TT Assen
TT Circuit Assen
Assen is the only venue to have held a round of the Motorcycle World Championship every year since its creation in 1949. The circuit was purpose built for the Dutch TT in 1955, with previous events having been held on public roads. Modifications to the Assen circuit over the winter of 2005/6 saw the length cut from over 6km down to 4.555km/2.83miles.
