Beginning

The first Assen track was firstly used for the 1925 Dutch TT race, held on country side roads through the villages of Borger, Schoonloo and Grolloo, and organized by the Motorclub Assen en Omstreken. The brick-paved track had a length of 28.4 km. The winner was Piet van Wijngaarden on a 500 cc Norton with an average speed of 91.4 km/h.

The years afterwards the Dutch TT was held on a road circuit through de Haar, Barteldbocht (near Assen), Oude Tol, Hooghalen, Laaghalen and Laaghalerveen.

In 1951 the Italian Umberto Masetti drove the fastest round on his 500 cc Gilera with an average speed of 161.4 km/h. In 1954 the Britain Geoff Duke reached 169.7 km/h. Until 1955 this old circuit has been used., after which the new circuit came. This circuit is nearly on the same spot as the current circuit.

Current racetrack

The current Assen race track was built in 1955, and initially had a length of 7,705 meters. The current track has a length of 4,555 meters. The longest straight is 970 meters. The curves in Assen were traditionally banked and the surface is extremely grippy, so the riders were able to drive much faster on the course than other circuits. Today these sloped or curved bends have been modified due to safety issues.

Innovation

On July 6 2004 the organization announced plans for an amusements park on the northwards of the track. In 2006 the northern loop was removed and the length was shortened to 4,555 m. The new centre is scheduled to be visited by 300,000 people. The total investment is circa € 85 million.

Trivia

It is the only venue still held at the same location since beginning of the series in 1949.
Dutch TT is always held on last Saturday of June.
It is the only roadracing circuit in the series specifically designed for motorcycle racing.
The track layout makes it a very technical, twisty circuit with little room for error, although track alterations carried out over the years paradoxically make it a 'safe' circuit.
The curves are banked and the surface is extremely grippy, even in wet conditions.
The track is the only one that also plays host to the World Superbike championship and a World Endurance Race.
