Rain, cold weather, and wind turned the Foxborough Supercross into a race of survival of both man and machine, and it was Aaron Plessinger who rose to the occasion, proving untouchable in the mud to take a convincing win in the abbreviated 12-minute plus one lap Main Event.
He was joined on the podium by Cooper Webb in third.
Justin Barcia finished fifth, Chase Sexton sixth, Benny Bloss seventh, Colt Nichols eighth and Dylan Ferrandis tenth; all Alpinestars riders.
