Motocross of Nations (MXon) is both the ultimate test and honour for the elite group of riders chosen to take part.

With the world and domestic championships signed and sealed, the slate is wiped clean as riders return to their roots to pull on jerseys emblazoned with their national colours.

The dynamic is different across the board. In some cases, ferocious rivalries must be put on ice to work towards the common goal. In others, mates who compete thousands of kilometres apart are reunited for a few days.

41 teams and 133 riders have the honour of representing their countries as the event kicks off in Teutschenthal, Germany this week, with in excess of 70,000 fans expected to make their way to see the spectacle.

2013 sees Germany carry the defending champions mantle into the event after spectacularly upstaging the United States who were riding a seven-year win streak before the sands of Lommel in Belgium swallowed their chances.

Despite that minor blip, the US is still far and away the most dominant nation of the modern era, having won 11 of the last 20 events since Australia hosted the 1992 MxON in Manjimup.

41 nations will be vying for their place at the start gates at this week’s MxON event in Germany.
