SUPER MOTOR BIKE

Super motor bikes .Fast, light, sleek motorcycles designed to give maximum performance for racing or spirited road riding while conforming to FIM rules. They are distinguishable by their racing style fairings and the rider's tipped-forward seating position. They are also called "race replicas" because of their connection to the racing category for production motorcycles known as SUPER BIKES and earlier similar race series (the term arose in the 1980s). The power to weight ratio of the 900 cc+ models typically matches or exceeds one bhp of power for every one kg of mass.
Racing bikes: Motorcycles designed for circuit or road racing, including mass-production motorcycles modified for MOTOR RACING
Street customs: Highly customised motorcycles with wild paint jobs also built for show, but constructed from a sport bike frame instead of a cruiser-style frame.
