Daniel Castloo has taken over the wrenching duties on Christophe Pourcel's bike. He spent last Supercross season working for Josh Hansen, and then for Alex Frye during the summer on the Orange Brigade bikes.

Both Zach Osborne and Martin Davalos were aboard 350cc bikes in Las Vegas. For the normally-250-mounted guys, this is an easy change, as the chassis remains the same, and they drop in a 350cc powerplant and ECU, and bam! They're done.
