.5 seconds and does a quarter mile in 9 second flat.
