TheJarno Saarinen Imatra Circuit is amotorsportstreet circuit inImatra,Finland. Since 2022 the circuit name was additionally givenJarno Saarinen's name as a memorial homage to the 50th Anniversary of his World Championship.[1] The circuit has existed in two versions, and has been exclusively used for the "Imatranajo [fi]"motorcycleroad race. From 1962 to 1978 a 6.030 km (3.747 mi) clockwise street circuit in the east of the town of Imatra was used. The circuit ran along theVuoksi river and a railway line that had to be crossed. From 1979 to 1986 a shorter circuit was used. This was only 4.950 km (3.076 mi) long and consisted mostly of the western part of the original circuit.
From the 1964 season until the 1982 season theGrand Prix of Finland was run 19 times in Imatra. From the 1983 season the "Imatranajo" lost its World Championship status due to the dangerous nature of the circuit and the death of sidecar driverJock Taylor in 1982.[2]
The last road race on the Imatra Circuit for many years was held in 1986 when a six-year-old boy died after falling under a running wheel, but classic races still took place. Road racing returned to Imatra in August 2016[3] with a round of theInternational Road Racing Championship, and another round was held in 2017.[4] In the "Imatranajo" on June 15, 2019, a fatal crash occurred when a Swiss rider Mathias Gnägi with a Superbike dropped off the track in the rain and was killed.Another fatal accident occurred on the 2nd of July 2023, when former IIRC Supersport ChampionJoey den Besten from the Netherlands, came off the track in a IRRC Superbike Round in the wet on a warm-up lap and struck a lighting pole.[5]
