Assen is the only venue that has hosted a grand prix event every year since the motorcycle World Championship Grand Prix series started back in 1949 and below are some facts and figures from the previous events at this famous circuit:
- The Dutch TT became part of the world championship series when it was first created in 1949 and Assen is the only circuit to have been part of the series every year since, making this the 68th Dutch TT that has counted towards the world championship classification.
- At all previous Dutch TT events the racing has taken place on Saturday; in 2016 the event will be held on Sunday for the first time.
- The original Assen circuit, that was used up to 1954, measured 16.54 km. This was reduced to 7.7 km in 1955 and then in 1984 further modifications to the circuit reduced the length to 6.1 km. The current layout has been used since 2006, with a few minor adjustments.
- The 500cc race at the 1975 Dutch TT is the only premier-class grand prix race where the first two riders across the line have been credited with the same race time. Barry Sheene and Giacomo Agostini finished so close that the timekeepers of the day, using manual timing accurate to 0.1 sec, were unable to split them.
- Yamaha are the most successful manufacturer at the Dutch TT since the start of the four-stroke MotoGP™ formula, with eight victories. Honda have had five MotoGP™ wins at the Dutch TT and Ducati a single win in 2008.
- The last win by Suzuki at the Dutch TT was in the 500cc race in 1993 with Kevin Schwantz. The best results by Suzuki in the MotoGP™ era at the Dutch TT are fifth place finishes by John Hopkins in 2007 and Chris Vermeulen in 2009.
- Ben Spies’ win at the Dutch TT in 2011 was the last MotoGP™ race won by a rider other than one of the following; Casey Stoner, Valentino Rossi, Dani Pedrosa, Marc Marquez, Jorge Lorenzo.

- Among the current riders, Valentino Rossi has been most successful at Assen with a total of nine victories, seven in MotoGP™ and one each in the 250cc and 125cc classes.
