Superbike - Motorland Aragon WSBK weekend put back a week

The Spanish round of the 2013 World Superbike season has been delayed by a week in April.

It will now take place on the weekend of April 14.

The updated provisional calendar has kept the weekend of June 23 open, with Brno and Misano still missing from the list ahead of the confirmation of one more race weekend.

Jerez, Laguna Seca and the Buddh International Circuit have been added to an increased 15-meeting schedule, while Miller Motorsports Park has been axed in favour of Laguna Seca.

Motorland Aragon has moved to third in the season - the first races of the European season - while Portimao and Moscow will also be held earlier in the year than before.
