It's true that we just posted the Racer X MX National Preview with this information in it, but it wasn't completely official yet. Well, now it is: Michael Byrne will be joining fellow Aussie Dan Reardon and Kyle Cunningham on Yamaha YZ450Fs for the 2010 Lucas Oil/AMA National Pro Motocross Championship on the Valli Motorsports Yamaha team.
Over the past couple of years while riding for the Rockstar/Makita Suzuki team, Byrne came off of injury for the outdoors to score a handful of podiums both seasons, so he will likely be a threat again this year.
