The Motocross of Nations is now only days away, which means if the riders and teams haven't made the trip to Colorado yet, or haven't at least landed on U.S. shores by now, well then good luck! We paid a visit to the KTM North America headquarters earlier this week to see what they are doing to prepare and found their race shop filled with bikes, but obviously not for Team USA. As you may know, not only is the European-based Red Bull KTM factory squad the most dominant team on the World Motocross tour (they captured the MX1, MX2, and FIM WMX championships this year) they harbor a very internationally diverse stable of riders from Italy (Antonio Cairoli), Portugal (Rui Goncalves), Great Britain (Shaun Simpson), France (Marvin Musquin), The Netherlands (Jeffrey Herlings), and Germany (Max Nagl).

While not all of the main team riders will be competing at the Red Bull Motocross of Nations at Thunder Valley on Saturday and Sunday, most of them will be representing their respective nations. Following the USGP held earlier this year at Glen Helen, the Red Bull KTM factory team decided to simply leave their machinery Stateside since they knew they would be returning in a few months for the MXoN. So this week they simply brought a few extra parts with them and rebuilt the race bikes to prepare for the weekend. Take a look at some of the sweet Austrian equipment.

We know Team USA is strong, but who do you think will pose the biggest challenge to the Americans? France, Italy? Who knows, maybe there is a nation that will surprise everyone. Could Australia's new roster finally land them a decent MXoN finish? And then there is always Team USA II, better known as Puerto Rico. The little island may not be a sovereignty, probably has more people living on the mainland than on the territory itself, and only have one true Puerto Rican on the team, but Kyle Regal and Zach Osborne are no slouches on dirt bikes and could play spoilers by the end of the weekend.

What do you think? Come on peanut gallery, let's see some predictions! Who is faster, Antonio Cairoli or Ryan Dungey? The question will finally be answered in just a few short days.

If you are unable to make it to Denver for the race, you can watch it live on at no cost in low quality, or pay the extra fee for the HD feed.
