BooKoo Honda rider David Vuillemin is stepping up help to help out his fellow racer James Marshall, who suffered a devastating back injury at the San Diego Supercross early last month.

"I don't know him personally, but he needs our help!" said DV12. "All the profit will go to him and I will be giving money myself, too, at the end of the auction in 10 days!"
