World motocross will span 18 rounds in 2014.

Youthstream has announced minimal changes to the 2014 MXGP World Championship calendar.

The penultimate round of the series, the Grand Prix of State of Goias, was originally scheduled for 31 August, but has now been bumped back to 7 September.

As a result, the final round of the season in Leon, Mexico, will be moved back a weekend from 7 September to 14 September.

Three dates still remain as TBA locations, with Youthstream anticipated to announce those rounds in the coming weeks.

Australia will have three riders on the MXGP grid in 2014 including Dean Ferris (Dixon Yamaha) and Todd Waters (Red Bull ICE1 Racing Husqvarna) in MX1, plus Luke Styke (Yamaha) in MX2.
