This one has more mechanic changes than riders, though there are some privateers and smaller teams taking advantage of the opportunity to promoto themselves here.

If you've got info to add, a legit team logo, or anything to help fill in the blanks, hit the contact link at the bottom of the page to send an email to GuyB.
As we've seen, changes happen frequently, just like they will right up until the gate drops on the 2013 season.

Blake Wharton not running the #13 ?

Haven't heard for sure. But given the choice between 13 and a three-digit tribute number, I'm making a guess as to what I think he'd run.

A lot of people like to jump on Genova's case about why doesn't he give a ride to so and so instead of the infamous kamikaze VF... Signing Gavin Faith seems like a great move. The kid has had some great rides on a couple different bikes and teams, with a whole season under one tent he should do some damage. Stoked for 2013!

Pourcel does not have a ride yet for 2013 whereas he can podium in the 450 class, both in SX and MX. I am also sure he is among the only guys that can win 2 or 3 SX. Only RV2, if not injured, is really above the big guns: CR22 and RD5 are close but I do not think JS7 (I may be wrong), TC41 and JB51 have the consistency to win the championship.
I also think Rattray deserves another shot in 250 or 450, he has the speed to podium outdoor, only 2012 was not great for him due to injuries. So these 2, CP and TR, are faster than the 2 hot properties in this list, Hansen, a top 5-8 SX gun who quite surprised everybody at the beginning of the year, as well as Metcalfe, a top 3-8 MX rider who had the same issues as Rattray.

Matt Moss is riding in Australia full time next year on Suzuki. Josh Cachia is taking Moss's US ride now for SX, and perhaps even MX.
