About Thailand Circuit
Overview
Thailand Circuit, officially the Nakhonchaisri Motor Sport Complex, is a permanent racing venue in Wat Lamut subdistrict, Nakhon Chai Si district, Nakhon Pathom province, on the road from Nakhon Chai Si to Don Tum. It lies about 50 kilometres west of Bangkok, roughly an hour's drive from the city centre, which makes it the closest permanent road course to the capital. The complex was established in 1989 to promote motorsport in Thailand and is run by Nakhonchaisri Motor Sport Complex Co., Ltd. under its founder Thongchai Wongsawan. Besides the asphalt road course, the site has a motocross track and areas used for supercross, off-road riding, karting, drifting and time attack.
Technical Specifications and Track Features
The road course is 2.5 kilometres long and 12 to 15 metres wide, and it is homologated to FIM standards for motorcycle road racing. Published corner counts differ: one description gives fifteen turns, nine right-handers and six left-handers, while a 2015 description counts thirteen turns including two chicanes. The track is used by both motorcycles and cars, and its uses include racing, club meetings, track days, driver training and safety-driving courses, media test drives and product launches.
Facilities and Specialized Areas
Thirty pit garages, a timing tower and a small spectator area are lined up along the main straight. The FIM-approved motocross track next to the road course hosts the annual Thai Motocross Grand Prix, a three-day international event run under the national motorcycle federation, and it hosted the Thai round of the MXGP world championship in 2015. The circuit is the home of the Road Racing Motorsport Club, which works with the national car and motorcycle federations, and manufacturers such as Yamaha and BMW have used it for marketing and owners' club activities. The racing season runs from March to November, with the R2M Thailand SuperBikes championship as the main series, along with time attack rounds, club endurance races and grassroots events.
History
The site began as a motocross track in 1980. A road course of 1.3 kilometres was built first and extended in 1989 to its present length of 2.5 kilometres, the year the Nakhonchaisri Motor Sport Complex was established. Between 1996 and 2001 the circuit was a regular venue of the Asia Road Racing Championship, and it later hosted the Asia Cup of Road Racing. In 2008, marking thirty years of the founder's FM:T Thailand Road Racing and Top Gear Group, the facilities were renovated to serve motorcycle and car manufacturers and the automotive industry alongside racing.
