TT Circuit Assen

Assen is the longest serving venue on the calendar, having held a round every year since 1949 with the sole exception of 2020. The circuit was purpose built for the Dutch TT in 1955, with previous events having been held on public roads. The track is narrow, with rapid changes in direction, and is fully surrounded by grass banks and grandstands, providing excellent viewing for the hundreds of thousands of fanatical spectators who are drawn to the most prestigious event in Dutch motorsport every year. A huge favourite with riders, Assen is well known for its festive and extravagant atmosphere. In 1999 the circuit was modified with a new grandstand, control tower, press centre and renovated boxes. Modifications to the Assen circuit over the winter of 2005/6 saw the length of the championship’s longest serving track cut from over 6km down to 4.555km/2.83miles.
