The Dutch TT will move from its traditional Saturday slot to become a Sunday MotoGP race next year, organisers announced on Thursday.
The Assen race has usually been held on the last Saturday of June, being the only race in the world championship calendar not taking place on Sunday.
However, in order to boost attendance, the Assen board has decided to move the race from next year.
"In the current Dutch leisure pattern a top sporting event on a Sunday is more attractive than on a Saturday," said a statement by Assen.
"On Sundays there is also more media exposure for these top sporting events, which is something the TT Assen will definitely benefit from.
"This has also proven to increase visitor numbers. By moving the training days to Friday and Saturday, the TT Assen becomes more attractive for a multi-day visit and therefore also for the purchase of all-in tickets.
"Moving the TT to Sunday is a better fit with the pattern of other events in motor and motorcycle racing and with the spirit of the times. Nearly all top sporting events around the world take place on a Sunday.
"They will be maintaining the tradition of the last weekend in June, so the move from the Saturday to the Sunday could be seen as an old tradition with a modern twist."
