Assen is the only circuit to have held a round of the Motorcycle World Championship every year since its creation in 1949. It 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 surrounded by grass banks and grandstands, providing excellent viewing for the massive number of fans drawn to this prestigious event every year. Modifications to the circuit in 2005/6 saw the length of the championship’s longest serving track cut from over 6 km down to its current lap of 4.5 km.
