Sentul International Circuit is a permanent motor racing circuit located in Babakan Madang, Bogor. Away from the Toll Gate of Jakarta towards Bogor, Indonesia.[1] Its pit facilities got easy access from the Jagorawi Toll Road. The course (run clockwise) is actually a truncated version of the original design. The current circuit is shortened 40% in length compared to the original design and now predominantly used for motorcycle racing and the Asian F3 series. Sentul is a relatively simple, smooth, broad track with large runoff areas, enabling non-bumpy and smooth driving at racing speeds. Sentul has a 900m long main straight enable the speed of up to 300 km/h before slowing down for the right-hand Turn 1. The only truly high-speed corner at Sentul is the Turn 2. The fastest driver on four-wheel machine can do 220 km/h and the fastest rider can do 190 km/h on two-wheel machines. They can take the Turn 2 as a complex 'S' bend when they get out from the tighter Turn 1 at around 140 km/h. The wide corners allow good passing with various racing lines. Sentul is located in Bogor Regency. It is a hilly area and a bit cooler than the tropical city of Jakarta. However, the track can still get extremely hot under direct sunlight. It is also humid and wet as well. Such characters cause distress to European tuners, riders and drivers who are accustomed to cooler climates.
