Racer X has learned that James "Bubba" Stewart and his Kawasaki teammates are now committed to the World Supercross GP races in Canada next month. While official word from Team Kawasaki has not been released, it now seems certain that Stewart and Byrne will join the previously committed Ricky Carmichael, Chad Reed, and Mike LaRocco on the starting gates in Toronto and Vancouver. Also, it appears that BooKoo Honda rider David Vuillemin will miss the Toronto round due to a previous race contract for Geneva, Switzerland, but will compete in Vancouver.

Right now, the only question marks left are Kevin Windham, last year's third-ranked rider, and Team Honda's Ernesto Fonseca.
