Jeff Ward Racing Kawasaki
Dean Wilson - Confirmed

The team had already re-signed Les Smith for 2013, but sources say that suddenly the team has pulled the plug on operations and will not race next year (they will still pay Smith for his 2013 salary). Stay tuned for more on this story.

Matt Goerke -- We hear Goerke, who rode SX for the BTOSports Team in 2012 before heading to Canada and landing the MX1 title there, will be full time for BTOSports in 2013.
Justin Brayton -- Brayton will be back with the team he rode for in 2010-2011.
Josh Grant -- Not confirmed but rumors suggest Grant and Brayton will be teamed again at JGR. It's 2010 all over again!
Star Valli Yamaha
Jeremy Martin -- Confirmed
Kyle Cunningham -- Confirmed
Notes: When Star and Valli merged last year that left them with a lot of riders. How many will they bring back for 2013? They also have amateur Cooper Webb in the ranks for a debut sometime next year.
Hart and Huntington
Lots of rumors surrounding this team, including a Suzuki tie-up with Ricky Carmichael's involvement. Broc Tickle has been linked to this outfit. We also hear Josh Hansen may be out. Tickle should be on board for indoors and out, the team will have one other 450 rider, possibly for SX only. Ivan Tedesco may stay with the team in that spot.
Remember, this is not a comprehensive list of every rider and team for 2013--but it's what we know to this date.
