Kyalami is a motor racing circuit, and suburb in Gauteng, South Africa north of Johannesburg. The circuit has been used for Grand Prix and Formula One races and has hosted the South African Grand Prix many times. In recent years, the area surrounding the circuit has developed into a residential and commercial suburb of Johannesburg. The circuit has also played host to five rounds of the World Superbike series from 1998 - 2002. The original, sweeping circuit was in use from 1962 until political sanctions eliminated the Grand Prix after the 1985 race. When the circuit was rebuilt in the early 1990s as part of a commercial development, the pit straight, Crowthorne bend, Barbeque and Jukskei sweep corners were either eliminated or heavily modified, with the result that the circuit became a narrow, twisty ribbon rather than one of the fastest circuits on the calendar. Formula One abandoned the rebuilt circuit in 1993 after just two races (and a bankruptcy on the part of the promoter).
