Sport bikes have high foot pegs that position the legs closer to the body to improve ground clearance when cornering, and a long reach to the hand controls, which positions the body and center of gravity forward, above the fuel tank. The rider leans forward into the wind, the force of which can comfortably support the rider's weight at speeds near 100 mph (160 km/h), but at lower speeds leaves too
much weight on the arms and wrists, causing fatigue. Street fighters are derived from sport bikes, originally being customized sport bikes with the fairings removed and higher handlebars replacing the low clip-on handlebars.Since the 1990s, factory street fighters have been produced.] As with naked bike and muscle bike (below), the name street fighter is used to help clarify the middle ground occupied by designs that blend elements of both sport bikes and standards.
