There were massive highs for Team Australia and bitter disappointments for Team New Zealand at the 77th edition of the Motocross of Nations ( MXoN ) on the Matterley Basin circuit , near Winchester , in southern England . The three-man team from Australia celebrated winning their first Chamberlain Trophy on Sunday , winning the MXoN outright ahead of the three-rider squads from the United States , The Netherlands , Spain and France . Meanwhile , with 36 nations represented at this year ’ s event and spaces only for 20 teams in the MXoN main event , a “ whittling down ” qualification process was required and , like a penalty shootout in football , this can be cruel at the best of times . Suffice to say , luck didn ’ t favour the Kiwis this time around .
